[QUOTE="Barx, post: 533053, member: 121"] Like I say, I'm probably using the wrong term. I understand what you are saying, but the system I was on about is gravity circulated. i.e the hot water from the boiler heats the hot water tank coil through the force of hot water rising above cold water. There is no pump of valve connected to this part of the system. Hence you cannot isolate the Hot water and just have heating only. It's how the old coal fires and early back boilers were plumbed up. then they started adding valves for extra control. That and the fact the hot water tank would sometimes 'kettle' from the coal fire and no way of turning it off :ROFLMAO: Surely you remember the old mechanical clocks that had the switch on the side for 'hot water only' - 'off' - 'heating and hot water' [/QUOTE]
