    Bi-Fold Doors - Traffic Door Dropped

    My bi-folds have been in for about 8 years and the bottom corner of the traffic door has been catching for about a year. It seems like the door has dropped a little so i need to adjust it, problem is i cant seem to find any way to actually adjust the door! The hinges do not appear to have any...

    TRVs - I bought the wrong ones but why?

    Perfectly confident - Its just they look a bit seized up having been in there for many decades. I guess i just need to give it a go.

    TRVs - I bought the wrong ones but why?

    Is there a particular reason a TRV body is not made to fit onto the larger diameter tail? These radiators are old imperial units and i am not convinced i'd be able to get the tail out, they have been in for a while!!! Ideally i'd swap the rads too but they are in decent enough condition and the...

    TRVs - I bought the wrong ones but why?

    thanks for that although i'd rather avoid swapping the tails if thats possible with a different TRV? I dont understand why a drain off valve of 15mm / 1/2 inch is different to the same TRV?

    TRVs - I bought the wrong ones but why?

    I am installing a drain down valve, as i dont have one, in my open vented CH system and at the same time taking each radiator off and giving them a good flush. I recently took one off for decoration and the amount of thick black sludge that i flushed out the bottom was alarming to say the least...

    Central heating drain

    interestingly ..... I was at the F&E tank looking at the vent so that i could bung it while the hot water was on but the CH was off and water was being pumped over the vent constantly. Does anyone know where to look for what could be causing this? I googled around and i hear mention of a...

    Central heating drain

    With regard the installation, it looks a touch agricultural to me for sure but alas this was deemed acceptable to the guy who installed the system. The pump is on the ground floor and so circulating over 3 floors which makes me think perhaps a greater head is needed. The radiators have been...

    Central heating drain

    I did wonder if the vent question would generate some Lolz but thanks for educating me. here are a couple of pics of the valves that also need replacing. As I said sometimes it gets noisy and others it just seems to lack efficient circulation hence me wanting to swap it out and see where I am at.

    Any clues where the vent may live?

    Central heating drain

    Yes, the gate valves are knackered and need replacing along with the pump. To replace the gate valves I need to drain the system yes? Will post a pic later

    Central heating drain

    Ok when I get home I will. The main reason I want to replace the pump is that I don’t think it’s working correctly or consistently moving enough water. sometimes the heating works perfectly and others some of the radiators take an age to get hot. No amount of bleeding or balancing helps and...

    Central heating drain

    Hi - I need to drain my central heating to replace the pump, it’s an open vented system, but as the gate valves are also corroded it’s a full system drain first. I do not have a drain valve that I can find but I do have a downstairs radiator, by a door, that has this - if I undid this bolt and...

    Central heating 'Reversed Flow'

    Not difficult for me to understand, just that when all the information i get from 'guides' mentions that the lockshield is the return then i guess i understood there was a reason for that. I of course understand that a radiator just works by water flowing through it, and so direction should not...

    Central heating 'Reversed Flow'

    So tonight i turned off one of the rads that gets hottest and yes one of the less hot ones got hotter - So i guess i have to turn the lockshields down on the hot rads even though they are the inlet side. I will try it and see how i get on although i bet some of them will start weeping as they...

    Central heating 'Reversed Flow'

    It's a Greenstar 30 CDI Classic Regulator according to the sticker just inside the door. Alas this was all done as part of a kitchen extension job so I can't contact the guy who installed it and to top it off the builder went bust too so can't get in touch with them either.

    Central heating 'Reversed Flow'

    Hi - i dont believe the boiler has a pump in it as if it does then we have two! These are some pics of the pump and the valves - the valve on the right is for the rads and the one on the left is for the HW - I have no clue how i would work out which side of the boiler from a flow point of view...

    Central heating 'Reversed Flow'

    It's not that I expect them to be I the right or left its just that the lock shield valves are on the left on all my rads and this is the side that has a higher pipe temp hence me assuming the flow had been reversed during the install. Is there anything else that could cause this and if not...

    Central heating 'Reversed Flow'

    We only have 2 trv's in the whole system but the fact is the lock shield valves are way hotter than the inlet valves on all the rads. The boiler was swapped but lots of other changes were made. The hot water tank was also swapped out along with the addition of the motorised valves as this...
