Can I use this to heat the ground inside my greenhouse minus the backup heater? I want run piping underground inside the greenhouse and let the heat radiate upward

[@aldojansel9439]

what kind of material is the absorber plate?

[@canadianbro9327]

Silicon is mostly used material for solar panels, since it's cheap and easy to get (from sand) there's no other problem 😊

[@matthewmullin8168]

@@canadianbro9327 these aren't solar panels; they're just black sheets that absorb sunlight and convert it to heat. I would assume it would be some kind of metal like aluminum coated with a dark pigment like graphite or a metal oxide.

Our British government wishes to give this free of charge through the grant Green scheme but over the past 10 years I have so many bad dealings with these so called grants I ended up buying my own stuff eg boilers cavity wall loft insulation etc so I wouldn't get anything from the British government/Council... Ever

Does it directly heat water or is it some other liquid?

[@RedondoBeach2]

I watched another video where they indicated that glycol is used as a heat exchanger to heat potable water. if that's the case, it makes sense, since glycol also prevents freezing. However, the video I watched was a system that might have been installed in Africa, based on the comments from the video. I mention this because I do not know if systems in Africa are designed similar to those in the U.S.

DIY. It is so simple to build.

Thanks a lot for this nice demonstration!

Why not have a black tank in the roof instead of solar water heater that cost a lot

[@537331208]

It’s already been discontinued by Bosch.

[@RedondoBeach2]

Were the solar panels a bad product? Do you know why they were discontinued?

[@537331208]

@@RedondoBeach2 I can only guess that there wasn’t a government rebate for them any longer so not many people could afford them.

Solar thermal is typically now combined with solar PV - keeps the PV panels cooler, which helps them to generate more electricity. Only slightly more expensive to but, and you get two lots of free energy for the price of one. Solat thermal panels are widely available in Europe though, so maybe this was just a blip, a US thing during the MAGA years.

Good work

Looks complicated and expensive.

[@بوفارسبونورا-ص7ه]

It is costly, complicated, and requires a skilled technician to repair and maintain it. It is also large in size and distorts the roof view.

[@canadianbro9327]

But still it reduces the dependency on fossil fuels. So one of the main problem "pollution" is solved ✔️

[@بوفارسبونورا-ص7ه]

@@canadianbro9327 Is the pollution problem solved by increasing the cost ? Increased cost means increased poverty. This is not the best way to deal with pollution . Reducing pollution is by controlling overpopulation and by stopping deforestation .
