Any way of knowing if that’s a combined sewerage + storm water connection you have? Prob no SVP ( soil vent pipe ) but as you’ve no 1st floor WC then doubtful it will make any difference. Are you the end of line, or do you have houses both sides of you? If the letter, can you see SVP’s on their houses?

Can you show where this pipe terminates down low please?

Do you really expect a new gas boiler to be this noisy?

Sounds like a blocked condensate trap / discharge pipe etc. The "smoke" will be "plume", eg the steam created when excess levels of moisture meet the hottest parts of the heat exchanger. The condensate water is acidic, so is chewing through the steel case of the boiler as we type. Google the manufacturers installation guide and in there it will tell you how the service the condensate trap. DO NOT run the boiler with the trap off, as that being removed opens a clear path to the burner chamber and there is a possibility that products of combustion may escape. I'm not entertaining the covid jibber-jabber, but you need a plumber in ASAP to repair this, or one or two a little later to replace the rotten out boiler with a new one. Time to stop bathing with a thermos flask and get some degree of reality and a pragmatic solution to resolve this now.

If this is going to attract big bucks, why ask the question? Dig it out and get on with it !! Agree 100%. Also, you’ll need to provide an EPC when selling and if the floor insulation is dire that will still be reflected there and your marketing will suffer. UK public are far more aware of energy ratings and the longer cost subsequence of buying a pig smothered in lipstick, or as we call them “Persimmon Homes”. Do the job properly, as it sounds like you’re looking to get your money back anyways, just not as much out of the UFH job as you’d like. If it increases the kerb appeal, with no rads etc, which also lends itself to a much more flexible furniture plan, then dig it out, do it properly, and move onto the next job. Allow a week to excavate, barrow out, and prep properly for insulation and membranes. You’ll need 2 men on 2 powered barrows to keep up with removing the spoil created by one digger. Allow another week to install insulation, pipes, edge insulation and screed. Screed should be a one day event, so 4 days of prep / UFH. If you need a very good screeder that travels let me know.

Up to or over 3M you need to upsize with UK Bregs, so 50mm is required AFAIK. I've avoided push-fit waste for over two decades, hate the stuff. Certainly not reliably enough to bury anywhere imo. Can you get someone you know here to box up stuff and post it to you?

Yup. Same supplier too. If you have a single phase electricity supply ( the most commonly found type ) and no 3-phase then you cannot install that unit I’m afraid.

It wouldn’t matter if larger rads were fitted to the microbore if they were pumped from a smaller buffer or low loss header for hydraulic separation. Just about anything can be mitigated with a decent installer.

Russell is now re-homing woodpeckers. I can give you his postcode and he says don’t bother knocking the door, just release them at the gate and that’ll be fine. More the merrier he says. Bloody loves woodpeckers that guy.?

Replace the boiler. Combi out > combi in should be change of £2k with new TRV’s + stat, magnetic filter and a gas pipe upgrade etc ( post-code allowing ). I’ve not yet seen MI’s ( in over 20 years of heating that allow a 15mm pipe to a combi as they’re so gas hungry in DHW mode. They used to say it’s ok to do a gas rate check at the appliance, ergo a short-ish run of 15mm before the appliance would be permissible. They binned that and now ask for 22mm to the appliance as other gas-burning appliances that share the same gas run may not be taken into consideration with the earlier prescribed methods. These days it is 22mm ( or larger depending on the length of the run vs boiler kW rating ), so you are guaranteed the gas delivery that is sufficient for the stated max hot water rates. The radiators you linked to are going to heat linear with demand so you won’t he able to completely strategise your off-peak heating during winter. Bad idea IMO. The instant water heater will be pathetic on a good day, and completely useless when any other tap is open anywhere. Seriously bad choice. Conversely I have recently fitted the 3-phase brother of that ( the 27 ) and it is staggeringly good for an instant. uses 32a per phase!!!! If you had 3-phase I would recommend one of these in a heartbeat. Amazing bit of kit. ?. Fit a new gas boiler, and if you want to show off get a WB unit which can be Hydrogen Ready.

@Russell griffiths has some which is woodpecker-proof. Honest guv!

Were the coils running a brine with glycol ( antifreeze ) inhibitor in it?

It’s mentioned as a dam. Therefore flowing water, not a stagnant lake or pond etc. Flowing water = abstraction license afaik as you’re affecting the downstream ‘condition’ of the water. Further reducing temps in winter can have adverse affects on nature / pond life etc so best to check ( at least ) before going down this route.

Hi. Have you the necessary permissions for abstraction?

Yup. Should have been block on flat for the majority of that wall so it can retain. No sign of buttresses either, which cannot really be introduced retrospectively and effectively.

Basically what MBC are doing right now on a project I’m on. Just so much easier for a client who’s not familiar with building techniques and won’t know things have been missed until it’s too late. A turnkey build with written guarantees of 0.6 ACH or lower at handover is quite an attractive offering. ?.

Eh? Look at the image again. The light has a projecting 4-5mm of metal tube which you skim to. The light fitting is the painted edge, just like a circular stop bead. The finish is done by the plasterer and is flawless, crisp and robust in zero time. Just a wipe clean of internal face of the ‘tube’ with a damp cloth after the skim has started to dry, roller with paint, and you’re done.

Yup. The cheap box was to get the uber-cheap price iirc. I paid £150+VAT for my first one, and £249+VAT for the next ( from Screwfix ).

Eh? Does that mean a rebate if they're not?!

It's quiet when new, but does get noisier with life / dirt / dust ingress. Doesn't bother me tbh, as I'm too busy working to sit there listening to it.

Oil impulse?

You'll see holes in the charger bed which marry up with the holes on the battery?

Fan won't come on unless it's necessary.

This fitting has very soft copper at the point where the brass meets the copper, and really doesn't stand up very well to rotational force. If using that then make sure the screws are in and the fixings are robust
