When Do I Need to Replace My Boiler?

If you use a boiler to provide hot water and heating for your home, it is likely to make up a significant proportion of your home’s energy bills. An inefficient boiler is one which doesn’t convert the majority of fuel into energy. It is therefore expensive to run and doesn’t produce as much energy as it should. In effect, you are spending more to get less, and if this is the case in your home, it could be time to replace your boiler. On the other hand, it is worth remembering that boiler replacement costs can be high. On average you can expect to spend somewhere in the region of £2,000 on a new boiler. You need to make sure that amount you spend on will be offset by lower energy bills. So how do you know if your boiler is inefficient, and if it really is time to get it replaced?

New vs old boilers

Condensing boilers came into widespread use in the 1990s. They are much efficient than the old style boilers because they are able to re-use some of the energy they produce, which means they need less fuel to generate the same amount of energy. The Energy Savings Trust estimates that you can save about £300 per year on average by replacing an old style boiler with a new one.

So efficient are condensing boilers that they have replaced the old style completely, and all new boilers now use condensing technology. Beyond that, however, there are different types of boiler and the one you choose could also help you to save money, depending on what you need to use it for, and how large your home is.

Types of boilers

The two main types are heat-only and combination boilers. A heat-only boiler is the most efficient kind for heating up water, and it provides hot water for radiators and a hot water cylinder. If you have a large property with a lot of people, it is a good idea to have this type of boiler, but remember, you will need space for the cylinder as well as the boiler itself.

A combi, or combination, boiler does not require a separate hot water cylinder as it heats water only as and when it is needed. This type of boiler is more suitable for small homes with fewer people, as you will only be able to draw hot water from one tap at a time.

If you think you might need a new boiler, think carefully about central heating costs in your home, as well as the type of boiler which is suitable for your needs. If the savings you can make on your energy bills justify the cost of buying and installing a new boiler, it could be time for you to get an online boiler quote so you can find the best possible deal for you.
