      A hot water boiler is sized by the number of BTUs per hour that the boiler will supply (output). Smaller boilers — those producing under 200,000 BTU/hr — are usually called water heaters rather than boilers. An alternative to a boiler is a thermal fluid heater. Thermal fluid heaters are sized by the number of BTU/hr that the heater will

      AFUE and Real Boiler Efficiency | Annual Fuel Utilization

      Typical boiler efficiency is routinely much lower than AFUE or combustion efficiency, especially for cast iron boilers or boilers with high “mass” and less than 2” of insulation, and for boilers that finish above 120°F when the thermostat is satisfied (AFUE rates boilers with a 120°F return temperature, but they typically run with a 160°F return and 180°F supply).

      A solar thermal system will produce a lot of hot water in a short period of time, then none for a long time. So the storage vessel needs to be big — 300 to 400 litres. A thermal store will typically be 200 to 300 litres, which is a happy compromise for the typical family, allowing for both traditional and renewable heat sources. Thermal Stores
