hashtag : eating my own words

Just reading back through this top resource as the SA issue has caused a major re-think The solar coil would be too low IMO, particularly at the low temp the buffer will operate at, to be fully extracting the heat out at the rate it would be consumed, assuming max ( typical ) flow of 15-20 l/p/m. I'm getting on the phone this morning to Telford to have a yap with the cylinder gods there and I'l update here with any juicy bits of info I extract. Cant help thinking the arrangement in a standard UVC would be best suited, eg heat via the coil and extract DHW preheat by putting the cold in at the bottom and removing the heated ( 40oC ) water out of the absolute top of the cylinder.

Its OK Capt.F he's been through customs already ;). Just a bit of an overstep with the link so no lives lost.......yet. It goes all the way down my back too so theres a bit to do

Ok, if not tiles then what ? Time for a reality slap, cos pouring hundreds of litres of water, not even clean water, onta a flat concrete floor with no hygienic ( maintainable ) covering is a non-starter. Think again my good man . Impey do a great product for you here, and leaves very little to go wrong. Check this out :). With that you can connect and test the waste before the pour and then just leave that corner shy or get a mix that's workable and trowel it to the former as the lot goes down.

I was having my hair done. .

As it stands, with the PCM34 on ice due to technical problems, not that much TBH. See the last comment in my post here...... ....where ive had to revert back to a buffer tank instead of a pair of 6kW PCM34 Sunamp units. As it says, im just juggling the anti-freeze isolation issue ( minimising the volume of antifreeze rich water by not having the buffer full of that water ) a bit more before I cement a design to overcome this problem.

Nope, nothing.

That one is specific to a customer so just use that to get your head around it

Didn't someone email you a diagram a while ago?

yup

A pile of WHAT?

Just flicking through this again, and agree on the coil if wanting to reduce the A/F volume, but it would still be better, IMO, to have DHW via a ( second ) internal coil rather than a PHE. Accepting that @dogman has already got his buffer, this can now simply be for reference for other readers. The next issue would be down to the size of there vessel and just how much coil can be physically fitted inside it, so at that point you'd probably be into a 300L buffer. Not a problem afaic as its low temp storage so lower losses, and id want as much DHW preheat volume as possible ( to get as much of the bathing temp DHW from the HP as possible eg at the lower cost of producing it ). Current one I'm speccing will be getting a 250L buffer heated primarily by an ASHP, which will be providing DHW preheat for a Sunamp PCM58. Just finalising a decision on the best option for isolating the A/F and primary water bodies. 2 more paracetamol and ill crack it

Just work out what you need to know and bump the other thread

ill need some time to think of a reply to that one

Both charge off PV as happily as the other as a kW of input is a kW of input and always will be. The units are sized in kWh capacity so its black and white. From my discussions the newer types, with the immersions nigh-on direct to the PCM, are pretty much a kW in = a kW stored, so for a rough eg a 9kW cell, regardless of type, should take between 3 and 3.5 hours at 3kW PV output to fully recharge. A gas boiler could charge either cell type, with the correct design and execution. @oranjeboom FYI I have two enquiries where the houses will be all electric all Sunamp. Both utilising the PCM58 with immersions so no ASHP / gas / oil / other. Both, however, will have substantial PV arrays to fortify grid ( economy ) electricity. Don't discount this option as its certainly very appealing in a low energy home

Tres bien.

The one to whack the hardcore under your bathroom floor?

How sad

Thats you perfectly safe for the foreseeable.

Try saying Kent really fast

Deffo. Just be very sure to bury it in plenty of fines, and not to dent or distort it. Arrow straight will help but if you do get stuck you can hire a petrol driven hydraulic winch that'll pull it through. Oh, and ~60-70mm duct minimum.

They send a shiver down my spine tbh, and I'm too aware that they would literally twist you in half before stopping........well they wouldn't stop tbh. To see guys poking shovels in there with their hands on the grips makes me wince, but yet not a single story of anyone ever getting mutilated has burnt my ears. . Curiosty says "go look on YouTube" but the other part of me that wants to go to sleep soon says FECK THAT ! One of the worst site injuries I can recall was done by the humble plasterers trowel.

Steak was nice though.

Took my missus out after what seemed like an age of us just not getting to go anywhere. Decided to go for shandy and drove. Found a nice car park with loads of cameras and thought tidy, vans safe here. Get back at 11:30 pm to find the entrances to the car park chained up and a guy saying "oh, they lock this place up after 11 on Fridays". WHERE WAS THE FACKING SIGN THAT SAYS THAT YOU BASTARDS !!!!!!!?!?!?!?!? 45 min wait for a £15 taxi ride home.

There's no way I'm joining in this one. I know my limits
