Not to hijack the thread but a little more info on hydrogen here: https://www.carbonbrief.org/in-depth-qa-does-the-world-need-hydrogen-to-solve-climate-change
FWIW my experience is as DB describes. My load scaling has been set at "normal" for some time and it's noticeable how much smoother things feel and how much less boiler activity there seems to be....
Thank you for posting Bruce. The problem was of my own making in that I'd placed a temperature sensor a couple of feet away from the display a fortnight ago to check whether I needed to change the...
My system has worked largely flawlessly for two years now.
Brief overview: one BDR91 that switches a UFH zone and one that operates the rest of the rads which are all contolled by HR 92s.
Today...
Given that the sum total I've learnt about Evo has come from you and others on this forum, anything even trivial I can offer may just be of a little help to someone else in future. The few hitches...
Hi
This says more about me than any deficiency in the Evo system but I'm posting just to save any other potential headscratching. I was changing the batteries in an HR92 and following the...
Hi
I apologise for my late response but have taken the time to be away with others while I can. From memory, the batteries were typically reading around 1.54v under no load.
We returned yesterday...
Sorry I can't help directly but I'm having an analogous issue. My kit has been fully installed for 23 months and the original batteries are now starting to fall over like dominoes. I guess I may...
I'd be thoughtful about that. My boiler apparently has an ABV but, as belt and braces, I use a large towel rad as a bypass in case of pump overruns.
The bonus is that towels are always bone dry.
Thanks Andy, update received. Cold weather boost, warm weather saver and load scaling all installed with default values (where offered) accepted and applied across all zones.
My boiler model wasn't...
Ditto - great to see.
Quite an interesting one and so many variables of course, depending on insulation, room size etc.
Taking out pipe runs and associated heat losses, added cycles on the boiler and so on, I suspect...
Yes, as with the others, thank you for posting Rameses. It's reassuring to hear that EH is still in development and I too am fascinated by the zone scaling and the prospect of satellite add-ons to...
Is it showing optimised start? Not sure where an explanatory list of symbols might be though.
I started out with my wet UFH plumbed into a radiator circuit but was never completely happy with its controllability. I know in theory that it should be independent and fine if all rads have HR92s...
Hi Evo -user. I wondered whether for some reason your top floor TRVs were a different model from others you have and perhaps needed adaptors. By valve body I meant what's left on the radiator when...
Are they mounted cleanly with the locking lever in place? Also are the valve bodies the same as are in zones which respond properly?
Thank you Philchillbill and G4RHL, you've reassured me on the 868 front. I'm a bit put off further Evohome investment given HW's apparent disinterest in their existing customer base.
Hi
Apart from the well noted unreliability of accessing Evohome remotely my system seems to be running very reliably. One of my concerns before installing was about signal reach but it has proved...
Others here are way more expert than me but I don't understand your question in that I would expect Evo to call for heat if zone(s) are below setpoint. Apologies if I've misunderstood your question.
Hi Anthony - not sure of your fuel source/ boiler cycles per hour etc but do you think this may be just the boiler dissipating heat through a bypass via pump overrun especially when all 6 valves...
Yes the ability to access and monitor the system while away was a key feature that took me down the Evohome route. In fairness I've been lucky enough to find things operative on the occasions I've...
Hi Woodburner - When I originally installed my UFH I too installed it as part of the radiator circuit. It worked yes but the benefit of Evo was negated in that it was awkward to target the heating....
I confess I'm pretty much 'non-techy' but find DBMandrake's explanation of the wireless protocols absolutely compelling - thank you!
Am I right in inferring that it's maybe preferable to avoid...
