My central heating is costing a fortune to run. 3 bedroom mid terraced house, 4 people - Â£150+ per month in gas being used!
I've had leak seal put through the system. Pressure drops if I put heating off and just leave hot water on. Now when i go to repressurise, I turn the fill loop and can't hear the water rushing in and it takes around 20-25 minutes to get pressure to 1.5br.
Also there's a constant sound when my heating is on, like water running through the system and the pump seems to go continuously.
Any help greatly appreciated cos I can't afford these gas bills anymore!
