Choosing the right boiler size is crucial for ensuring energy efficiency and comfort in your home.
The ideal boiler size depends on factors like your home’s size, the number of bathrooms, and your heating requirements.
General Boiler Size Guide
- 1-2 Bedroom Home (1 Bathroom) – 24-27kW Combi Boiler
- 3-4 Bedroom Home (1-2 Bathrooms) – 28-34kW Combi Boiler
- 5+ Bedroom Home (2+ Bathrooms) – 35-42kW Combi Boiler or System Boiler
Factors to Consider
- Hot Water Demand – Homes with multiple bathrooms may need a system boiler instead of a combi.
- Number of Radiators – More radiators require a higher kW rating.
- Water Pressure & Flow Rate – Some boilers work better with strong mains water pressure.
