Does anyone know if Vaillant onboard monitoring subtracts the defrost heat taken from the system in the delivered heat or not?
Hello all, does anyone know if the 3.5kW Arotherm+ has the same compressor as a larger 5kW model? All the info on the datasheet I found is identical for the two units.
If they are the same is there any advantage to getting the 3.5kW model over the 5kW model? The main disadvantage I can see with having the smaller one is DHW heat up time.
They’re the same unit, with the 3.5kW being software-limited. Get the 5kW.
Don’t the 3,5 unit have a smaller heat exchanger then the 5 ? The only difference
When I looked they had the same minimal output thats enough to convince me the 5kw is nearly aways the better option.
