Should I pick the narrowest width stuff so it doesn’t interfere with my fixing brackets/straps? I’m using uPVC from deceuninck (sp)

That's the sort of thing my wife needs

Interesting, would this be the way to go, in your opinion? Windows going into new blockwork with bang on widths (brickies have done an excellent job).

paging @craig, could I forgo the fm330 and the standard compriband and just use TP654? I guess I would still need to seal back with me508 from the face, over the closer, and back to the inner skin of blockwork?

Automotive panel wipe, the solvent based one. Designed specifically to remove silicones prior to painting.

Yeah, I've got all that already... I was just looking at the window specific/airtightness stuff. I usually just screw the frames in with frame fixings and foam them.

This is why a2a is the way forwards - turn it on, heat pours out, turn it off, nothing comes out...

Fitting some standard uPVC in a couple of weeks, would the following shopping list be ok: Straps/brackets to fit the profile 5-10mm compriband to go round the outside edge FM330 foam (1 box of, gun grade) to go behind the compriband, shot through with a long nozzle from the back Airtightness tape for the inside, window to cav closer, closer inner edge to blockwork - assuming Illbruck ME316 (as that's what doortech direct sell) Not going all out nuts on this extension, but want to do this correctly...

Back in stock at appliances direct, woohoo

Back in stock at appliances direct, in case anyone wants one...

Interesting looking forum, might join...

Yep, post spec and pictures here in the for-sale section. Although I note there's alread a daikin package for sale in bristol on FB so you're competing against that...

ebay/facebook... Don't go asking stupid money mind you. I buy and sell a lot of used stuff (appliances, machinery etc) and I would expect to pay about a grand for a package with a monobloc unit, a UVC, expansion, a wall controller.

Judging by the controller picture, these are OEMd by Midea... For flats, I would go for an a2a VRF multi head unit from a commercial supplier (Daikin), and a sunamp or direct UVC for the hot water.

Best thing to do with a chimney is take it down...

I've done loads of illegal electrics over the years

To add to the original list, under the Reversing (may/may not be installed in pairs/interconnected): BSK Zephyr - https://www.bpcventilation.com/bsk-zephyr-single-room-heat-recovery-unit#accordion This looks really nice, and appears to be a premium product at a not-so premium price.

The more I look at the Greenwood CV2 range, the more I think we need one in our bathroom (we don't have anything at the moment and are about to do a bathroom renovation). Is it possible to vent these through the roof, into the loft, then out through the sofit/fascia? Or is through-the-wall preferred? I would look at the 24v option because bathroom....

An interesting discussion about the Lunos... Not sure how relevant it is, but it's an interesting video nonetheless.

Yep, unless you're brown/blue colourblind just do it yourself and pay BC for a sign-off...

I thought that this list would be of benefit to the group, it's a summary of my most recent research on the dMVHR issue...

But I hope that list is helpful.

Blimey...

I've got a 16mm bender, I always try and bend as much as possible.

Fair enough… I’m a close my eyes and visualise it sort of person so I have no need for drawings and all that guff 🤣 my builder is a building notice kind of guy so we get on well.

The issue with 16mm is the internal bore of some of the fittings. I use 16mm mlcp wherever I can, but I always try and minimise the fittings count, as they are restrictive.
