Do you have a heat pump on http://HeatPumpMonitor.org with MID meters? If so, we need your help to compile real-world maximum output test data. We’re working on creating an open-source database of real-world heat pump maximum output and minimum modulation data, this will be very useful to ensure heat pumps are correctly sized: https://heatpumpmonitor.org/heatpump
Watch the video below for how to contribute. There should be some cold temperatures tonight and tomorrow. Thanks!
