There’s a lot to think about when it comes to choosing a new boiler for your home. One of the most important factors to consider is the output size. If you’ve stumbled across this article then you likely already know you need a 28kW boiler for your home. However, if you’re still not 100% sure that’s ok! Here is a guideline you can use to see which output size is likely suitable for your home:
|No. of Radiators||Combi||System||Heat-only|
|Up to 10||24-27kW||9-18kW||9-18kW|
|Up to 15||28-34kW||18-26kW||18-26kW|
|Up to 20 (and over)||35-42kW||27-40kW||27-40kW|
But as you can see from the table, output size isn’t the only factor you need to take into account when buying a new boiler. You also need to consider which type of boiler (combi, system, or heat-only) you’d like as well as the efficiency rating and warranty length.
That’s why it’s important to compare multiple 28kW boilers to make sure that you’re getting the one that best suits your needs. In this article we’ll talk you through what some of the available options are in the UK.
Another crucial element to compare when buying a new boiler is the price. However, researching and contacting installers one by one to try and figure out their rates can be a tedious and time-consuming task. Thankfully, GreenMatch can take this burden off your plate!
