Following the replacement of a gate valve next to pump and draining off the system (this all worked well) and all back as normal....But however i cannot control the amount of HOT WATER as the cylinder thermostat has no affect on the temp. (set to 45 deg...getting up to 75 deg heat )
I have replaced the stat in an attempt but heat still ignores the setting!!!
p.s. turning the dial still trips it on and off but when left, level rises above setting.
please help
