Posting here for traffic, we have moved into a new build and we have an air to water heat pump. We haven’t turned on the heating aspect of it yet as we moved in during the summer and there was no need. We still haven’t turned it on and I’m just wondering when should I turn it on? The house is still very warm. Do I just wait until I feel cold and then turn it on and leave it on as thats what I’ve been told is best to do? I’m so confused.
