Frequently asked questions
What is the lower limit operating temperature?
-20°C is defined as the lower operating limit but the heat pump will not switch off at this temperature. if the heat pump is expected to operate below -5°C for long periods of time then a boost heater should be fitted to act as a backup. At -20°C the maximum supply water temperature will be 45 C.
What controls will the heat pump work with?
The heat pump is fitted with a controller that is pre-programmed with all of the operating set points and alarms and simply requires an input from an external clock/thermostat. Any standard type of central heating controller will work with the heat pump but the best solution is to use a controller with a number of on/off options for each day to take advantage of any special off peak tariffs available.
