Should you get a regular, system or a combi boiler?
A system or regular boiler will most likely be the best boiler for a large house with 5 bedrooms and 2 or more bathrooms. However, choosing between a combi, system, or regular boiler will depend on your home’s characteristics, such as its layout, hot water requirements, and available space.
- Regular boilers suit homes with traditional heating systems and multiple bathrooms.
- Combi boilers are better for smaller new-build apartments with lower hot water demands.
- System boilers are ideal for homes with high hot water needs but limited space, as they integrate many components into the boiler itself.
To better understand the best boiler size for a 5 bed house, we've compiled the table below, specifying which boiler type would be ideal for each household size.
| Household size | Boiler type |
|---|---|
| 1 to 2 bedrooms (1 bathroom) | Combi boiler |
| 1 to 2 bedrooms (2 bathrooms) | Combi boiler |
| 2 to 3 bedrooms (1 bathroom) | Combi boiler |
| 2 to 3 bedrooms (2 bathrooms) | Combi boiler |
| 2 to 3 bedrooms (+3 bathrooms) | Regular/System boiler |
| 4 to 5 bedrooms (1 bathroom) | Combi boiler |
| 4 to 5 bedrooms (2 bathrooms) | Regular/System boiler |
| 4 to 5 bedrooms (+3 bathrooms) | Regular/System boiler |

Furthermore, you should only consider a regular boiler if you already have one installed. These complex heating systems require additional water feed tanks in the loft and extra plumbing work, increasing your boiler installation costs.
A system boiler is a modern version of the regular boiler, as they take water from the mains (rather than a tank in the loft). Changing from a regular to a system boiler can help modernise your heating system and free up some loft space.
To help you decide which boiler type best suits your home, we’ve created a list of the top 10 best boilers for a 5-bedroom house.

Which large boiler is the best choice for your home?
When choosing the best large boiler for your home, it's crucial to consider your property's size and heating requirements. Boiler sizing is primarily about the unit's power output, measured in kilowatts (kW). For larger homes with 5-7 bedrooms and 15-20 radiators, you'll typically need a boiler with an output ranging from 30kW to 40kW.
Despite their compact design, combi boilers can be suitable for 5-bedroom houses, offering central heating outputs of 30.9kW to 35kW and domestic hot water outputs of 38.7kW to 48.9kW. However, for even larger homes with 7 bedrooms, a system boiler with an output of 30.4kW to 40kW would be more appropriate. Regular or conventional boilers in the 30.3kW to 35kW range can also effectively serve larger properties with an installed regular boiler system.
However, compared to regular and system boilers, combi boilers must be more powerful to achieve the same result. This is because they provide central heating and heat the water on demand instead of heating and storing hot water in a separate cylinder.
Overall, the best boiler for a larger 5-bedroom house depends on the number of bedrooms and radiators, as well as other relevant factors such as insulation, window types (such as double glazed windows), and construction materials. To ensure that you select the right boiler for your specific needs, it's advisable to consult with trusted installers who can assess your home's unique requirements and recommend the most suitable option.
