    Need some second opinions on new hep installation work

    OK, so now I am a little more worried and one more judgement call for you all if I may. One of the radiators upstairs has been put in with the pipes chased into the wall and the tails caming out of the wall. There is therefore one or more hep joins in there. It transpires that he has...

    No, it's a valve on the water main. No gas there :)

    Do you all still use that thin hairfelt stuff insulation - seems pretty below par for current regs these days, but much easier to handle? Otherwise spacing out the pipes enough to fit on chunky pipe insulation is difficult...? Guess you just have to do the best you can? I've seen lots of old...

    Need some second opinions on new hep installation work

    Thanks lawrance (and everyone else). If that is the case then I shall ask for the work to be redone. It seems sensible to change to copper at the same time given all the comments. Roughly how much extra time and material cost should I allow him to move to copper (not for the reworking - he can...

    Need some second opinions on new hep installation work

    Mmmm...sounds like copper is coming back as the common theme here. I am willing to renegotiate on costs if I am at fault - I am not trying to be cheap; cost is an issue but it has to be done right at the end of the day. I think my instincts were correct. lawrance - can you be more specific...

    Need some second opinions on new hep installation work

    I'm having a some existing pipework redone in the subfloor and a new radiator put in (plus feeds for shower and water softener and a further one to relocate the stopcock, hence all the runs back and forth) - see pics. The plan is for floor and walls will be fully tiled. The work has...

    Vaillant EcoTec937 hot water cool after 10min...design flaw?

    We have a fix! The problem is our age old friend limescale had clogged up the heat exchanger plates that transfer heat from the boiler to the charging tanks. Engineer fitted a new set of plates and all seems to work fine now. I am still a little puzzled how on earth it managed to recharge the...

    Vaillant EcoTec937 hot water cool after 10min...design flaw?

    Well, it's definitely a fault, and an unusual one by the sound of it (heat not being transfered from the heating plate to the charging tank). Engineer called back to base to discuss and is coming back on Wednesday to replace a number of parts in one go as he didn't carry them as standard on the...

    Vaillant EcoTec937 hot water cool after 10min...design flaw?

    Yeah, sounds like luck has not been on our side on this one. Thanks for your help on this one, it's been driving me mad!

    Vaillant EcoTec937 hot water cool after 10min...design flaw?

    that's scary...looks like you where prophetic - boiler just stopped giving hot water and started showing F81/91 codes!

    SG11, presumably a few cover this area?

    Vaillant EcoTec937 hot water cool after 10min...design flaw?

    It's relatively new, only last few months really. Very true. But it does depend on how much of that heat is actually being transfered to the water that comes out of the hw out pipe I guess (I presume that the boiler pipe is not directly connected to the hw outlet to the property)? Result...
