RE: Inventor (Midea) Heat Pump short cycling advice
By immunity, 3 days ago |
|

Yes but... it can only modulate so low. If the demand is less than the min modulation the water temperature will overshoot(heating)/undershoot(cooling) and the heat pump will stop for a while, then r... | ||

I think you’ll find it depends on the room heat loss. A low loss room can be heated by a much smaller difference between mean water temperature and required room temperatures with a moderate sized rad... | ||

DESNZ have engaged ICF to do a survey of people who have had a BUS recently, to find out how satisfied they are with the performance of their ashp. They asked sensible questions like are you satisfied... | ||
