No not me, - but I did ask for a price from the seller, - no answer yet.
I was looking at installing dual boilers but having decided against dual I dont think I have a need for this unit - although it does interwork with the multi-zone functionality that I could well be interested in. Downside seems to be with the Vaillant control unit pricing
I suspect a better fit to my needs would be from the Honeywell CM Zone units or one of its similar relations as I'm looking for more zones ... http://www.honeywelluk.com/products/Systems/Wireless/
Anyone got any opinions on these?
Evohome is OK but the opentherm part won't work with non Opentherm boilers. Although I've installed a fair number of Evos over the last 24 months, I haven't done an Opentherm one yet, and frankly probably will not be actively pursuing that option.
EvoHome is not really a DIY proposition - Honeywell have enough trouble supporting their Evo trained installers. It is a zoning system rather than a weather comp system.
As suggested above, the likes of Viessmann and Vaillant have some units but the controls are difficult to understand. Worcester Bosch (amongst others) have weather compensated UFH on offer but it is expensive.
