If your boiler is giving you a hard time and you find out that its repair cost is quite pricey, then it’s better to consider getting a boiler replacement. After all, a new boiler is more efficient and can save you some money on your heating bills.  

However, before rushing and buying the first boiler you see online, there are things you should know beforehand.  

Should I worry about the gas boiler ban? 

You might be thinking if it’s worth buying a gas boiler with the upcoming gas boiler ban. Well, to put your mind at ease, the ban which is taking place in 2025 is only meant for new build homes. It does not apply to other homes. So you can replace your boiler with a gas boiler and not worry about that.  

If you can afford another alternative to gas boilers such as heat pumps, then go for it. However, for the time being, gas boilers are an affordable way to heat your home and provide you with hot water.  

What brand to choose?  

To begin with, you would want to start the process by choosing a boiler brand that is trustworthy. In order to identify a good boiler brand, you can just check how many awards they have won. Worcester Bosch, for the last ten years, have won the which? Best Buy award. This shows that they have been in business for a long time and that they are quite reliable.  

You would want a company that lasts long in order to guarantee that they will be there in the long run to honour your boiler warranty. When you are offered a long warranty, say for ten years, then it means that the company has trust in its product and knows that it can last that long without breaking down, given that it is serviced regularly.  

It is advisable to choose a boiler that will not easily break down in the foreseeable future. You might initially pay more but you will save on the repair cost in the long run.  

What is the right kW output for my home? 

KW output simply means the boiler’s power to supply a home with hot water and heat. kW output is relative to size. The bigger your home is, the more kW output is needed to supply your home with hot water or heat. 

Here at Let’s Heat we can help you determine the right kW output your home requires. This is simply done by calculating the number of rooms and showers your home has.  

Another thing to keep in mind is whether you are planning to extend your home in the foreseeable future. If that is the case, then you might want to get a boiler with a bigger kW output.  

You can get in touch with us to know more about kW output and what boiler size your home requires.  

Is it worth buying a new boiler? 

New boilers are far more energy-efficient than older ones, so replacing your boiler with a newer model can help you save money on your heating bills. It can also help you reduce the carbon emissions of your home. 

What is the average life of a boiler? 

If you have recently bought a new boiler or maybe you are considering when it’s time to get a replacement, you will most likely be wondering how long a boiler can last. For an average household, boilers will last up to 10-15 years. Though it’s important to understand this timespan is conditional to different factors.  

What questions should I ask when getting a new boiler? 

You can start by asking about the warranty with the new boiler and whether there are any guarantees on the entire installation e.g. pipework and other plumbing that might be necessary. You should also try to find out whether any warranties include parts and labour.  

What are some of the essential qualities of a good boiler? 

 A good boiler should have a high rate of heat transfer and better combustion efficiency. Its initial cost, running and maintenance cost should also be low. The boiler should have safety apparatus and reliable controls. And finally, the mud and other deposits should not collect on the heating plates. 

Do boilers become less efficient with age? 

Without a doubt, boilers can become more inefficient the older they get, especially if they aren’t well maintained or serviced regularly on an annual basis. Older boilers, because of their inefficiency, will result in higher home heating bills compared to a newer boiler replacement. 

What is meant by a Condensing Boiler? 

The terms condensing and non-condensing can be confusing to people shopping for a new boiler. Condensing is not a type of boiler, but rather a technical feature. In a Condensing boiler you get a much bigger heat exchanger. They also produce additional heat from the fuel. The same fuel that would have been wasted in a non- Condensing boiler. As a result, they are more efficient. 

non-condensing boilers are less efficient by 50% since a lot of heat was lost in the combustion exhaust gases. On the other hand, new boilers would capture this heat and use it to heat water. 

condensing boilers are energy efficient by 90%. They use excess energy to heat your property. Not to mention, they are environmentally friendly and reduce your heating bill. 

What kind of boiler you currently have :

There are four types of boilers. Knowing what type you have makes it easier for you to make the right choice. Here are the four main types of boilers: 

Combi boilers 

Combi boilers are the most common boiler type installed across the UK. They are cheap and easy to fit. What is more, they do not require an additional water storage tank placed in the airing cupboard or loft. Combi boilers are extremely efficient because they heat water from the mains on demand.  

Heat-only boilers 

Known also as regular, traditional, conventional or vent boilers. They are quite difficult to replace because they have both a hot and a cold water storage tank. They are usually replaced by combi boilers by most people. That way, you will have more space in your home.  

System boilers 

System boilers are ideal for homes with a high demand for hot water. Because they have a separate hot water storage tank, they can provide hot water to multiple bathrooms at the same time. Their only drawback is that they use a storage tank.  

Back boiler 

Back boilers can last as long as 25 years. However, they are very inefficient and can cost you a lot on your heating bills. They are located behind gas fires. Removing a back boiler is quite a difficult job and can take as long as 2 days. Replacing this type of boiler will save you money on heating bills.  

How can a new boiler save me money? 

We have mentioned before that a new boiler is sure to be more efficient and as a result can save you some money on your heating bills. However, there are some other ways to save money with a new boiler. 

Smart thermostats 

A smart thermostat is to be connected to your boiler. This can allow you to control the temperature of your home by simply using a smartphone.  

A smart thermostat has the ability to learn about your habits and heat your rooms accordingly and when they are occupied. It will learn not to heat a room that is not often occupied at a certain time.  

Thermostatic radiator valves 

Thermostatic radiator valves are similar to smart thermostat in the fact that they offer more control over your heating. A traditional radiator valve has two settings; it’s either on or off. But a thermostatic radiator valve can allow you to change the temperature dial for each radiator.  

You can control the different rooms in your home according to their temperature. You can turn down the heat for a room that is often hot or turn up the heat in a room that is often cold.  

This process will lessen the demand on your boiler. This can allow your boiler’s lifespan to increase.
