How Do I Know Which Boiler I Need for my Three-Bedroom Home?
The size and type of the boiler needed for a home will depend more on the number of bathrooms than the number of bedrooms. A 3-bed home in the UK will typically have between 1 and 2 bathrooms. Generally speaking, the best boiler for a three-bed house will always be a combi boiler, offering a balance of space efficiency, convenience and enough power for the whole house. If you have more than two bathrooms, you might be better off choosing a system boiler to cater for a higher demand for hot water.
Why is a Combi Boiler Best for a 3-Bed House?
For a 3-bed house, the combi boiler is the perfect choice. It features everything it needs to heat your entire home as well as the hot water inside the boiler. Unlike system and regular boilers, the combi boiler doesn’t need any external parts such as a tank in the loft or a cylinder. As a result, a combi boiler is one of the most space-efficient options for a 3-bed house.
How Does a Combi Boiler Work?
When you turn the heating or hot water on in your three-bedroom home, the combi boiler will heat water directly from the means. This allows the hot water to travel to the hot water outlet or two radiators, providing instant access to hot water. Unlike alternative boiler types, you don’t have to wait for the cylinder to fill up again.
What Boiler Size do you Need for a 3-Bed House?
Whether you are choosing a combi, system boiler or regular boiler for your three-bedroom home, you will need to choose a boiler with a sufficient output size (measured in kilowatts) to heat your home. If you opt for a low output size, you run the risk of poorly heated radiators and not enough hot water coming out your taps. Choosing a size that is too high for your home will mean overpaying for your boiler and monthly energy bills.
Our boiler experts tend to recommend a size of between 28-34kW for a combi boiler in a three-bed house. Depending on the type of house you have, you might choose a lower or higher kW capacity. For example, flats and bungalows will only need a combi boiler of 28kW, whereas detached or semi-detached homes of a greater size may benefit from a 34kW combi boiler.
If you are choosing to opt for a system boiler or conventional boiler, you can choose a size of between 18-26kW.
How much central heating output does my boiler need?
| House Size | Combi boilers | System boilers | Regular boilers |
| 3-bedroom house (around 6-8 radiators) | ~ 18kW | ~ 13kW | ~ 13kW |
For larger houses, which will need a greater size capacity, we recommend reading best boilers for a large house or best boiler for a detached house.
The central heating for most three-bedroom homes should sufficiently heat at least 6-8 radiators
