I’m having problems with my Evohome controlled CH.
Basically I have a hybrid system that was installed by my builders plumber when we had the house extended and a new boiler installed.
I really just wanted a smarter way to control my room stats but now realise that the Evohome is more complicated than that. My wife works from home so we want the heating on all day, but only the downstairs heated during the day.
I have the Evohome controlling the CH with programmable radiator valves, a separate conventional Honeywell programmer controlling the HW, and a John Guest UFH system for 2 rooms all off the same Worcester Bosch boiler.
The HW and UFH are working OK but the rads are not heating up despite the Evohome controller showing measured temp as lower than demanded temp.
This seems to have got progressively worse in the 4 years since the system was installed. It may be something a simple as the CH valve, or may be the Evohome system itself. I’ve got a local heating engineer coming around to check the system, but he won’t touch the Evohome.
So I’m considering disconnecting the Evohome from the CH completely and just running the boiler from the conventional programmer, and try using it just as a valve programmer. The alternative would be to buy a newer Evohome that now supports more zones and move the complete system over to the Evohome. However, given my experience to date I’m loath to do this without specialist help.
I’m getting pretty frustrated by the whole thing.
