Hello I have a closed unvented heating system that loses pressure very regularly. I am having to top-up the system via the filling loop every 2 to 3 days to 1 bar, then it's down to zero when I top-up again. The tundish on my system was discharging recently and a pressure valve was replaced...

Hi, When turning my hot water on, i notice the radiators also get heat. I've checked my system and i believe it is an S Plan system as i have 2 2-port motorised valves, one for water and one for heat. When my programmer calls for heat or water i can hear the noise from the motors and the...

Hello all, I have a radiator in the house that is hot at the top and cold at bottom. Seems most likely cause is sludge or dirt in the radiator so i've taken the radiator off and hosed it through which a lot of dirt came out. I've put it back on but still i have the same issue, is it likely...

Hi all, I've just had a water meter installed and now the water flow in the house is very slow, seems to be affecting both cold and hot. The heating system is pressurised and i have the Zilmet Ultra-pro vessel. I'm wondering if there was some pre-cautionary measure that i should've taken...
