Do you really think anyone will visit you.

Me to, at least the electrons have a closer path to the heart.

I had my testicles checked. Not sure why it was necessary to be a tool maker. They left my tool alone.

Being left handed is probably just as risky.

Why would you need to adjust heating when you are not there, who benefits from that? I got burgled in daylight.

Yep, just give me some cash and I shall tell you what I want to install. Seriously. You need to decide what you want automated, above and beyond what you can already do. So if you need to switch lights on when you are away, that can be fitted, if you want to turn your heating down, when you are away, that can be fitted. But have a real hard think about what is important to you. My personal view is that it is all a nonsense, technology looking for a use.

That looks like a good idea, low wattage and fairly cheap to buy, cheers Oh, it works in the far infra red. At 350 W, 4 old light bulbs would give off more power.

Welcome. First thing to know when it comes to heating, is the heat load needed. This can be either measured with a known heat source, two thermometers and a stop watch. Or calculated from first principles if you know all the details about the construction i.e wall, window/door, floor and ceiling/roof u-values. It is always worth doing this anyway, it takes the guess work out of it.

That is a second hand unit. I would expect the price to be a lot lower.

That is an interesting problem.

Yes please, with names and phone numbers.

I think they can recover the latent heat of fusion from the excess humidity. There are some that have a porous paper element that allows some transfer of moisture, but I don't think there is enough to worry about. Have you thought of putting an extractor hood over the fishtank. Then plumb it into your existing unit.

So glad I never replied, would have got deleted as well.

I would think, without calculating, that variations in the ground makeup, depth of pipework, differences in radii of the loops, water retentions in the soil and any shading on the loop area, would make a larger difference than turbulence within the ground loop.

What does your room by room thermal calculations show?

I worked for a small turbine manufacturer, they made a 5 kW model, cost about £18k 15 years ago. The marketing side wanted to reduce the price, pointed out that if the moving bit was free, they would not get the price much below £12k. You would be better off getting an EV (assuming you drive an ICE car atm). Or integrate a heat pump into you PV and save a few kWh there.

Have you got planning permission for one. Once you have that, then we can tell you small ones are pointless.

What happens if the amount of fluid in the pipes is below the recommended amount? What happens if the heat load needed is only 0.4 kW? Good engineering practice tries very hard to not work at the extreme capability if the equipment.

Have you thought of just putting something like this in a very prominent position.
