We have a 2 year old Valiant EcoTec 832 Combi boiler which was running our CH and hot water.
We recently had some UFH installed and the boiler moved to our new extension.
Over the past weeks the pressure in the heating system keeps creeping up. It goes from approx 1.5 to 3.2 bar overnight. If I do not drain any of the water out it remains at approx 3.2. When I drain the water to bring the pressure back down it creeps back up by the next day.
I have checked the filling loop valves and they are all in the off position.
One plumber suggested (over the phone) that we would need an expansion tank fitted as the pressure rise may be due to the installation of the UFH system?
Is this correct or is it more likely a fault somewhere?
Thanks!
