As well as sizing your boiler, heat loss calculations are used to correctly specify the number and size of radiators needed,
or the spacing of underfloor heating pipe and flow rates needed to heat your home to the desired temperature as efficiently as possible.
When purchasing a radiator, it’s important to ensure it will have the correct output to heat your room efficiently.
The manufacturer’s quoted output is based on certain parameters being met.
A radiator with an output of 1039 watts will only do so if central heating water from your boiler enters at 80°C and leaves at 60°C, with a flow rate of only 0.72 Litres per minute.
These temperatures are too high for heat pumps to achieve and although boilers can run at 80°C its very inefficient to do so.
Gas condensing boilers will only condense and meet their advertised efficiency when operating with a 50°C flow temperature and 30°C return temperature.
The outcome of a professional heat loss calculation and heating specification will provide a correctly sized boiler or heat pump, correctly sized radiators or underfloor heating,
running at the lowest possible flow temperatures, with correctly sized pipework and the correct flow rates, and best of all, a warm and efficient home.
