    VENTED central heating system - water circulating through header tank

    Two years ago, I requested a fully qualified plumber to change the location of the hot water cylinder in a vented central heating system. I wanted to move it from the first floor to the loft, which he did. During the last two years, I have often noticed when I have been up in the loft that the...

    I'm planning on replacing a living room back boiler (in a fire place) with a 22kw multifuel stove. The stove will complement an existing oil boiler and feed the radiators serviced by that oil boiler and also occasional heating the living room without turning on the central heating. Back boiler...

    Hot water in the loft header tank

    1st post. I have a gas C/H with a gravity feed to the hot water secondary circuit. Several times a day I hear bubbling/gurguling sounds (that may coincide with the room thermostat demanding heat). Checking the C/H header tank in the loft, I can feel that the tank is hot. There is a pressure...

    Hot water running from CH header tank overflow

    Hot water is trickling from the header tank overflow pipe only when the CH is running. It is a dual system (CH or hot water with motorised valves) and no drip occurs when only heating the hot water. No drips either when boiler is off so the ball valve is OK. Now my small 2 up 2 down house only...

    Hi, about to replace some radiators, so need to drain system. While i'm doing it I'm thinking about doing a mod to make future drain downs quicker: Idea is adding a gatevalve on header tank outlet, and just below the gatevalve add a tee to a pipe that goes up to above tank level with another...

    Central heating header tank seems to be overflowing...

    Can anyone advise... I believe it is the central heating (for radiators) header tank that is overflowing from time to time - ie once or twice a day for a few minutes (it appeared to start again today shortly after the central heating came on - and then the pouring/dripping stopped after a few...

    Hot water 'back flowing' to header tank

    Hi all, Sure this has been answered many times but can't quite see previous post which covers this. I'm not a plumber which will likely become obvious! :D So, currently suffering from constant run-off from F&E overflow into garden - moderate flow, like a tap is on! The F&E tank is filling up...

    dripping overflow on header tank

    Hi, When my central heating has been on for a bit the central heating header tank overflow is dripping about one drip every second or two. Not such a problem at the moment but it wasn't doing this a month ago so I guess something has gone wrong. I have an old Vulcan Gas boiler. The water pump...

    Understanding my heating system

    OK I have a boiler & a tank. There are four pipes coming out of my boiler, two are very hot, two are cold (well neutral). My bills are very expensive at the moment and I think its because every time we want the heating on (radiators) the tank is heated up too. My understanding is the central...
