What heating elements or output temperature are you runnng your HP at, and do you have buffer storage or not?
- bobchadwick 3y agoIt's an air-air ducted system. I live in the North East US, so winters are generally cold, with a few days around 0F/-17C. During heating season we keep it at 67F/19C.
- petre 3y agoThat's a COP of 2.8. You have to check the efficiency graph and your mean winter temperatures, because I suspect it operates fully resistive at below -10°C or so. I also noted underwhelming performance and increased faulty compressor incidence for air source heat pumps with the external unit mounted on Northern walls (in the Northern hemisphere). I suspect it doesn't get sunshine and the defreezing resistive element is operating a lot, driving up energy costs.
