hi guys I've been having trouble with my heating for a while basically when the hot waters on the boiler fires up when I use the room control/thermostat it wasn't firing up. My landlord sent round his "plumber" who basically said he's left the boiler constantly in the on position and it will be controlled byy the room stat. So I think ok fine but now ehn I use the stat after a while the flame goe out but the boilers still making noise. Is this normal? Is my heating still going to work? Does it mean its running off the emersion heater?..I went in my loft and didn't see a water tank but my place is a house conversion so I'm not sure maybe downstairs have one and its connected?
