Ecodan heats water only to 39C with heat pump in warm weather
My Ecodan only heats the DHW (Domestic Hot Water - in the boiler) to 39C by using the heat pump while it is 30C outside. I have to use the immersion heater (= pure electric) to increase the temperature further!?
My installer tells me that this is normal, because heat pumps are designed/optimized to work in moderate temperatures.
To me this sound not very logical.
I've read the user manual, service manual, but did not find useful/relevant information.
Who can help me?
