What size boiler do I need? Try our power calculator

When calculating your boiler size, you might notice two powers in the specifications of a given boiler. One is the power input, the other is power output. Input says how much energy goes into the boiler to make it work, and output says how much of that energy is converted into usable heat. Efficiency is the percentage of output from the input.
