Evohome
Hello, I am having a bit of a nightmare trying to work out what is the best wireless TRV heating controller system or me, and I really hope some-one out there can help me. I have been weighing up Honeywell Evohome and Househeat (whether from Housetech or Conrad). - ?
I almost bought a pack from Housetech, but then decided that I would want a Housemaster / FHZ100 to go with it. Housetech don't sell them and I saw a suggestion somewhere that they don't work very well. Then, separately, I read somewhere on this forum that in order for the FHZ100 to work at all, you need to buy FHT80 BTFN's (sold by Conrad). Not FHT80B, which is what Househeat sell.
My attention turned to Evomhome as possibly a "cleaner" solution. Then everything went pear shaped again. THe more research I did, the more questions I built up. I contacted Honeywell directly to see if they could help me. I got a call from someone there who was not helpful to my quest. She said that Honeywell had released Evohome onto the market in the UK too early, that they had not yet trained the installers throughout the country on how all of the elements of Evohome work together, that she was not prepared to answer my questions because the system is very complicated and I can only have a qualified installer to visit me at my home and specify the installation. But she had no installer name to give me. She said I was welcome to go elsewhere and buy Househeat's product instead ! She said the kit should not be being sold on the internet as no-one understands how to use it, and that its completely different to CM Zone.
So. Can anyone out there help me? I don't have a plumbed zoned system in my house. I probably need 4 zones (over 18 rads). I want a central controller. CM Zone obviously is not preferable for 4 zones. Does anyone have any views on whether the FHz100 sold by Conrad really works (PC Connect would not work for me as I'm a mac user and I don't to get drawn into "slugs"). And does anyone have proper experience of Evohome to be able to give me a view on which bits of kit I need. The following lists the questions that I had put to Honeywell (who refused to answer them).
THank you for any thoughts that will help guide me as to which system to buy (which I'll be building up gradually, not in one go) -
"HI, Are you able to help me on the following> I cannot find the answers in your literature -
Whilst your old CM zone is clear to me, I am having trouble understanding all the Evohome components. Would you be able to help me with what I want to buy?
I have 18 radiators. I will probably want 4 zones and one single overall controller. I would like zone 1 termperature controlled by the Evohome controller and zones 2 and 3 temperature controlled by DT92 room units.
Is it presumably correct to say that I still need the HR 80s for all rads within the zones controlled by the Evohome and DT92's? So I could build up gradually and rely on HR80 control first and then add on a couple of DT92's in the future? And I would always need 18 HR80s, whether I use DT92's or not? Do the DT 92s show current temperature as well as set temperature?
I don't understand which relay box I would need. Why would I choose the BDR91 or the Opentherm Bridge over the HC60NG?
What is the difference between a DT92, a HCW82 and a HCF82?
I have a hot water tank, currently controlled by a typical heating / hot water programmer. Do I keep that programmer for hot water, or add something else onto the Evehome kit. Does the "sundial pack" have something to do with this ...?"
