    We leave ours on 24/7 in Winter and Summer. The Evohome calls upon it whenever the radiators call for heat.

    A buffer tank, or thermal store, is a large cylinder with multiple tappings that allow...

    I have a similar arrangement with a Windhager boiler. It controls the loop between the buffer tank and itself and the Evohome system is the other side of the buffer. It works well and doesn't need a...

    Just a couple of questions for Rameses:

    Are the HR92's fully proportional, or are they controlled in stages? i.e. will they go to any point between fully open and closed, or do they just have a...

    Not sure if anyones asked for this so far?
    I'd like to be able to simply set all zones at the same temperature.

    I find these discussions quite fascinating. I think that we have two different worlds here, the old analogue one with a digital overlay and the demand for a very precise digital control of something...

    We installed Evohome in December at the same time as switching from oil to wood pellet, so it's difficult to compare costs. But as others have said, you do tend to crank the heat up further in the...

    Yes, the green light stays on until the pump shuts down. I'm turning the system off by using the quick action "heating off'. I've set it at the maximum cycle rate and minimum run time (12 and 1...

    Bypass with Alpha Pump

    I have a sealed CH system with an Grunfos Alpha2L pump. There are TRV's on all radiators but no bypass fitted. I'm wanting to fit a Honeywell Evohome system and am realising that I probably should...
