At what temperature should I turn my heat pump off?
Just out of curiosity, at what sort of outside temp should I turn my ASHP heating off? We are set for a week of plus 10 degrees, windy and wet. Would it save me enough over a week to turn it off then back on as temps drop or is that just a massive no no?Â
I have a gas fire that I can pop on to keep the warmth in the evening if needed but we both work outside all day so don't like a mega warm house anywayÂ
Also, do I turn it off once spring arrives?Â
Upon googling all I can find is that I should turn it down even in summer but not off. 🤷
I understand that it runs best when constantly on for long periods at low temps but I assume there must be a balance point.Â
Thanks again.Â
You'd definitely save money by turning your heating off for a week! I just leave mine on all the time. The weather compensation makes sure it doesn't come on when it's too warm. Even if it does, it's not using much energy. I wouldn't bother for a few days at a time. Some ASHPs consume a significant amount even when not heating so it may be worth turning these off for a few months over summer.Â

Hi Craig,
There is nothing to lose by giving it a try. I agree with Kev, if you don't need the heating for extended periods then it may be preferable to switch it off, but don't do so if there is any chance of unexpected freezing conditions.
I would check how much gas, if any, that you use when your heat pump is switched off.
