Hi all, I had my boilermate 2 replaced few months back with an advanced appliances thermal store (TSDC140). It's been working fine up till now but over the last few days I've noticed the boiler firing up a lot and our gas usage increasing. I've checked the metal F&E tank and its full of very hot water! I've listened to it whilst the boiler is running and the heating on and can't hear any water coming into the tank. All rads are heating up normally on request, the cylinder stat on the store operates and switches off the boiler when up to temperature. Any ideas or pointers welcomed. Thanks.
