      Water Heating Calculator for Time, Energy, and Power

      How do I calculate btu size for heating a swimming pool? I’m looking at a 50,000 btu boiler with a heat exchanger to heat a 33,000 gallon pool to 90 degrees f. I’ve run then calculation through the formula above, and it’s coming up with a 600,000 btu boiler to raise the water temp (68f) in 5 hours to 90f, which seems to be a really high

      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.

      Calculating heat required for Domestic Hot Water Systems

      Estimating for the domestic hot water supply. Where the central heating boiler also heats a tank of domestic water supply, the boiler needs to be sized to include keeping the tank full of hot water while not disrupting the hot water for the central heating. This does not apply where a Combi Boiler is installed as no hot water storage is involved.

      What size of boiler do I need for my home? | Viessmann

      System boilers and conventional boilers preheat hot water to be stored in a hot water cylinder and therefore hot water flow rate is not as critical. The heat load for an average home can vary from around 10 kW to 20 kW, which means that system boilers and conventional boilers can be sized lower than combi boilers.
