Boiler size is one of the most important boiler considerations. A boiler that is too large for your home can end up costing your household more money in heating bills. However, a boiler that is too small may not be able to heat your home. Here at Paul Robinson Heating and Plumbing Services, we are experts in boilers and heating. Consequently, we have produced this guide to help you choose the right size boiler.
Size of the household
Generally, the larger the household, the larger the boiler required. A family of 4 will clearly require more hot water than a person living alone. As a result, a boiler with a larger power output would be necessary to meet the larger demands.
The property size
In addition, the size of the actual property also has an impact. This is because larger properties tend to have more bathrooms and more radiators that will require hot water from the boiler. As a result, a smaller home will need a boiler with a smaller power output.
The level of insulation
A property with loft insulation, double glazing and good cavity wall insulation will stay warmer for longer. Consequently, less heat will be required by the central heating system to maintain an ambient temperature. As a result, homes with good insulation may be able to downsize their boiler.
Boiler sizes:
Combination boilers are available in 3 sizes. These are:
- 24-27kw- The smallest size is suitable for flats and small homes. It will easily service less than 10 radiators and one bathroom.
- 28-34kw- The medium size boiler is suitable for 3-4 bedroom homes. It will service two bathrooms and up to 15 radiators with ease.
- 35-42kw- The largest size boiler is suitable for large properties and hotels. It will service multiple bathrooms and more than 20 radiators.
