@JohnMo did I mention hot tub or has something gone haywire with the forum? Anyway I'm all for hot tub and aircon and whatever else people want to use energy for. Knock yourself out as far as I'm concerned would love to be sitting in a hot tub right now.

I just don't agree with charging high users more per unit. The price is the price. Why punish people for using more? Let's just focus on energy abundance. Improve the generation capacity. Same story with water really, increase supply or storage. Countries with reasonable energy prices can afford to desalinate.

Why? That is terrible. Is it so the pipe is joined outside the building? I've had pipes join under a building before probably isn't best practice but when you see something like this it hurts your eyes. In my case the stub stack coming up might have been accessible to rod a blockage thru so maybe thats why was ok. If you do want it going into that manhole it can be done but just take a long swing into the 90 deg connection of the manhole. You want to be forming a slow bend in connections so the waste is already flowing around.

Without wanting to get in to a slagging match why would you want to punish high energy users? Surely the attitude should be I want us as a country to produce as much energy, reliably and as cheaply as possible (plus cleanly if that bothers you). It just seems such a backwards way of thinking to me and feels like it's why we're in the position we are.

Hasn't there been issues here before mixing business interests with forum advice? I know thats not where you're coming from with it but I seem to remember some aggro previously.

Beware the tool less change does start to play up after a few years i scratch around with a screw in the hole then tap and blow the dust out seems to sort it. I'm running 2 atm. One for rubbish dusty work and a new one for cutting timber.

They have sensible energy prices unlike here. Even in Australia its not unheard of for them to have aircon in their garage or tool shed. Another quirk i find they seem to be able to build a lot more custom things. It appears to me they can stick build with timber over there and as long as they follow local codes they're good to go. I feel like over here we need to involve a structural engineer for every thing unless its an approved detail.

Thought they were a bodgers tool before I bought one. Great bits of kit.

Would it be possible to cool the accumulator in any way?

I don't think there are any regs for insulating cold water pipes in domestic dwelling. I've certainly seen plenty of un insulated pipes in my time. Are you looking to claim from the plumber? I don't think they problem is avoidable if you have a tank in the house at room temperature regardless what you do with the pipes.

I don't know why you think I'm personally attacking you. I'm just giving valid criticism of what often happens on the forum lately. Someone will start a topic saying let's discuss A or B then C gets bought up. Again I can understand why in some cases but this topic didn't really warrant it. Also I think its disingenuous to say 75mm of insulation over a poor b&b floor is crap. These systems have 150mm between the beams then either 75 or 150 over the top. They can hit or better the 2022 u values of .13 for floors. I dont think .13 is crap by any stretch of the imagination. With this project im not going to start agonising for weeks trying to improve u levels by a certain percentage. It sends you mad. I'd much rather accept a certain running cost to the house and focus my efforts elsewhere. Again sorry if I offended you the forum has changed a lot since the earlier days. I also believe ai does have a place for answering quick queries. There is no guarantee but the same can be said with anonymous strangers on forums.

A good benefit is reduced dig out compared to normal b&b with closer matching ground levels. Think you can get the difference between ground level outside and under slab to around 300mm

75 on top would be 225 in total with the 150 between beams. I think you can up the spec of the top sheet to achieve .08 u value according to the websites. But again we are proving my point here. The thread wasn't set up to debate whether beam and block is good or not. Just what appears to me the glaring cold bridge in one of the options above compared to the standard way these 'warm' b&b floors usually work.

Its not that bold. A normal ground bearing floor is susceptible to heave, suspended one less so. I have trees very close to proposed house. Better to plan for the worst. I started the thread as I was interested in the difference between the cold bridges on the 2 different systems. I wasn't really looking for a discussion on whether to use ground bearing or suspended floor. This always happens on this forum. I can see why it has quietened down with ai.

Also certain trees mean deeper foundations which mean suspended floor is the better option incase of heave.
