It is a switch, like most heating controllers installed domestically in this country. It's more sophisticated than most of them as well - given it uses learning algorithms, but still all it can do is turn the heating on and off. But given the central room thermostat with timer setup that most...

Not sure the OP even wanted weather compensation. The conversation had wandered since then, I grant you, and I was replying to the most recent post. I was simply pointing out that if you are 90% there with your setp (note the IF), then you may as well go the whole hog. I do agree with your...

I think it depends on the "extra" cost. Also, there seem to be two sorts of weather "control" doing the rounds. There is the internet based type (like Nest and Evohome seems to use) which use the weather information to change switch-on times but can't alter the heating flow temperature. Proper...

True. What surprised me was that once I had chosen the boiler, which was rated to provide hot water to the house (it's a combo), the weather compensating controller was only another £50 or so more than the on/off type room thermostat. Probably paid for itself in six months if not more. I...

No, no, I get what you are saying. You are right. I'm a bit of an idealist.

Yes, fair enough. Have to say that the biggest saving I've observed is through good insulation. My last house (three storey end of terrace 1960s townhouse, with four bedrooms) was £250/month on gas and electricity. There was hardly and insulation and it was a relatively cheap build. Current...

Having looked at EvoHome in the past, and just did the old "design your system" on the Heat Genius page, I'd say EvoHome is cheaper! I'd love to get EvoHome myself but for two things - price (it will never pay back for me) and no windows sensors. Been looking at eQ-3 Max! from a German...

Oh, I don't. Happy with my weather compensating Vaillant 838 with rad valves. Controller lets me run it all the time ("German" mode) and it will sleep when there is no heat loss in the flow. Not that I do. I was just wondering why our regs are so archaic. When condensing boilers first...

A quick question on this. I get that it's part of the regs to have one fitted, and I often see advice that the rad in the room with the wall thermostat should have the valve open (and preferably no TRV). Isn't that a bit... archaic? The temp in one room controlling heating to the whole house...

Sorry to revive this old thread.... i've also been looking at the eQ-3 - mainly for the open window control, to shut a rad off when a window is opened. I have seen one of these (although a Honeywell) in use in Germany. Honeywell don't appear to do that model here, or perhaps they've stopped...
