Hi chaps ,

 

reading this ..

https://kronoterm.eu/how-to-set-up-your-heat-pump-for-maximum-comfort-and-minimum-cost/

 

 

i saw this bit ..

ashp leccy heaters .

 

 

i know there are lots of different makes of pump , but i wonder , is this a thing that most pumps do , meaning if , as i do , i run my pump at hs temps of 15-16c , i am possibly then using more kw than i would running it at 20c !

 

that would be an eye opener and no mistake .

 

 

regards

robert

As per the screen shot, when my Ecodan is not calling for heat and is effectively 'off', you will see that the flow and return temp' is always at a minimum 20c.

Thanks morgan , i can't find any flat bits in my graphs ..

Heat Pump(9)

probably because i suspect  its about 6x too big , i can see looking at the amps line , there don't sem to be any spurious power surges in between cycles .

Interesting because when my Mitsu is not running I recall typically Phase A shows zero; Phase B 11.2W & Phase C shows 107.44W.  I thought it was the control plus the undesirable secondary circulation pump. It doesn't seem much for any electric heater on a 16kW ASHP

i agree david , that sounds like a water pump sort of draw.

maybe its just that ashp make in the article that does it ..
