Large houses require lots of power. For houses of 4 bedrooms or more, there will likely be at least 2 bathrooms and multiple radiators to heat. Although there are high power combi boilers, it is likely that for a house of this size you may need a system or regular boiler instead. Our team of experts at Warmable have compared the best boilers, considering type and size, to suit your larger home. For smaller homes, you can also look at our two-bedroom and three-bedroom guides to help you find the best boiler.
What Boiler Size Do I Need for a Large House?
Large homes will need a boiler of around 30-40kW to meet the heating needs of the property. When we refer to boiler size, we’re actually talking about its power or output rating. This is measured in kilowatts (kW).
To choose a boiler size, you need to think about the size of your house. Useful ways to do this include considering the number of bathrooms, bedrooms and radiators in the house. This gives you an idea of how much heating and hot water needs to be generated.
What Boiler Type Should I Choose for a Large House?
Generally speaking, the best boiler for a large house (that with around 4-5 bedrooms and 2 or more bathrooms) will be a system or regular boiler. These boilers rely on hot water being stored in a large cylinder so that whenever you need it, there is hot water ready for use. So, for houses with more than one bathroom using water at the same time, this system is very useful.
However, only think about buying a regular boiler if you already have one installed. Due to the complex heating systems needed for these boilers (i.e. water tanks in the loft, extra plumbing work), you will end up paying a much higher installation fee than necessary.
Upgrading your regular boiler to a system boiler can help to save space in your home and will modernise your heating system, making it less prone to age-related failures.
Combi boilers can be used for larger houses but they generally work better in smaller homes or three-bedroom properties which have between 1-2 bathrooms only. As these boilers don’t have a hot water storage, it can make it difficult if more than one bathroom needs to use water at a time. That said, some models of combi boilers – those with greater power – can provide water for a larger house.
Factors to consider when choosing a boiler for a large house
Power – The key thing to take into account when choosing a boiler for your large property, is selecting a boiler that is powerful enough to meet the heating and hot water demands of the entire property. This will mean a system that can heat not only multiple radiators simultaneously but also multiple water outlets.
Efficiency – heating a large home can be costly so it’s important to have the most efficient boiler possible. The higher the efficiency rating of a boiler, the less energy it will waste as it burns fuel and the lower you can keep your costs on energy bills.

Warranty – warranty is an additional cost. While most manufacturers offer a standard warranty of between 1-5 years, you might decide it’s worthwhile to pay more upfront and get an extended warranty. This will allow for anything that might go wrong with the boiler over the years. The longer the warranty is, the more likely it is that you’re investing in a reliable boiler.
