Whether you live in a 3-bed bungalow or a 3-bedroom terraced house, choosing a boiler that is able to meet your needs is essential. There is an abundance of boilers available on the market, so we understand that choosing the right one could be a difficult task. However, here at HomeServe, it’s our goal to ensure that you get the right boiler for your needs. Read on to find out all you should need to know about boilers for 3-bed homes.
Choosing the best boiler for a 3 bed house
It’s essential for your boiler to be an adequate size for your central heating demands. A boiler with too much power could cause you to have unnecessarily high energy bills, whilst a boiler with an output that is too low could fail to provide you with the heating and hot-water you need.
At HomeServe, we aim to provide our customers with a boiler that not only has the power to deliver effective central heating to their home, but also has the efficiency to help them save on their energy bills*. We install heating systems from some of the leading brands in the industry, so you can rest assured knowing that with us, you’re in safe hands.
What size boiler is best and why kW output is important
The main thing that you’ll need to consider when debating boiler size is the kW output needed for your household. kW output can be defined as a measurement of a boiler’s power and its ability to cope with your central heating needs. Generally, the higher the demand for heating and hot-water, the higher the kW output needs to be. The kW output required for your home tends to relate to the number of bathrooms and radiators present.
The kW output needed for your home will also be influenced by the type of boiler you choose.
There are 3 main boiler types:
The kW outputs for these boiler types are measured differently. Here's some more information on these boiler types along with estimated guides of their kW output ranges:
These systems are designed to be highly efficient sources of central heating. Capable to delivering both hot-water and heating all through one compact system, you could enhance the levels of efficiency and save space in your home with a combi boiler. Take a look at our combi boiler page to find out more.
To help you get a better understanding of combi boiler kW outputs, we’ve created the following estimated guide:
|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|
Also known as regular or heat only boilers, these systems are regarded as a traditional form of central heating. Using an additional hot-water tank and cold-water cylinder, these systems store water and deliver it to your taps and radiators when needed. Visit our page on conventional boilers to find out more about this boiler type.
System boilers are designed to provide heating and hot water, similarly to a conventional boiler, however they do not require a water storage tank. They are normally located in the loft space. You can find out more about this boiler type by visiting our system boiler page.
To help you select a suitable size for your 3-bed home, here’s an estimated guide of both conventional and system boiler kW outputs:
|12-15kW||1-3 bedrooms, 1 bathroom|
|18-24kW||3-4 bedrooms, 1-2 bathroom|
|30kW+||4+ bedrooms, 2+ bathroom|
