Gone West

When I was designing my last house I used the PHPP, and I ran some iterations to determine the sensitivity of infiltration on the space heating requirements. There are the results for my particular design. This was back in 2009 using the 2007 version. Pressurisation Test Result (ACH) Specific Space Heating Demand (kWh/m2) 0.2 12.1 0.4 12.3 0.6 12.5 0.8 12.7 1.0 12.9 2.0 14.0

Back in the 70s when I bought my first house, I also bought a book called The Conveyancing Fraud. I thought I could save some money. After having read it, I chickened out and used a solicitor. It was an interesting read though.

This question came up last week, although I don't think the appliance was named.

I used ipe, pronounced eepay, for my balcony decking at the last place. No treatment required, very hard wearing and resistant to insects and rot. Also expensive though.

Welcome to the forum. Nice looking property. Are you happy to have your names and address on the drawings or would you like to cover them.

The local fine sand in this area is pale grey which when added to Snowcrete produces mortar of a similar colour to your picture.

Welcome to BuildHub. It sounds like you've got some useful experience, but if you get stuck, there's plenty of people who will help on here.

You could use Cedral Click cladding instead of timber cladding. I have recently used it and if you want a painted timber effect it's very good.

We moved into our new timber frame, timber clad, self build in 2018. We had no problems insuring it, neither did the new owners in 2021 have any problems obtaining a mortgage or insurance when we sold it. Regulations may have changed in the meantime though.

You would be right to, if you hadn't designed the house to have only a very low heat requirement. MVHR does only move relatively small volumes of air, but if that is all the house needs, no problem. There are people living in places as diverse as Inverness and Penzance so there are significant variations in heating requirements due to climate, not often mentioned. There is not a single solution for all designs. Fortunately, UFH is not the only way to heat a property, so it is comfortable. Before I built my low energy house, I too visited PHs that weren't comfortable, and they had UFH. It is not too onerous to meet the threshold criteria for a PH, but they can be bettered, reducing further the space heating requirement.

As I mentioned, the Genvex Combi 185 is a MVHR with a built in EASHP. The HP heats the 185l hot water tank and provides warm air through the MVHR. I bought my Genvex direct from Denmark many years ago at a fraction of the cost from THE.

I designed and built a PH that didn't need conventional central heating. It was heated using an electric towel rail in each of the three bathrooms and by warm air heating from a Genvex Combi 185. The temperature of the whole house was kept at 23C. It only worked because the house was only 130m2, had good air tightness and very good levels of insulation. It was a very pleasant environment to live in.

I'm using a Predator saw/knife to cut mineral wool insulation and it's suprisingly effective. It's a tough material, a lot different to EPS/PIR. Worth a try for a tenner from Amazon.

This could be true! https://www.independent.co.uk/news/uk/politics/ed-miliband-warm-homes-solar-power-energy-bills-b2892047.html

Yeah, that was ten years ago. Before we moved, I had a blog on here.
