Key Points

• Heat pumps are great for a variety of different properties
• Hybrid heating systems allow you to maintain a comfortable home temperature all year round
• Homeowners can see a decrease in energy bills
• There is no need to install a new hot water cylinder or make alterations to your home

What are heat pumps?

Heat pumps are a type of a heating and cooling system that uses environmentally conscious energy to generate heating and hot water to your home. They work by extracting thermal energy from the ground, air or a local water supply. The heat pump then converts this thermal energy into heating and hot water. 

Heat pumps operate by collecting heat through an external collection system, which are pipes containing liquid filled with antifreeze to transfer the heat from ambient temperature. 

Can you have a heat pump and a combi boiler?

Yes, you can have a heat pump and a combi boiler, using what is known as a hybrid heat pump. The boiler is used to ‘top-up’ a low temperature heat pump in order to meet the demands of a property in which a heat pump cannot do it alone. It also continues to provide hot water.

Heat pumps usually work at lower temperatures than boilers. Without the correct insulation in our homes, or upsizing radiators, low temperature heat pumps aren’t suitable for existing properties. If the heat pumps are fitted incorrectly, there are risks that homes may fail to heat or there may be a huge increase in electricity bills. 

Hybrid heat pumps let the heat pump run at an efficient temperature of around 40C, which will provide sufficient heat for a large part of the year. As the outside temperatures drop, and when the hot water is used, the boiler can step in.

In some cases, you may need to upgrade your radiators to a larger size to ensure they have enough surface area to emit enough heat in order to comfortably warm the room. 

However, in recent years it has become common practice for heating installers to install ‘oversized’ radiators. This is to ensure that the radiators are actually capable of heating a much larger space and would therefore be suitable for heating a room even if they operated at a lower flow temperature. 

If your radiators are ‘oversized’, then it is very likely you won’t need to change them when you get a heat pump. The best way to find out is to speak to our professional heating system installers at Lacey Plumbing & Heating to get a definitive answer.

Can you install a heat pump onto a system which already has a combi boiler?

Yes, you can add a heat pump to a combi boiler system, but there are a few things you should consider before doing so. 

Determine your current boilers setup 

You’ll first need to determine the existing setup of your boiler before you buy a heat pump. This will help you establish the heat pumps size, type and location. 

Consider your homes heating needs 

When you’re replacing your heat source with a heat pump or adding in a heat pump, consider the current heating needs of your home. It is better to have a full professional survey before you can consider installing a heat pump. 

Calculate the costs of the heat pump 

To calculate how much a heat pump will cost, you should first determine how much your current boiler costs to run. You can do this by asking your energy provider. The next step is to consider the energy savings you could benefit from with a heat pump instead of a traditional boiler. 

Once you’ve established what the difference is between the two, you can then proceed with either sticking with your current heating system or upgrading to a heat pump. 

Are there benefits to keeping your combi boiler and having a heat pump?

There are a number of benefits of having a hybrid heating system, including:

• Less need for alterations to your home – With a hybrid system you will still use your combi boiler for hot water, and it will kick in to top up your heating when needed. If you were to replace your combi boiler for a heat pump, you would need to install a cylinder for hot water which needs a space to be installed, and other changes to radiators and pipework may be needed.

• Reduced carbon emissions – Heat pumps have smaller running costs than boilers, producing 3 times as much energy as they use. However, in colder temperatures, your heat pump will have to work harder to keep your house warm.
  
  This is where your boiler will come in. Thankfully, since you won’t need to rely on your boiler as much throughout the year, it can help to reduce your carbon footprint.
  

Reliability all year round – A hybrid heating system is smart enough that you will have the best heating system all year round, no matter the weather. This means when temperatures drop and your heat pump will have to work harder, the boiler will kick in to sort it out without you having to lift a finger.

What is a condensate pipe?

A condensate pipe is an additional pipe that is fitted to carry away waste water from a condensing boiler. It is normally a piece of plastic and it runs from the boiler to a household drainage pipe or soakaway outside. 

Evidence of condensed water running through the pipe is an indication that your boiler is working as it should be. Long periods of cold weather can cause the pipe to freeze, affecting the operation of the boiler.

Where is the boiler condensate pipe?

The condensate pipe runs from the boiler to an appropriate existing waste pipe  or external pipe. You will be able to see the condensate pipe underneath your boiler, and it should be the only plastic pipe visible. 

If your condensate pipe is connected to an external drain pipe, it will be found outside your property leading from your boiler. 

How to tell if condensate pipe is frozen

If your condensate pipe is frozen, you may hear gurgling noises coming from your heating system, and the boiler may shut down.

This is a failsafe mechanism to protect the boiler from water going back up the pipe and inside the boiler, which could cause damage to the electrics.

How to thaw a frozen boiler condensate pipe

If your condensate pipe has frozen, you shouldn’t worry. It can be sorted in a few steps likely without having to contact a heating engineer. 

Before you start, you should first find the blocked part of the pipe. This way, you can be sure you’re thawing out the right part of the pipe. Most blockages occur if there’s a bend or dip in the pipe. 

You can unfreeze the pipe in one of two ways:

• You can hold a hot water bottle, heating pack or warm cloth around the frozen part of the pipe, or; 
• You can pour hot water over the frozen area. Make sure you don’t use boiling water as this can cause the plastic pipe to melt.

After you’ve unfroze the pipe, you might need to reset your boiler. Some boilers may do this automatically, so it’s a good idea to check your boilers manual for the next steps. If you don’t feel comfortable unfreezing the condensate pipe yourself, you should always get in touch with a qualified heating engineer for expert help.

If you are really struggling to defrost the pipe a heating engineer can attend and cut the pipe as a temporary measure. It would then need to be reconnected when the temperatures increase.

How to prevent a boiler condensate pipe from freezing again

There are a few ways you can prevent your condensate pipe from freezing again. Firstly, you should take the following steps into account as the colder months approach:

• Use foam pipe insulation to cover the condensate pipe.
• Consider having your condense pipe upgraded to a larger bore pipe, If you have an older installation it will be a smaller diameter. 

If you have a Worcester Bosch boiler, they have a CondenseSure device which can be fitted to prevent boilers from freezing in temperatures as low as -15°C.  

Unfortunately, sometimes, when the temperatures are extremely low for prolonged periods there’s not much that can be done to completely prevent a pipe freezing, but at least you can be aware of what it is and how to deal with it.

Low shower water pressure is a problem for many homeowners who have a combi boiler and it can be extremely frustrating. 

If you have a combi boiler, your options in increasing your water pressure are limited. Despite this, there are a few steps you can take to improve your boiler flow rate. 

Is shower pressure better with a combi boiler?

You may expect a combi boiler to provide better shower pressure since it gets the water from the mains, but this generally depends on how strong the water pressure is from the mains itself.

Homes with strong water pressure from the mains will benefit from a strong flow of water from taps and showers. However, for those with low water pressure, you may struggle to get a good flow of water pressure to your shower, even if you do have a combi boiler. 

A combi boiler in a home with low water pressure may also struggle to send enough hot water when multiple taps are open, such as a shower and a downstairs sink. 

How do I increase water pressure in my shower with a combi boiler?

Since combi boilers are mains fed, you are limited in options when it comes to increasing water pressure. Unfortunately, you can’t use a pump directly from the mains to provide an extra boost, but there are a few steps you can take to ensure you get the water pressure you want. 

When you’re choosing a boiler, it’s always important to check it is powerful enough to supply a strong, consistent flow of water. You should be looking for an appropriate flow rate, which is simply how much water can pass through the appliance to feed showers and taps once the boiler is working. An ideal flow rate for a combi boiler is at least 12-15 litres of water per minute. 

Choosing a combi boiler with a good flow rate will help you to optimise hot water pressure throughout your home. However, it is important to remember that you are restricted in terms of flow rate by the mains pressure delivered to your property. 

This means that if you get a combi boiler with a maximum water supply that exceeds your mains water supply, you could be wasting your money as your boiler won’t be reaching its full potential. 

It may also be worth checking for blockages and leaks, as well as checking the mains water supply to see if there are any other issues affecting the water pressure

Are there other ways to increase shower water pressure with a combi boiler?

One alternative to increase water pressure with a combi boiler is by having an electric shower. 

Electric showers are a great option as they take cold water directly from the mains, bypassing the need to take water from the boiler. Instead, a heating element in the shower unit itself heats the water to the desired temperature. 

As they don’t take water from the boiler, electric showers provide a consistent and reliable flow rate even when multiple taps are open and being used at the same time. 

The stronger the kilowatt rating of the electric shower, the stronger the flow. However, this is only to a certain extent as the water still comes from the mains. 

If you are struggling with the water pressure coming from your combi boiler, or you’re interested in having an electric shower fitted, feel free to contact our team today.

Why should you drain your combi boiler?

Generally speaking, the main reason why you should drain your combi boiler is to eliminate any build up of sludge and limescale from your radiators and pipework. 

You may also choose to drain your combi boiler to avoid coming home to frozen pipes if you are going to be away from home during the winter months.

We highly recommend leaving the job of draining your combi boiler to a professional team. Attempting it yourself could result in damage to your heating system and may void your warranty. 

When should I drain my combi boiler?

There are a few occasions in which you may want to drain your combi boiler:

• You are going to replace the radiators or pipes
• To clear any blockages from the heating system
• To avoid coming home to frozen pipes in the winter if you plan on going away for a while

Do I need to drain my combi boiler to change a radiator?

Yes, before you fit any new radiators or pipes, make sure you turn off the water and drain the system. 

This will help to remove any debris within your heating system, making it ready for your new radiators.

How to refill a combi boiler

Once you’ve drained your combi boiler, you will need to refill the system. To do this, you will need a filling loop. 

The filling loop connects the mains water pipe with the central heating pipe. It is normally found under the boiler and looks like a flexible silver hose connecting two pipes. 

There will be a valve at each end which will both need to be turned to open to allow the water to flow into the heating system.

When the valves are open, you should be keeping an eye on your boiler’s pressure gauge. It should sit somewhere between 1.5 and 2, but you should always check the manufacturer’s instructions. 

Once the pressure gauge is correct, you can close both of the valves. Your combi boiler will now be refilled. 

Please note that different boilers have different types of filling valves. You need to check the manufacturer’s instructions for your particular boiler.

How often does a combi boiler need topping up?

The pressure in your combi boiler will usually need to be topped up once or twice a year. 

The benefits of combi boiler draining

The advantages of draining your combi boiler include:

• Removal of sludge and sediment build-up
• Improve the efficiency and functionality of your boiler
• Prolong its lifespan
• Prevent other issues from arising
• Keep you clear of unnecessary or preventable repair bills

What is a heat pump?

A heat pump takes energy from outside and moves it into your home through the use of electricity. However, the quantity of heat delivered into your home is much greater than the quantity of electricity used to power the heat pump itself. 

Since the heat pump captures heat that is already present in the environment, the system itself does not burn any fuel, and so will not emit any carbon dioxide. 

Can a heat pump heat a whole house?

Yes, a heat pump can heat and cool a whole house. Depending on the type of heat pump you have installed, you can even accomplish precise temperature control throughout different rooms of the house. 

The main differences between heat pumps and boilers

If you’re only just hearing about heat pumps, don’t worry, you’re not the only one. However, they have become increasingly popular over the past few years, with many swapping out their boilers for new heat pumps.

There is a main fundamental difference between heat pumps and boilers, being that:

• Heat pumps operate by extracting heat from outside air and transferring it to inside your home.

• Traditional boilers, on the other hand, work by using natural gases, propane or heating oil to create heat which is then circulated through your home’s pipes. 

How do you know if your home is suitable for a heat pump?

Before you consider a heat pump, you should take some steps to get the best results. This is because the more efficient your home is, the more economical a heat pump will be. 

First, you should find out how well insulated your home is. This is because the correct insulation helps to retain heat and stop energy from escaping. A well insulated home will increase the efficiency of your heat pump, reduce its running costs and therefore, save you money. 

Some methods you can use to get your home ready for heat pumps include:

• Checking if you need loft and cavity wall insulation
• Draught-proofing windows and doors to stop heat from escaping 
• Sealing any gaps or cracks around windows, doors and sockets 
• Installing double glazing if you don’t already have it

Heat pumps vs boilers: Installation costs

The costs to install a heat pump is significantly higher than for a boiler installation. This is because boilers can be installed almost anywhere, whereas a heat pump will need to be installed on one of the outside walls of your home or be placed on the ground next to it.

The installation for heat pumps is also much more complex, which is another reason why it is more expensive than boiler installation. 

On average, installing a boiler can cost anywhere from £1,000 to £4,000, whereas installing a heat pump can cost from £7,000 to £49,000. 

Heat pumps vs boilers: Space needed

Traditional boilers don’t take up too much space; especially the likes of combi boilers which don’t require a hot water cylinder. This makes boilers more suited to smaller properties where space might be limited. 

Heat pumps however, require a large amount of space. This is because they require both outdoor and indoor space for the actual unit itself and a hot water cylinder. If you are considering installing a heat pump in your property, then you’ll need to ensure you have enough room available. 

Heat pumps vs boilers: Running costs

Heat pumps are usually cheaper to run than boilers because they are powered with electricity rather than gas. 

You can further reduce the running costs of heat pumps by installing solar panels on your property. This is because your heat pumps will largely be powered by solar energy throughout the day, helping to keep your running costs to a minimum.

Heat pumps vs boilers: Efficiency

When it comes to efficiency, modern boilers can boast an impressive efficiency rating of 99-100%. 

However, this is no match to the efficiency of heat pumps at 300-400%. While you won’t waste energy using an electric boiler, you will get 3 to 4 times the heat for every kW with a heat pump. 

Heat pumps vs boilers: Heat output

Generally speaking, heat pumps do generate a lower level of home heating compared to boilers. Heat pumps often provide an output of around 55°C, which is comparably low compared to modern combi boilers which are usually in the range of 70-85°C. 

These lower heat output may not be something families are looking for; however, you should remember that the heat output also needs to be weighed up against the overall running costs. 

Heat pumps vs boilers: Carbon footprint

When it comes to the environmental impact, heat pumps are the clear winners. Heat pumps run on electricity, which release fewer emissions than gas and could help you reduce your annual footprint by almost 45%. Heat pumps are around three times more energy efficient than gas boilers, meaning they use less energy while they operate. 

Boilers, on the other hand, are powered by fossil fuels, which are responsible for around 75% of the world’s global emissions. 

Heat pumps vs boilers: Maintenance and futureproofing

Heat pumps generally have less moving parts than a boiler, meaning they are safer and generally rely on less maintenance. However, it is worth noting that heat pumps will still require different maintenance checks. 

Air source heat pumps need to be serviced by a heat pump engineer every two to three years. As for day to day maintenance, you should regularly check for any debris in the outside unit to make sure everything is running smoothly. 

Ground source heat pumps also require little maintenance since most of their infrastructure is underground, making it less susceptible to weathering. 

Boilers, on the other hand, need to be serviced every year, which will cost between £50 and £100. On a day to day basis, you should ensure that your boiler is well ventilated, and you should also keep an eye out for any leaks or pressure issues.

Pros and cons of heat pumps vs boilers

There are a variety of different pros and cons to both boilers and heat pumps that you should be aware of before you make a decision on what’s right for you. 

Should I switch from a boiler to a heat pump?

Switching from a boiler to a heat pump could save you a significant amount of money on your energy bills thanks to the increased efficiency and lower running costs. They are also durable, require less maintenance and will help to reduce your carbon footprint. 

However, they are an expensive investment, which is why it is always important to seriously consider your decision before you dive into buying a heat pump. 

If you’re thinking about getting a heat pump installed in your home, contact our team at Lacey Plumbing & Heating to find out how we can help you. We will take the time to consider what sort of heating system is best for you and your home, and provide advice on how you can reduce your costs and improve efficiency.

Ideal boilers have been trusted across the country for years now. However, there may be times when your Ideal boiler isn’t performing the way it should. 

In this guide, we’ll discuss common Ideal boiler issues, how to fix them and some common error codes you may experience. 

Common Ideal boiler problems

There are a few common Ideal boiler problems that you may experience, including the following listed below:

• Boiler failing to ignite (L2) –  When an Ideal boiler fails to ignite more than 3 times, it will lock out. This essentially means that your boiler has shut down. If you’re unsure if your boiler has locked out, an orange light will display on the boiler.

• Blank display – If nothing is appearing on the boiler, it suggests there is no power. This likely means a component within the boiler has failed, which will likely require the help of an engineer.

• Loud noise when igniting (L2) – Loud noises when igniting can be a sign that too much gas was in the ignition prior to lighting.

• Gurgling noises (L2) – If you hear gurgling noises from your Ideal boiler, it is likely caused by blocked waterways from the boiler to the condensate.

• No hot water (F1, F2, L2) – Check your Ideal combi boiler is turned up on the front, then check that the isolation valve underneath the boiler on the cold mains pipe is open. If neither of these seem to be the cause of the issue, then it is likely a problem with the appliance.

• Low water pressure (F1) – Your water pressure should be sitting around the 1.5 pressure bar mark.

• Flame loss (F2, L2, FN or LN) – There are many causes behind a flame loss, including a faulty fan, insufficient gas supply, issues with electrical components and low gas pressure. 

Ideal boiler warranty

Ideal boiler warranties can vary between 2 to 12 years, but this may be limited to 12 months if you don’t register your boiler within 30 days of installation. 

Ideal heating warranties offer customers full parts and labour repair services, or boiler replacement free of charge if the boiler has any mechanical or electrical breakdowns due to fault with materials or installation.

How do I reset an Ideal boiler?

The reset procedure on your Ideal boiler will vary depending on the exact model of your Ideal boiler. However, most modern models will have a dedicated reset button. 

You can use the following steps to reset your Ideal boiler:

• Esprit Eco 2 – Simultaneously press down the select and arrow up button together for a few seconds.

• Logic – Turn the control knob to the reset position, and then immediately turn back to the setting of your choice.

• Logic+ and Vogue Max – Press the dedicated reset button underneath the digital display.

Why is my Ideal boiler firing but there is no hot water?

There are a few common reasons why your Ideal boiler is firing but there is no hot water. In this situation, the best thing you can do is act quickly, and get in touch with our heating specialists at Lacey Plumbing & Heating. Being without hot water at home can cause real issues, so it’s best to call us as soon as possible. 

Some of the common reasons why your Ideal boiler is not producing hot water include:

• Thermostat issues
• Incorrect radiator settings
• Faulty diverter valves
• Faulty boiler settings
• Broken internal components 

How do I fix the pressure on my Ideal boiler?

If your Ideal boiler is experiencing low water pressure (F1), don’t panic, this is something you can easily fix yourself using the following steps:

1. Turn off your boiler

2. Locate your boiler’s permanent filling loop. This will be beneath the boiler.

3. Open the valve on the filling loop until the pressure gauge shows 1 to 1.5 bars of pressure, and then close the valve. Do not increase the pressure to above 1.5 bars as this can damage the boiler itself and the system.

4. Use a cloth to catch any drops of water from the air break on the filling link. Don’t worry, a small amount of water appearing is normal.

5. Finally, check your central heating system and your radiators for any signs of water leaks.

If this doesn’t work, you can head over to our full guide on boiler pressure for other useful tips on how to repressurise your boiler.

How do I find the error codes on my Ideal boiler?

If your Ideal boiler develops a problem, an error code will show on the display screen to help you identify the issue. 

Each boiler has its own code, so make sure you check the guide that came with the boiler. 

Ideal Logic Max and Logic Plus boiler error codes

Common Ideal boiler error codes

With energy bills still on the rise, many homeowners are looking for ways they can save money on their heating bills. One way you can save money is by replacing your old boiler with a new, energy efficient combi boiler. Keep reading this guide to find out how a new combi boiler could help save you money. 

Is it worth investing in a new boiler?

If you’ve had your old combi boiler for more than 10-15 years, then it is definitely worth investing in a new boiler. Not only will a new boiler be much more efficient, it will also prevent you from paying out on expensive boiler repairs thanks to the improved reliability.

As your boiler begins to age, it loses its efficiency, as you can see in the list below:

• 0-10 years = 90%+
• 10 years = 85%-80%
• 15 years = 80%
• 20 years = 75%
• 25 years or more = 70%-60%

Will a combi boiler reduce my bills?

Yes, it is most likely that upgrading to a new combi boiler will help to reduce your heating bills. This is because new combi boilers are much more efficient, with nearly all condensing combi boilers having an ErP rating of A or above.

To determine if a combi boiler will reduce your bills, you should:

• Compare the boiler model ratings. The higher the rating, the more efficient it is. 
• Take into consideration things such as energy price caps, energy prices and your typical energy bills

Don’t worry if you don’t know where to start with this; our team at Lacey Plumbing & Heating will help you to calculate your potential savings. 

Will I save money switching to a combi boiler?

Again, this will depend on your unique circumstances. However, if you currently have an old boiler that is around 15 years old, for example, it will likely be running on an energy efficiency rating of less than 70%. 

Having a new combi boiler will help lead to significant energy saving costs since the running costs will be much less, which in turn will reduce your annual spendings.

When should a boiler be replaced to be most cost effective?

In terms of when you should replace your boiler, you should ideally look to replace it every 15 or so years. This will help to ensure that the efficiency isn’t dropping below 70% and ensure it still remains reliable and safe. 

The time of year you replace your boiler can actually also affect how much money you can save. It’s a good idea to replace your boiler in the summer rather than winter, since there are lower demands for boiler repairs and replacements. Replacing your boiler in summer means you can be prepared for the winter with an energy efficient boiler that you know you can rely on.

How to calculate potential savings from a new combi boiler

To calculate your potential energy savings from installing a new combi boiler, follow the steps below:

1. Take your annual heating bill from last year
2. Estimate the efficiency of your current boiler (you can use our guide above)
3. Estimate the efficiency of your new combi boiler 
4. Deduct the existing boiler efficiency from the new boiler efficiency to calculate the efficiency improvement. For example, 85%-75%=10%
5. Multiply your annual fuel bill by the efficiency improvement to get your savings figure. For example, if your annual bills are £800, 800×0.10=£80 savings per year. 

If you’re interested in upgrading your old boiler to a new combi boiler, contact our team today to discuss your heating needs.

What is the lifespan of a combi boiler?

A combi boiler will usually have a lifespan of between 10 to 15 years, however,  this can vary depending on the specific make and model you have. 

The lifespan can also be affected by how often you use it and whether it has been serviced regularly. 

How often should you replace a combi boiler?

Although boiler technology is always evolving, the best way to ensure you have the most efficient and reliable boiler is by upgrading your heating system every 15 years or so.

This doesn’t mean your boiler will suddenly stop working after 15 years. Instead, it is simply a general guideline, suggesting that after this period of time, it’s likely your boiler will begin to become more inefficient and so it would be more cost effective to upgrade to a new one. 

How long do Worcester Bosch combi boilers last?

Whilst Worcester Bosch themselves state there is no exact time frame for how long their boilers will last, they stick by the 10 to 15 year rule. Again, this will depend on a number of different factors, such as maintenance and the type of boiler. 

How long do Baxi combi boilers last?

Like Worcester Bosch, Baxi suggests your boiler should last from 10 to 15 years as long as it is serviced annually and well maintained. 

How long do Ideal combi boilers last?

Again, like the others, Ideal suggests that their boilers will last from 10 to 15 years provided that they are correctly serviced and maintained.

How do you know if your combi boiler needs replacing?

Buying a combi boiler can be an expensive decision, so it’s important to be aware of the signs that your combi boiler needs to be replaced. Listed below are the key signs to look out for. 

It’s over 15 years old 

Time is a great sign of when you need to replace your combi boiler. After 10 to 15 years, you may start noticing that things are going wrong with your boiler and losing efficiency. 

Your energy bills are increasing 

Old boilers tend to be much more inefficient than newer boilers, and therefore cost more to run. If you notice your heating bills are rising significantly, this may be time to invest in a new combi boiler. This will save you money, as well as help you to have less of an environmental impact. 

Common boiler problems are arising 

There are a number of reasons why your boiler may not be working. However, if you are noticing common problems such as gurgling, banging and leaking more often than usual, this could be a sign that your boiler needs to be replaced. 

Your boiler flame is yellow or orange 

If your boiler flame has changed from blue to yellow or orange, this is a sign of complete combustion which can increase the risk of carbon monoxide leaks. While fixing the issue should be straightforward for a heating engineer, if the issue persists,  it’s time to change your boiler. 

You can smell gas 

This one is obvious, but as soon as you smell gas, you should turn your boiler off and contact our emergency engineers immediately. A gas leak can be extremely dangerous, and if your boiler leaks gas, it is often a sign that it needs to be replaced.

Should you replace an old combi boiler if it works?

If your combi boiler is less than 8 years old, then repairing any issues it may have would be a more sensible option. 

However, if your boiler is more than 10 years old, then repairing any potential problems may not be the best option since chances are you will face more repairs in the future, which can become incredibly costly. Instead of paying for multiple repairs, it would be a much more cost effective option to replace your old boiler with a new, A-rated combi boiler. 

If you are interested in upgrading your old combi boiler to a brand new one, contact our expert boiler specialists for more information on our boiler installations. We will take the time to review your current combi boiler and ensure your new one works exactly how you need it to.
