What Size Boiler Do I Need?

If you are considering buying a new boiler for your property, you are probably wondering what size boiler to buy. Most combi boilers come in several sizes, enabling you to choose the right one for your home. Clearly a smaller boiler will be ideal for a small property, whereas a large house will need a much bigger one.

Why does the size of boiler matter?

If you size the new boiler properly, you will be able to enjoy a much more efficient boiler. This means it will cost less to run, which is good news for you in the long run as it will have a significant effect on your energy bills.

How do you work out what size boiler you need?

A good rule of thumb is to go by the number of radiators the boiler will be responsible for heating. For example a small property with fewer than ten radiators should find the smallest size boiler is adequate. Conversely if your home is much bigger and has perhaps twenty radiators, you would probably need the largest size of boiler. Boilers are measured in kw (kilowatts).

Consider the number of occupants as well

Of course if you live in the property on your own you will demand less of your new boiler than if you had a family with three young children. If you live on your own you may run a shower or do the washing up, but you will be unlikely to do both at the same time. However a family may well place more demands on the boiler in this way, and so a larger boiler would probably attain better results.

How can you be sure you choose the right boiler?

Consider the boiler you will be saying goodbye to. Were you happy with the service it gave or did it struggle to meet the demands of the household? This can be a good way to gauge which boiler to get now.

You can also get advice and quotations from experts in the industry who are qualified to install new boilers. Always look into companies you trust and get more than one quotation. See what they recommend and use your own knowledge from the information above to help you arrive at the best decision for your home. As you can see, the size of boiler matters a lot, so make sure you get the right one.
