Best boiler for a 1 bed flat

No matter what size your home is, it’s essential that your heating system is suitable for your needs. A boiler that is too powerful could cause unnecessarily high energy bills, whilst a system that’s not powerful enough could leave you without the heating and hot-water you need.

Here at HomeServe, it’s our goal to help you find the ideal heating system for your home. We install a range of boilers from leading brands, and our team has the skills and knowledge to provide you with expert advice. Below we provide all the information you should need to select a suitable boiler for your 1-bedroom flat.

Choosing the best boiler for a 1 bed flat


Boilers are available in a range of different sizes, so we understand how confusing it can be when trying to select a suitable model for your home.

One of the main aspects that you’ll need to think about when making a decision about boiler size is the kW output that your home is likely to require. kW output can be described as the size of a boiler and dictates a system’s ability to deal with your hot-water and heating demands.

The higher the kW output of a boiler, the higher the demand for central heating it can tolerate. The kW output required for your home in particular will depend on the number of radiators and bathrooms within your property.


Could a combi boiler be best?


If you’re looking for a boiler for a 1-bedroom property, we recommend getting a combi boiler installed. Combi boilers are highly efficient systems that are able to provide both hot-water and heating all through one compact system. No additional tanks or cylinders are required, so they tend to be a great choice for smaller homes.

To give you a better insight into combi boiler kW outputs, we’ve provided an estimated guide below. The table below displays different outputs and suggests the types of homes that they are typically suitable for. As per the guide, the central heating demands of a smaller, 1-bedroom home with up to 10 radiators and 1 bathroom, could usually be met by a system that has a kW output of between 24-27 kW (this can vary depending on your heating demands).


24-27kW 1-2 bedroom, 10 radiators, 1 bathroom
28-34kW 3-4 bedroom, 15 radiators, 1-2 bathroom
35-42kW 4+ bedroom, 20 radiators, 2+ bathroom
