Gone West

I used Rockwool RWA6 which are batts or slabs, as EWI on my build. I assume RWA45 are also batts which are resin bonded, fairly rigid and easy to cut and work with.

We put our old oil tank on Freegle and it went within a week. It only had about 50 litres of oil in it but three blokes, a trolley and a trailer and it was gone.

We bought Internorm PH entrance doors and fitted them ourselves, although that was eight years ago and things might have changed now.

This is the data sheet for them. Perlight Delta Data.pdf

You could use microinverters so it's AC going into the house. If I do fit PVs I will use microinverters so I'm not putting heat into the house in the middle of summer from an internal inverter.

We have an Isoquick PH insulated raft foundation. We have a single stud wall, but the 'stud' is a timber I-beam. The I-beam sole plate sits on the edge of the concrete and all the Icynene insulation is within the I-beams. There is 15mm OSB3 racking on the outside of the I-beams with external rockwool insulation on the racking board which joins with the EPS upstand.

The insulated slab is Isoquick and they were the company who installed ours, which was the first in UK back in 2010.

I did look at Perlight as well as LG and Panasonic when I was thinking about installing PV. I'm still wondering if it would be worth it. https://midsummerwholesale.co.uk/buy/perlight-monocrystalline-solar-panels/perlight-delta-285.html

We fitted an recirculating extractor unit to ensure that any cooking oil vapour in the air is trapped before it can enter the MVHR system and condense in the ducting.

You could try WiMax if there is a supplier in your area. Then you could still have a local phone number via VoIP in the future if you wanted.

No reason at all, ours is downstairs in the utility room and easy to access.

Yes that's what it's says on their website. http://www.brettmartin.com/en-gb/plumbing-and-drainage/products/plumbing/push-fit-soil.aspx

If you used grey EPS slabs you would need about 280mm to equate to 200mm PIR. Don't know if you can hire equipment for blowing grey EPS beads.

In practical terms not a lot really. You'll need downstairs heating at least even with triple glazing and good airtightness. In my experience from running PHPP with different U factors etc if you're in the south of England you'll need a U factor of very close to 0.1 W/m2K to not need a conventional heating system.

Hi, welcome to the forum. Don't worry we've all been there and generally there's always an answer.

I've done a bit more digging and found this table which indicates there is a PV version, so is the UniQ dPV the version you have? http://www.bublshop.co.uk/files/pdf/pdf1958b.pdf

I've just looked at the Sunamp website and can't find any reference to the SunampPV. The only product they seem to be selling is the UniQ. So I presume all the old Stack, PV etc products have been discontinued.

We visited Richard Hawkes PH around 2008 while it was being built and he had paraffin wax phase change panels in his walls.

That's correct, the reason they gave was the warranty runs from when the house was weather tight. This was because the build was taking a long time to complete. I couldn't be bothered to argue, at that stage I had more important things to worry about.

They removed our bungalow from the Valuation List once we had the electricity connection removed by the DNO. We used the disconnection documentation as evidence.

Superb, well done.

Our UVC is part of the Genvex Combi and is 185l. The water is heated by an EASHP which is built into the Genvex Combi along with the ventilation unit. There are only two of us in the house and we use water saving measures as much as we can. We have never yet run out of hot water. It doesn't sound as though 185 litres would be enough for your usage.

Hi Murray, welcome to the forum. We have also built to PH standards using a novel wall construction. We use three electric towel rails to heat the house which is supplemented with warm air heating from a Genvex Combi 185. Is it possible to bench test the post heater?

There was a substantial saving by having it crushed on site rather than having it all removed and new recycled type1 brought in. It would have taken several days to load it by hand and a broken back!
