    1930's Shell. What do i install?

    If you ask 10 different people, you'll get 10 different answers, but the first vaillant is still fine after 14 years according to the guy who bought the house. Dad's Bosch is just as goof though. The new house I've fitted a Green IQ rather than standard. The gas bills are nice and low, but in...

    1930's Shell. What do i install?

    If you have good water pressure, I'm not sure why you wouldn't go with a combi. I'm on my 3rd 1930 house renovation. 1st already had a new gravity tank system, which worked well enough, but the tank took up a lot of room. Second, no heating and put in a Vaillant Combi. Just so easy to fit...

    Vaillant vrc700 models

    I too was a bit surprised that unlike the 430, it's on or off. I've put some cheap Eqiva bluetooth TRVs in the bedroom so I can turn them off during the day and they work brilliantly! Like you, I think the controls on the 430 were better, so not sure why they felt the need to change them.

    Vaillant vrc700 models

    I did get a version 6 and it works well alongside a 834 Green IQ boiler. I had a vr430 at the old house which was nice and easy to use, but this one works well too. It did seem to take a few days to settle down, but I'm very happy with it. Turning the knob to increase the temperature brings...

    Rewire of loft conversion

    Many thanks all. There's a chance I can run cable back to near the distribution box when I do the plumbing extension and leave them ready for when the kitchen is done, but as you point out, a couple of LED bedside lights and a phone charger probably isn't going to cause issues.

    Rewire of loft conversion

    The very old loft conversion has come to the end of the road and while it's being re roofed, we're going for a hip to gable change, moving the stairs, changing layout, etc. At the moment, the existing upstairs ring circuit has been extended up into the loft. I know it's not best practice...

    Can anyone identify this?

    Thanks all, that's both informative and interesting. It's clearly been redundant for a long time, but I guess no one knew what it was so didn't want to remove it. Barry

    Can anyone identify this?

    I've just removed this from our hallway, prior to replastering, but what it is, remains a mystery. Before I took the lid off, I assumed it was an old doorbell, but it seems a bit over complicated. It's surprisingly heavy and the holes in the base seem to be sealed with something soft, as if...

    Vaillant vrc700 models

    Hi all. Quick question - what is the difference (if any) between a VRC700/4 and a VRC700/5? Is the /5 just a later version? Thanks, Barry

    Internal door quality

    Thanks for the reassurance and advice. I'll see if there's anyone local too. Barry

    Internal door quality

    I apologise if this has been asked before. I need to replace 11 doors (some fire doors) with oak veneer and all roads seem to lead back to Jeld Wen, Premdor and XL Joinery. Is there anything to choose between them regarding quality? I don't mind spending an extra couple of quid, as this is...

    Expanding underfloor area

    Hi all. I installed a John Guest single room underfloor kit years ago which heats an extension of about 25 m2. I'm very happy with it and it works beautifully! We are now planning a loft extension of around 16 m2 and underfloor seems to be the most logical way to go to heat this. My...

    Vaillant Green IQ

    Many thanks, I guess it does make sense not to over complicate it and I'm guessing that as they've been out a couple of years any teething troubles have been sorted.

    Vaillant Green IQ

    We've been using a Vaillant 831 combi for the last 11 years and I've been very happy with it. Other than a diverter valve and a bit of grit jamming the flow sensor after a water main repair, it's proved nice and reliable. The new house needs a new boiler, so the obvious choice is the Vaillant...

    Vaillent 831 running cool

    Thanks all, it's now fixed! Armed with my nice new glasses, I realised the square rod was in the potentiometer 90 degrees out, so max was in fact only 3/4 of max. Just didn't come to light until it was cold enough to need more than 3/4 heat.

    Vaillent 831 running cool

    I went through it all , but nothing obvious. I also did a reset to factory defaults, but no difference

    Vaillent 831 running cool

    It makes no difference I'm afraid. It's set to maximum all the time with the weather compensator fitted, which I think effectively by passes it. As I said, it will fire at full bore for hot water, so it's something on the central heating side I'm sure.

    Vaillent 831 running cool

    Yes - last year, by a Vaillent engineer. Had the graphite seal replaced at the same time.

    Vaillent 831 running cool

    Hi there. I have an 8 year old Vaillent 831 with VRC430 weather compensator, which has been running well up until this cold snap. It's been completely reliable until this summer when the main board went and was replaced. With the sudden drop of temperature this week, it became obvious...
