Hi,
We have a Valiant system boiler and water tank installed several years ago following a large home renovation to our 5 bedroom house. An Evohome installed with 3 zones including a UFH using a room stat on each floor. Our gas bills usage is showing at the moment nearly 234Kw per day (approx £8.30 a day...£252 a month!).
I'm now at the point where I am trying to understand where the gas is being used. So now watching the smart meter for when gas is being used (only the boiler is our gas appliance, everything else in house is electric based). At the same time watching the honeywell evohome that tells me which zone is calling for heat.
What I originally observed is even though there is no demand from any of the zones, there is gas being used according to the smart meter. When I go to the boiler I can hear it switched on and even for 20 minutes or so its going through a series of status symbols from "egg timer" flashing, "radiator" flashing and then "radiator" solid. All pipes are cold apart from the hot water feed to the tank which is hot.
So reading up there was a suggestion that maybe the problem is a sticking value on the hot water that is keeping the boiler running. I "tapped" the motorised valve to see if that helps (sticking valve possibly?).
Normally we have the hot water to be on each morning from 5-6am. But as an experiment, I turned off the timer also however I've noticed over the past 3 days now we still have hot water showing from 61 to 64 degrees (according to the evohome controller screen). Is it possible that heating radiators also will by default warm up the hot water????
I do notice that even when there is no heat demand, the boiler still sounds like its on?? could it be that it using Gas but not supplying heat anywhere???
Sorry for lengthy question.....looking for some answers!
Thanks in advance.
