Why are combi boilers best for smaller homes?

small homes

If you’re looking for a new biler and you have a small property with one bathroom and less than ten radiators, you will be able to get more than enough heating and hot water from a gas combi boiler. 

The compact size of a combi boiler makes it ideal for a small home. As you do not need to have a separate water tank, a small combi boiler system will take up much less space when compared with a traditional heating system and other types of boilers. This makes them perfect for properties with limited space.

If you live in a small property, a regular or system boiler probably won’t be suitable, as it is unlikely that you will have space for a hot water cylinder. If you want to check out boilers for 3 bedroom homes, try here

How to choose the right boiler for your home

You need to consider many factors when looking for a new gas boiler for your central heating system. if your boiler is leaking or decided to break down so your boiler’s not working at all, then hopefully this guide will help

You need to consider the size of your property, how much hot water you and your family use, the fuel you have available, and your current central heating.

So, let’s take a look at how to choose the best gas combi boiler for your needs:

boiler size image

Boiler Size

Boilers are measured in British Thermal Units (Btu), which refers to the amount of energy required to increase a pound of water by one degree Fahrenheit precisely. 

You can figure out your home’s Btu requirement based on where you live, the size of your property, how well insulated the building is, and the number of windows and doors you have. 

If your boiler is not the right size, it will either overheat your home and waste energy or it will not heat your home adequately. Use our boiler size calculator to help.

Venting requirements

Consider the venting requirements when searching for a boiler, and make sure you can meet them. If you do not have anywhere to vent your boiler, it is going to be useless. 

You can vent some boilers via your chimney, whereas others will need to push used air via a vent in the wall. 

boiler energy efficieincy


A boiler accounts for approximately 60 percent of CO2 emissions for properties with gas central heating. So, if your boiler is inefficient, you are going to waste a lot of energy and your utility bills will be high.

Look for an A-rated high-efficiency boiler, which could save you as much as £300 per annum

A boiler with an effective heating control system is critical for efficiency, as it means you can determine which rooms you are going to heat and when. As a result, you can stop energy from being wasted.

Roughly 4.3 million UK households are not on the gas network. There are plenty of alternatives to natural gas, such as LPG, wood, and oil. 

There are pros and cons associated with all fuel types, so consider this carefully when looking for the best option for you. We have pointed out that hydrogen ready boilers are the future too to use hydrogen as a potential fuel source.

LPG is widely considered the most efficient. It also has the lowest carbon emissions in comparison to other fossil fuels. Plus, there is less soot and lower sulphur emissions.


So there you have it: everything you need to know about choosing the perfect boiler for your two-bedroom home. 

We highly recommend purchasing a combi boiler for a two-bedroom property. Combi boilers are very efficient and they are compact in size as well, making them ideal for homes of the smaller size.
