When getting a new boiler installed in your home it’s a major decision and one that can be confusing with many options available.

To make sure you make the right one it’s important to consider not only the size of your home but your current and future heating needs.

Other factors to consider would be energy efficiency and possible options for renewable energy use. To help you make the right decision, we have put together a quick guide below.

What Boiler Types are Available?

The first step is to understand the different types of boilers that are available, this will help you choose which is right for your home.

Combi Boiler

This is the most popular type of boiler, a combi-boiler works by providing on-demand hot water directly from the mains without needing to be connected to a storage tank.

This means you can shower without the requirement of an additional shower pump.

There’s also no need for a hot water tank which makes them ideal for homes with limited space.


System Boiler

The system boiler works by supplying hot water directly to a storage cylinder and the radiators. All the main components are stored in one unit which does make installation and servicing simpler.

This type of boiler is ideal for homes with multiple bathrooms or if you require more hot water than a combi-boiler can provide.


Conventional Boiler

A conventional boiler has the ability to heat up water and then store it in a hot water tank. It will keep this warm for hours until it is needed.

However, once the stored water runs out, you will need to wait for more to be heated and the tank to refill.

This system works well for larger homes that have multiple homes and lots of radiators. This is also because the tank takes up quite a lot of space and will require an airing cupboard or similar to store it.


What to consider when choosing a boiler

The space you have available

The space you have available in your home will dictate the type of boiler you can have. Houses that have limited storage space will be unable to store a hot water tank and therefore a combi-boiler would be the most obvious choice.

Existing system

Think carefully about whether or not you wish to keep the same system that you currently have. Regarding cost and practicality, keeping the same system does make the most sense, however, there may also be occasions where swapping the system would be the best option.

This will more likely be the case with older homes where there isn’t perhaps the most efficient system in place.

Hot Water Usage

Another factor to consider when choosing your boiler is your hot water usage. If there’s likely to be demand for hot water at multiple outlets, then a boiler with a hot water cylinder will work best. However, you will also need to consider the space you have available for this.


How to choose the right size boiler

Now you should have a good idea which boiler type will work best for your home; the next decision is the size. There’s also this handy calculator you can try.

Demand for hot water

Think carefully about your households demand for hot water, if you have a large family, you will need plenty of hot water each day for washing and appliances.

This will also be the case if you have multiple bathrooms.


Property size

A boiler is not just a source for hot water it will also be the main source of heating for your home. Your choice of boiler needs to be able to provide sufficient heat output for the entire property.

This is something a qualified heating installer will be able to discuss with you.
