RE: New ASHP system - choices

@mattc The heat loss was done for a temperature of -2.5°C and produced a figure of 7.31kWh for heat loss. That would work out at 175kWh for a day a...

RE: New ASHP system - choices

You would think/hope that energy used in heating a building would be an ideal benchmark to build a system round, but unfortunately it doesn’t seem to ...

RE: My ASHP is not performing as well as I’d hoped: COP just over 2

@hcas - exactly so. I did read one other persons similar experience but the overshoot was lower if I recall correctly. I can only make this comparison...

RE: Ecodan - optimal external installation?

I think this notion of an 'optimal' install is something of a chimera. Every installation is different, and the majority of forum users have experienc...

RE: Why are my estimated delivered energy values so much lower than my consumed? (Mitsubishi Ecodan)

The last picture is the flow meter, the other two are of the tank thermistor in its pocket. The flow and return thermistors should be on the main pipe...

RE: Why are my estimated delivered energy values so much lower than my consumed? (Mitsubishi Ecodan)

I would look first at the placement of the thermistor measuring the flow temperature. I am going to assume you have an Ecodan cyclinder too, in which ...
