Is my air sourced heat pump working correctly?
Hi all so purchased a 5kw sunspring and had it on all day yesterday.
Yesterday morning put it on, flow coming in was 13.2c, ran in all day and checked before I went to sleep was 16.4c.
Now the outdoor temp yesterday was pretty cold I’d say around 12c.
Overnight it dropped and when I woke up the outdoor temp was 3c with the heater dropping slightly to 15.8c.
So from 10pm to 7am the temp hadn’t increased? Is this normal when it’s so cold outside? , I assume it was just battling the dropping temps.
