What isa lowtemperatureheatingsystem?Simply put a low temperature heating system operates atlower temperatures to a traditional boiler system.What is coefficient of performance (COP) and why is it so important?The bigger the difference in temperature between the heat source and the heattransferred by the heat pump then the more work (electricity consumed) that the pumpmust do.If the temperature difference becomes too high, it is possible that the heat pump will haveto do so much work that the energy (electricity) it consumes is equal to the energy (heat)it transfers.That is a (COP) of 1.It is important that this difference in temperature is designed to be as low as possible inorder that the performance gain is as high as possible.That is a COP of at least 3.Most heat pumps will perform with a COP of at least 3 when raising the temperature fromthe source to about 45 to 50 deg. C.At greater temperatures, the COP will fall.This means that traditional heating systems that are designed to be operated with aboiler that delivers a water temperature of 80 deg. C will not deliver sufficient heat to thedwelling, if the boiler is substituted by a heat pump (delivering water at 50 deg. C or less).Heating systems that are applied to heat pumps therefore need to be designedaccordingly and are known as low temperature systems..They operate effectively at up to 45 to 50 deg. C. where asa traditional system operates at around 80 deg. C.Ready for the future. Today.1011
