    Issue with one radiator in open vent heating system no flow

    OK don't have one of those:-( I am using a twin barrel footpump. I am guessing I have a blockage that is reducing the diameter of the 15mm pipe but not totally. Then when I pump it up the pressure gets greater beyond the blockage then when I release the pressure the water gushes out due to...

    Issue with one radiator in open vent heating system no flow

    OK so have an update. Rigged up a washing machine hose on the return of the offending return valve union this was not flowing other than minor dribble. Gave it a couple of pumps and then got good flow. Put everything back together and still not working. So moved onto the flow pipe which after...

    Issue with one radiator in open vent heating system no flow

    @Madrab the 15mm pipework goes under the floor of the bedroom not sure where it goes from there onwards. There are 3 beds upstairs and one bathroom all with radiators in. The 15mm from the F&E I believe goes to 22mm as there is a box section near the newel post that has 4 22mm pipes in it...

    Megaflo indirect unvented leak woes

    Thats what I was looking for :-) At the moment performance seems ok with no output from the tundish. In respect with a bit of tenacity I would say I can get the majority if not all the limescale out. The bit of plastic hanging around I am sure I can get that out. Does this mean my internal...

    Megaflo indirect unvented leak woes

    Hi, It is leaking from the immersion. On investigation it is not the flange but the actual rod of the element where it passed through the immersion heater into the water jacket :( Got a new one and went to fit it at the weekend but was alarmed by the amount of limescale in the bottom. It wasn't...

    Icicle hanging from flue on condensing boiler

    All, just been round a rented property and noticed that the flue has an Icicle hanging from it. It is quite a long flue run ie. not just straight out the wall, comes out about 40cm or so due to roof overhang. Is it something to be concerned about? I thought flue was supposed to slope towards the...

    Vaillant ecotec plus 4xx versus Eco Fit pure

    What is the difference apart from external dimensions? I see the turndown ratio is not as good on the pure so does that mean different HeX? Does the pure require as much flow like for like output? Anyone fitted a pure what is the startup logic like. Thanks
