Hi,
I've been monitoring the behaviour of my Evohome set-up now the weather has warmed up and I've switched off the central heating. I've set the heating to Off (5deg) on the Evohome so the boiler is only heating the hot water cylinder. I have an S plan and boiler relay set-up with the central heating zone valve removed so just the hot water zone valve remaining. I have the boiler flow temp set to 60deg and the evohome hot water set to 58deg. What I seem to be seeing is that the boiler relay and hot water BDR91s are almost constantly on and the boiler is doing its job and modulating the flow temperature, but holding it at around 50deg. Should I alter a setting on my boiler so that it doesn't modulate its flow temperature to allow the hot water to reach the target temp which should then allow the boiler to switch off until the tank cools to the min of 48deg?
Thanks,
Dan
