Posted By: GaryBIn winter it is cheaper to run an ASHP at 45 deg C and top up using an immersion heater than to run the system at 55-60 deg C to heat water.
Posted By: GaryBAverage COP = (0.7 x 3.2) + (0.3 x 1.0) = 2.54
If anyone can produce evidence of an ASHP which can produce 60+ deg C hot water at a COP of 2.54 or better with a nominal external ambient of 7 deg C
Posted By: SteamyTeaThis is where the entropy comes in. You need that 1kW (or whatever you need) to be at least the final temperature.You can have as much energy as you like, but if it just heats to say 30°C. not going to be very useful.
