It is.

Think that is called a barge. Bit like when Kevin McClod put his caravan in a whole, but more watertight. There was a bit in the climate press the other day about flood risk. The 1:100 events are now 1:20 while the 1:1000 are coming in at 1:100. That is globally I think, but the UK is not well places geographically. But having said that, after a month of daily rain, I have not seen any bad floods. A few years back we had some bad ones. What I have seen is a lot more ditch cleaning by farmers. So maybe lack of maintenance caused some of the problems down here. Who knows.

Can it sense the strength of the field around the wire to a useful accuracy?

Could you not set up a simple device that just monitors power via a CT clamp. Be easy enough to work out which part is drawing what current if you really wanted to. Or just use a relay to close a GPIO pin. An RPi can send an email, or even a text (as long as it has a few minutes battery backup, along with the router)

During that episode, they often cut to video of the wife looking miserable. That may have been post editing license. I also suspect that the things she initially liked about her alpha male husband, vanished when it all went wrong. And who knows, she may have met someone else and the sparks just flew. Or he may have.

A bit more digging and the Bude Canal will be complete.

Typical Devon, half their shit ends up in Cornwall.

And almost certainly got his fees.

Yes, just a standard GRP system. Nothing new about a powdered hardener, been around for decades.

Heat does not 'rise' in a solid, so I am not sure how much difference where the elements are located actually makes in practice. But I still think that fitting wet UFH pipes us the way to go, then from an educational viewpoint, you can play about with different heat sources later.

That may be an issue with one particular company, but the same is true of a few mass building companies too.

That is probably a good thing, they have more knowledge. Got to be better than many local builders that have limited knowledge.

Funny how people have different favourite equations, mine is Newton's Law if Cooking. I would type it properly if I switched auto correct off on my phone.

When I did my surveyors course I seem to remember that you had to get online quite quick after gathering the data to get accurate readings, that was in 2006. Did manage to map the halls of residence at Exeter university to within 100mm. Not bad for a first go. Got over 90% in that assignment.

Ah, that makes sense, my least favourite of the equations.

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?

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.
