Yes, that's what I was getting at.
Apparently 'optimum' room temp should be 18C . . . but whatever (water? oil? ) is running around in those pipes & radiators needs to be quite a bit hotter.
Probably fine if it's on constantly, as it would take a week to warm up from scratch
Do installers still recommend an emersion heater along with the heat pump?
