How to Determine the Right Boiler Size for Your Home 
When you’re replacing the boiler in your home, you need to make sure it is the right size. Getting a boiler that is too small can cause it to overwork trying to heat your home and provide an adequate supply of hot water. This in turn can drive up your energy costs. Here are some tips for buying the right size of boiler for your home.
Boiler Sizes
When purchasing a boiler, you will need to decide how many kilowatts you need. Combi boiler sizes include the following ranges:
- 24 to 27 kW – A boiler of this size will be best for a small home or flat with one to two bedrooms, one bathroom, and up to 10 radiators.
- 28 to 34 kW – This size of boiler could suit a house or flat with three to four bedrooms, one to two bathrooms, and up to 15 radiators.
- 35 to 42 kW – A boiler this size would be suitable for a large home with four or more bedrooms, two plus bathrooms, and up to 20 radiators would need this size boiler.

Water Source
If your home has more than two bathrooms, you should consider buying a conventional boiler, as combi boilers are not recommended for houses of that size or larger. Combi boilers are fed water from the mains, while conventional or systems boilers from large cylinders.
If you need a new boiler because yours has died or because you want something more energy efficient, consider the size of your house to calculate the right size.
