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

Yup. If you use a battery to the point it gets quite hot, when you put it in the charger a thermistor says hold off on the charge but start the fans to aid cooling it ASAP. When cool it will then start to charge. That takes a 30 min charge to 45 mins to an hour or more as it cools first then charges.

Yup. He could at least put a bit of makeup on while he's at it too.......

Tough crowd this evening......

?

If it's for women, shouldn't it be Norkstrand?

Strange. I've pounded my Makita brushed and brushless stuff into the ground. Couldn't expect any more and very happy with how they hold up to a beating. I've smoked a few drills in my time but I've known that what I was doing was abuse so cannot possibly complain. They died a viking death at the hands of a man who wanted to get done and get home

OK. Because a Welsh fella is TELLING YOU NOT TO BE!!. Flush the shit-heap of a system that you have there currently completely from your brain. Do some Yoga or whatever to rinse this completely from your soul. It is no longer a subject for discussion. There is no future in this past, Chinese confucius says......"Our greatest glory is not in never falling, but in rising every time we fall." Breathe in through the nose....and out through the mouth. There.......Better? The box of shart that makes all the pump and COMPRRESSOR noise is being replaced by a heating pump which is nigh-on silent, and the compressor will now live OUTSIDE. Forget the gears, and frost noo-nah etc, 'twill be a thing of the past shortly. So; If the NEW unit needs to 'defrost' then the external unit ( now full of glycol infused brine ) will request heat ( even the cold water in your rads will be considered heat at that time ) and then the system will come on and reverse the normal operation to aid in a fast defrost cycle. That will ( bloody well SHOULD ) only happen when you are in a heating or DHW cycle and the unit runs to the point of freezing up. Again, SHOULD, but realistically SHOULD NOT be to any degree of significance because of the glycol ergo it should only be the 'radiator' part of the unit that freezes up ( not the whole thing turning to a block of ice ), BUT and MOST IMPORTANTLY you do not use the heating or hot water at night ergo the new unit cannot go into DEFROST cycle. It may go into FROST PROTECTION and start up and run ( which would be then identical to if you have turned CH on to run ) but only at the absolute minimum heat output to stave off the unit then going on to freezing from atmospheric conditions. The problem will go away. If it doesn't I will come there myself and beat the fcuking thing into submission, personally. Using a severed heating installers limb as a club of course. Stop typing here, reply to Vaillant to get the new system fitted, and then reply here ONLY ONCE IT'S IN and WORKING and NOT BEFORE. "Capiche?"
