Yes, I had thought of PIR insulation especially as a neighbour has thrown several large off-cuts in his skip. I hadn't thought to seal any gaps with polyurethane foam so thanks for that idea. I have got 30 odd 15mm and 22mm x 2 metre lengths of unused black nitrile foam pipe lagging (Armaflex...

Hi Alec, I don't think I have explained properly or I don't understand what you are saying. The issue is not where the pipes pass through the notches in the joist, it's where the pipes span between the joists as the floorboards almost sit directly on top of the pipes with perhaps a 2 to 3mm gap...

So toastier radiators and underfloor heating.:giggle: It seems anything that provides an escape path for the heat is frowned upon these days, no gaps, thinning, air movement from within etc. Won't pulling the cable ties tight deform the insulation pulling it away from the floorboards producing...

I have posted before about our heating but have not really found a solution, so apologies for any duplication. I'm after some advice on how to insulate the central heating pipes beneath our ventilated suspended timber floor, where the pipes cross the floor joists. There is insufficient...

The existing boiler is a Glowworm 30CXi that has a leak in the primary heat exchanger, that is draining thru the condensate pipe, which is the main reason for the change. Polesapart - is mounting the boiler on a flammable surface e.g. ply, permitted under current regs? Being a retired sparks...

Cross thread, thank you for your reply. Would you expand on what you've suggested.

We're looking to have our boiler changed later this year. The existing boiler is mounted on a 1960's block wall that is part of the kitchen. This wall gets very warm when the boiler is in use and heats up the wall cupboards on the kitchen side such that we can't use the cupboards for anything...

Changing the hex is probably well within my practicable capability but that would be illegal and not for me. Putting in some sticky jollop to extend its life while we save for a new boiler is one thing but changing it - nah. We'll have the boiler changed for a nice new efficient one by a Gas...

Just before Christmas my partners central heating system in her early 60's bungalow started losing pressure. During the day the pressure was fine but overnight it would drop below the minimum and need recharging in the morning. To cut a long story short I couldn't find a significant leak...

The only problem was that the downstairs stat controlled the upstairs circuit and visa-versa. That has now been changed as part of other work , see thread https://www.diynot.com/diy/threads/wrong-zone-valve-actuator-head.618949/ Thanks for the help

That would have been a good idea had I not already replaced the existing wiring centre with a slimmer one. I had to cut the architrave on the inside of the frame away to fit the new box. Your idea would have been better solution using the box suggested above but jobs is done now and all seems...

Job done. Thanks for the help

Sorry, I don't see the relevance of the Regin socket to drain(ing). I don't intend to alter the wiring to keep the existing actuator, I will replace it. I'm just concerned that someone else has tried. The original installer of the wrong head may have done something to the connections to try and...

First picture is of cable extension to HW zone valve from wiring center. Note white wire from valve (bottom connector) becomes pink wire to wiring center (top connector). Second picture is wiring center which, as a sparks, I shake my head at. Getting a better picture of the wire layout will...
