[QUOTE="Doc Hudson, post: 390216, member: 1607"] Welcome to the forum Gordon. Where about in the country are you? Maybe one of the guys on here is nearby or knows someone local to you. Your problem does sound quite likely to be a valve related issue. The timers and thermostats drive a motor that operates the valves. Once the correct valve has opened a small micro switch inside the valve sends the call for heat to the boiler. When the timers & thermostats are switched off, a return spring should close the valve and disconnect the heat call when the internal switch opens. If the valve is mechanically stuck open, or the switch is stuck on, the boiler will be continually firing irrespective of the timer or thermostat settings. Doc H. [/QUOTE]
