    We're Honeywell Connected Specialists ourselves, yet at no point have we ever been contacted by Honeywell to test new systems out, or recommend what could be changed etc. And we've installed a good...

    I understand how Opentherm works and i've fitted Evohome systems with it. Yes it is the way forward and I do think it's a great idea. As i've said Vaillant to an extent have been doing this on their...

    Thanks. No in this case you wouldn't use/require the Vaillant Controller and just use the S/L on the boiler. So it would just be an On/Off and you'd have to set the required flow temperature on the...

    I think that's a bit of a harsh comment. We're always open to trying new things, and i've tried different brands over the years in boilers. Most heating engineers wouldn't even know what Evohome is,...

    Also to save you ruining your new tiles should you ever not use Evohome I stuck my T87RF on the wall with some double sided 3M tape. Means there's no holes should we ever come to remove it!

    No, but how about a HR91 and a T87RF? We have the T87RF in the bathroom and find them particularly useful for turning up the Towel rail before you have a shower to warm towels, then back down when...

    The fact is I chose not to install Atag or Intergas because I don't believe as a whole package they're a good option. I've serviced a few and I don't like them. It's not just a matter of trying new...

    Why are you only running it in the evening? You aren't meant to run UFH for short periods otherwise you won't get the correct heat out of it. In effect you are heating a big surface area that holds...

    Run 3 UFH separate zones off BDR91s and have no issues with them, temperature control is just fine. IMO the HCC80 is a waste unless you have 5+ zones.

    Why would you want to control it with a pipe stat? The idea being it continuously pumps HW round the house during occupied times, I can't see any advantage to temperature control. What I can see is...

    To me it sounds like you've got some form of circulation issue on the cylinder circuit, at a guess it sounds like it is returning too quickly or your pump is on it's way out. It's not a problem with...

    Even when using the standard Stat on the VR66 the flow temperature will revert to the D.078 setting. The Hot water setting on the boiler stays active as it's a software limit, even when just using a...

    You are mis understanding. The 65oc is the temperature of the water in the cylinder. When using the VR66 you have to use the Vaillant NTC probe into the cylinder. This then measures the temperature...

    The 65oc is the temperature of the water not the flow temperature, not sure why anyone would want it any hotter than this? I find 55oc too hot at the taps.

    Even with that system you would still be able to have HW and CH at the same time as there's no software HW priority in Evohome. Are you sure it's not a binding issue and something is mis bound?
