What size boiler do I need for my home?

The size of the boiler you need depends on the number of radiators, bedrooms, bathrooms and your property size, as each will require a different amount of hot water.

To determine the exact requirements for your home, it is best to consult with qualified boiler specialists.

Can I install a bigger boiler than needed?

Yes, but an oversized boiler may not be necessary or cost-effective in the long run.

A larger boiler installation can use more energy, so make sure that a bigger size is absolutely necessary before installing one.

What other factors should I consider when choosing a boiler size?

When choosing a boiler size, you should also consider any existing heating system requirements and potential future house extension projects.

Additionally, some boilers come with additional features like timer settings and energy efficiency ratings that may influence your decision.

What happens if my boiler is too small?

If your boiler is too small, it will have to work harder to heat your home and heat hot water. This will cause it to break down more often, and you’ll likely see an increase in your energy bills. You may also notice that your home isn’t as warm as it should be, even when the heating is on.

What boiler is right for your home?

System Boilers

A system boiler is ideal for homes with multiple bathrooms and needs a lot of hot water at the same time. They work by storing hot water in a cylinder, so it’s available when you need it. System boilers are usually more expensive than combi boilers, but they’re also more efficient.

Combi boilers

Combi boilers, also known as combination boilers, provide heat and hot water on demand. They don’t require hot or cold water storage tanks or storage cylinders, so they’re perfect for small homes. However, a small-size combi boiler might need to be more powerful to meet your hot water needs if you have a large family or live in a home with multiple bathrooms.

Regular Boilers

Regular boilers/ conventional boilers are ideal for providing heat and hot water in a large house with multiple bathrooms. They work by storing a hot water tank located in an airing cupboard. This type of boiler requires two tanks – a cold water tank located in the loft and a cylinder for the heated water stored elsewhere in the home. It can also require additional components like a pump and motorised valve.

Electric Boilers

Electric boilers are an alternative to traditional gas or oil-fueled boilers. They’re powered by electricity and are usually considered to be a more eco-friendly option for your home heating system, as they don’t create any emissions and require less maintenance than gas or oil-fired models.

These modern boilers can also be used in tandem with solar panels, providing even greater energy efficiency for your home.
