A heat pump with it's circulating pump under PWM will control flow rate to assist in setting the deltaT. It's under maximum heat demand that things get sticky as pipe restrictions might be fixed but flow though the UFH mixers is not. I'm using an auto bypass to help out in this situation.

I invested in a set of forks for our wee digger and it helped the brickies out a fair bit (one of them was an operator). It wasn't going to get a whole pallet up in one go, but it was a lot easier for sure...

what is an "unacceptable" level of shade?

to keep the refrigerant circuit within efficiency limits

velocity= noise

does everyone with one of these Vortex plants have to do all this dicking around?

we had a pump failure a few months back that wasn't spotted for a week or more, and the system normally only aerates for 20mins in the hour or so; I've never seen any foaming or such in three years.

The power being off for an hour or two is an irrelevance- SBR tanks like our Solido do just this on a regular basis to settle the floc a bit before the clearwater discharge

@Mr Blobby Yep, that's the fibre box. OR are supplying me duct and rope (chargeable) for the 15m or so to the back of the house; our choices for an overhead are limited because of an intervening NIE line and needing to find a sneaky route into the plant room

only if your modem/ ONT is inside in the outside wall, I believe. Google Openreach CSP and ONT for piccies of what goes where.

the lady that came out to value us said their managers would only agree to that if it was still a shell. Habitable? Full rates.

Well that all went better than expected. Regardless of all the "Project Stratum" bull, OR are still expanding their own network themselves. Turns out the next lane over from us has a fibre down it recently, and there's an existing copper line on poles across the back of our site that they're happy to adopt for fibre. Especially when they realised they could get our four properties all on one fibre using the existing infrastructure. Chap went away saying he would make a business case for the network improvement and I'd get something in the post. but... Today this happened 🙂 that's three very happy households!

having had a recent chat on site with one of their surveyors, they generally put a splice point on a external wall connecting the drop wire from the pole to a lighter "internal" fibre that can be passed through your pre-existing trunking to your chosen termination point. Bear in mind that the tech that does the pole joint may not be the same one that does an indoor install. the internal fibre, which is pre-terminated, will slide happily down a 20mm conduit

Will you be able to achieve the necessary airflow when there's a restrictive filter in place?

what's the temperature and chemical ratings of the printed item?

it's a few years back and the invoice isn't to-hand but IIRC it was £2-300?

the silica gel should sort that out in the next few heating/ cooling cycles.

Our TF guys get their pozis from ATS Trusses

I'd caution against taking too much of what is in the Aquafix videos as gospel in the case of our domestic units, as they focus rather a lot on anaerobic systems and the whole point of air-blower plants is in adding oxygen...

worth considering UPVC vs timber too...

that's two independent fans back-to-back isn't it? And both are free to rotate? Might you have disturbed or damaged the temperature sensor?

If you're going through the wall and want to retain airtightness you want a https://www.schiedel.com/uk/products/additional-ranges/ignis-protect/

pretty sure any of the fittings with a male on them have built-in reinforcement

On a whim I filled that form in at the end of the week, and a blokey phoned today and will be calling tomorrow. Watch this space...

^ yep. We used Ignis Protect to go through the walls in an airtight manner.
