hahahahha this is absolutely resolutely not about saving! The opposite!

Hello all, I've just completed a long-term project of mine to use a waste water heat recovery system (WWHRS) to boost the flow rate of an electric shower. And it's worked an absolute treat. In initial testing, I'm getting a shower flow rate of 15 lpm, which is around triple what a 10.8 kW normal electric shower would give. Here's my final plumbing: I used a Stiebel Eltron 10 dce-s 10/12 plus water heater, which is capable of 12-14 kW power (changeable by jumper). The WWHRS is a Recoup pipe hex rd active. The waste water from the shower is pumped to the top of the WWHRS, where it transfers some of it's heat energy to the incoming cold water, prior to it going to the water heater. In my initial tests, I'm getting a heat recovery efficiency of around 55%. Total energy in the water flow 31.4 kW, 14 kW coming from the water heater and 17.4 kW coming from the WWHRS. This is better than I expected. I've made a big long rambling article about it on my website https://www.microhouse.scot/plumbing/high-flow-rate-electric-shower And will be posting some videos about it on my social medias this weekend. Let me know if anyone has any questions about it!

Thanks :) My website is www.microhouse.scot - all my architect and structural engineering diagrams are on here if anyone wants to take a look. Instagram/tiktok are @micro.house.scotland Yeah Nordlux Aludra. The colour is Aluminium, but the place I bought them from doesn't sell that colour any more, I just checked. And can't find elsewhere, so maybe been discontinued. Weird, only bought them a few weeks ago! Thanks :)))) Not really my choice as such, I just did as commanded by my structural engineer. I think in general the building is very over engineered, which I like :)

Thanks a lot :)))) Yeah, it's built round it. Underneath the branch itself I made a section of the roof just with lead sheet. The tree doesn't move at that section, it's a very bi diameter crotch. ATM i'm using the underneath for timber storage. I'm in two minds about what to do about it TBH. In future there will be decking which will close off the front. There's membrane under there, nothing living so far, I think it's too exposed just now. Someone said to me at some point, that if i close it off, it makes it more attractive to rodents, and they will find their way in. Unsure, will decide on that another day!

Thank you :)))) They're from Spirafix. They're hammered in as opposed to screwed. Then there's a big steel beam figure-of-eight structure on top tying them all together.

Hahhah only briefly, the pigeons love to eat them! TBH the tree didn't make many this year, think he was a bit thirsty. Pear tree next to him also didn't fruit. Yeah I did the char myself, double burnt it with a roofing torch. Was a much bigger job than I expected. Burnt through about £300 worth of gas!!! oooh DIY air tests?? Will have to search that up

Yeah more people should! It's slow going when you're learning every stage as you go, but it's been fun :) It's approx 7.7 x 3.8 m externally

Hello all! Just found this forum yesterday, and already found a lot of useful discussions! For the last 3 years I've been building a wee annexe/enormously overbuilt shed in my garden that I call the 'micro house'. I'm a DIYer and this is my first build. I've built 100% of it myself with no professional help so far, aside from architect and structural engineer for the pre-build warrant paperwork. Some features about it: Full regulation / Scottish Building Standards / warrant build Built on ground anchors / screw piles to protect a ~300 year old copper beech I built right next to Reclaimed Scotch slate roof on traditional sarking boards Lead ridge Burnt timber cladding Zinc gutter Highly insulated and air tight, close to passivhaus, but this is as yet unconfirmed (hoping I can find advice on that here) dMVHR Wet room bathroom (about to build this out) It's taking me a billion years for a few reasons, but I've been posting my incredibly slow progress on instagram and tiktok if anyone is interested to take a look. Aside from building, I work abroad as a scientist and engineer for a chemical company that supplies the oil industry. Nice to meet you all! Look forward to contributing to some of the discussions where I can. Let me know if anyone has any questions about my build, lots of pics attached. :)
