Where does that come from as it is pretty useful for estimating.

If you watched 4 GD's back to back, I would say that is a sign of stress. Get some help.

I liked living down that way, though my house was in what, was 30 years ago, scummy Weymouth. Interesting that the nexgen website is not active. Maybe we have had some real influence on a company.

Not sure how things have developed in 35 years, but we used to incorporate this sort of heating element into moulds for insitu post curing. They were very 'patchy ' to say the least. Some areas got very hot, other areas had no heating at all. Also I don't think you can reliably run directly from PV. You will need some voltage regulation. A normal domestic solar module runs at about 72V. So outside the scope of ELF I think. And that is before power point tracking is considered. If you can fit normal wet UFH, the water can be heated with just about any energy source i.e. Heat pump, wood burner, bottled gas, oil fired, electricity, small boy scouts rubbing their knees together etc.

I used to manufacture both log and panel saunas. These are basically small houses. Panel saunas, when outside had worse thermal performance i.e. they cost more to run. Log saunas had, as @JSHarrissaid, large coach bolts though the timber that had be periodically tightened. I preferred making and installing log saunas as they were more profitable and the finished product was, in my opinion, much better.

Welcome Don't confuse low voltage with low energy. Voltage is only part of Ohms Law. There are, and I am sure an electrical person will come along and say more about it, different rules for High and Low voltage. Low voltage is anything under 1000V, but then there is Extra Low Voltage. If you have not read this, may be worth it NextGen. Sounds like an interesting project you are involved in, where about on South Coast are you?

Have you updated and upgrades recently? sudo apt-get update && upgrade

Give the fans a go, it is a cheap way to eliminate one thing.

Never criticise a your wife's choices, look who she married. Though I often find find they are like kitchens, better than what I have at home.

He looked a bit young for that. Think he was a producer. There are some jobs that are not that costly when you make a mistake, and/or cost other people money. Other jobs drag you down with it. Kevin did joke that he may not live long enough to see it finished. He should have done it in stages. The tower could have been put up later, it was only a steel structure after all.

I think @JSHarris had one of those combined cylinders with the F&E tank on top. Mine is just a bog standard cylinder. The F&E is in the loft. Have insulated the pipes.

Renovate it properly and any dampness should be a thing of the past.

I would forget PV, seems you are surrounded by trees. As for ASHP, that is just a sizing issue. Work out your current heat load, that will give you an idea what will be needed in future. I don't understand why you want a limecrete floor. Better to dig out what you have, lay some proper insulation, then a concrete floor with under floor heating. At least you will know that the floor will set hard. Regarding an wood burner, why, they are inefficient, very polluting and hard work.

Landscaping a lake at the moment I would have thought.

Time for a party then, not trashed a newbuild yet, done loads of student HMO in the past though. No one knew I had been there.

There may be a different methodology used. So treat the numbers with caution. Having said that, because of the losses from my cylinder being higher than my usage some days, I added extra insulation. Not a hard job to do, if you make sure the box for the cylinder is in a sensible size i.e. not small.

It is really a by-product of changing to CO2. From what I have read, the CO2 is kept in a super critical state, so basically relies on the energy levels of phase change. This allows more energy transfer by volume. CO2 does not like being a liquid. The move to CO2 is to reduce the global warming potential of gas leaks, not improving the efficiency of the unit per se.

I think we should start up a TF house factory. There is enough community knowledge and way too much free time. There is a company called Frame down here, not sure if they do one offs now though. www.framehomes.co.uk/

Just noticed this on the BBC website. Not sure it is a true reflection of life down here. https://www.bbc.co.uk/news/uk-england-cornwall-49837050

You could make your own dasey cutter. https://en.m.wikipedia.org/wiki/BLU-82

There was a push over a decade ago to give out free energy monitors. Trouble is, most people that got them had no idea what it was showing them.

So if a house was 80m2, that is £150000. Probably pretty cheap for Norwich.

What I have been doing for years.

Anyone know what sizes these places are. They look similar in size to my place, which is tiny.

Came from some insignificant Scottish Island. Orkney. SunAmp had a mention. https://www.bbc.co.uk/programmes/m0009372
