For a 4 bed house, the optimal power output range is between 18 and 34kW. Finding the best boiler for your home doesn't mean only looking at boiler models and price ranges. One of the main things you need to consider is your boiler’s power output. 

Exactly what power output you’ll need depends on whether you’re getting a combi, regular, or system boiler. Additionally, the size of your home and the number of radiators you have will directly impact the output size you require from your boiler. For a clearer idea of what size boiler is needed for a 4 bed house, you can check out the video below:

Of course, because your situation is unique, it’s best to consult a boiler installer to determine the right boiler size for a 4 bed house.

Overall, regular and system boilers are the best choice for larger homes with high heating and hot water demands. This is because they can provide consistent heating and supply hot water to multiple taps at the same time. 

Combi boilers, on the other hand, cannot attend to high energy demands quite as easily. As a result, they are typically a better option for smaller homes with fewer radiators and bathrooms. 

If you do decide to install a combi boiler in your 4 bed house, it’s important to consider that you’ll need to choose a model with a high power output (higher than that of a system or regular boiler) to ensure optimal heating for your home.
