The size of an electric boiler is measured in kilowatts, which is a measurement of power instead of the actual size.
To guarantee that you install an electric boiler that can meet your home's need for heating and hot water, follow the instructions in this guide.
So, what size do I need?
The power output of boilers is measured in kilowatts (kW), and it helps to determine how much heating and hot water the boiler can handle. To put it another way, the higher the kW rating, the more radiators and taps it can provide at the same time.
Electric boilers aren't extremely powerful, therefore you won't find them with output ratings much greater than 15kW. Boilers made of gas or oil, on the other hand, can have substantially higher output ratings, making them more suited to situations where heating and hot water demands are higher, such as in larger homes.
Here at AllForProperty, we recommend adding 1.5kW per radiator in your home. So, if there are eight radiators, a 12kW electric boiler will suffice for central heating.
What happens if the electric boiler I choose is the wrong size?
If you install a boiler with a low output rating, the boiler will struggle to meet your home's heating and hot water needs. Similarly, if you install an electric boiler that is overly strong, your energy bills would quickly skyrocket.
This goes for many boilers, not just electric boilers, making it very important to select one with the best output rating for your home.
If you're uncertain about the boiler size you'll need for your home, the best thing you can do is hire a heating engineer to come out and inspect it.
