Hi,
I’m having issues with my heating that I can’t seem to figure out. So live in a small one bedroom flat on the first floor and have a split system air source heat pump with underfloor heating. For some reason my flat gets extremely hot at night time. It gets literally unbearable during the summer months even when I have Windows wide open and fans blasting. This only ever seems to be at night time around 4pm and gets worse around 6pm. My thermostat is set to standby as shown In pictures and my boiler has been to cool, not sure if it makes a difference but tried it anyway yet my flat always heats up night. Could this be an issue with my underfloor heating? There is no schedule set for it to come on at all as it’s set to standby all the time. It’s nothing like heat coming from consoles or tv either as I can be out all day and come home at night and the flat Will still feel like a sauna. Also my energy bill is getting ridiculously high even though my heating is never on so I’m wondering if there could be a fault with my heating that’s running up my bill and causing flat to heat up at night.
