Heat pumps move energy from and energy source e.g. air, ground water (hence they are called :air source, ground source) to a sink. The sink is the emitter system within a home e.g. radiators, underfloor heating (UFH) and fan coils. Engineers, Installers, designers and the occupants of a home rely on radiators having accurate power output data. Unfortuanlty, it looks like their is a big problem in the radiator industry: the published power outputs are being over stated. This has huge consequences for heat pump systems which rely on designers designing a heat pump system which can operate at ..read more

Here is the link to the heat pump installer survey (lot's of prizes to be won) In this episode Nathan speaks with Glyn Hudson and Trystan Lea who along with open source enthusiasts have created open energy monitor and heat pump monitor. Heat pump installers and consumers are installing monitoring equipment such as heat meters onto their heat pump systems to obtain COP readings. COP stands for the coefficient of performance. The monitoring has provided the oppotunity for engineers and home owners to learn from each other about what works what doesn't work.  Arguably, other monitoring ..read more
