Hi all,
I have recently bought an Evohome system for my house, which I installed myself in the end, after receiving a quote for over seven hundred pounds from a plumber, which I didn't think was fair, for what he admitted was less than a day's work. I didn't find it too tricky, on the whole, once I got over the fear factor of tinkering with my boiler's innards.
It's a pretty bog-standard setup, of 7 HR92s, grouped into 6 zones, and a BDR91 wired into a combi boiler. The only issue I have is that, due to what I presume to be slightly outsized pins on my radiator valves, I had to leave the HR92s a turn or two from being fully tightened. I discovered that when fully tightened, the HR92 was unable to open the valve, as the pin was fully depressed, even when the black wheel was turned fully anti-clockwise. Unscrewing the HR92 a wee bit alleviated the issue, and the system seems to work extremely well, with actual room temperatures closely following my programmed targets.
I was wondering if having to leave the HR92s was likely to lead to problems, and whether I should perhaps grind a few mm off the valve pins, or even replace the valves?
