One of the spendy homes I shot a couple years ago for the realtors had a full driveway with coils, probably about 200 yards long and 12 foot wide, Ran off a 3 phase service from the garage, he said it would burn about 22kw and cost around 600 bucks for 8 hours. Cray cray
I need a heated driveway, if I don’t keep that fucker clear to the concrete I can’t drive up it.

I wonder how deep you would have to dig to just have recirculating water use latent ground heat maintain surface temps above freezing. I don't exactly live in a cold climate but the 4' deep slab of my basement floor stays above 45 degrees no matter how cold it gets outside.

Depends, but stable year-round ground temps are about 3m down. Youtube is full of people doing this for greenhouses in the winter with air. Obviously a different problem with water and melting snow, but I imagine it could be done. Seems like a fairly straightforward engineering calculation.

For example:

Use hot water, :brows:
I know a guy who rigged up a giant outdoor furnace and had buried water lines into his house. It was basically an open boiler that had circulation pumps heading to different zones. In the zones he had big radiators with fans behind them.

Could see the same setup for driveways. Just slog out and fire up the wood stove, wait for the water to melt, turn on the circ pumps and watch the snow melt away..

Geo thermal with a buried cistern and circulation pump is the real option, helped a buddy instal his and it works flawlessly, but you need to have your pex about 2 inches under the surface of your concrete, most peeps dont use concrete.

That's what's up. I want to build something similar. I wonder if I buried them under a gravel driveway if that would be effective? I know buried cisterns have some restrictions due to the potential for people and animals falling in and drowning.

Gravel/asphalt wont hold the heat and will dissipate as compared to concrete or pavers, the cisterns are an enclosed poly tank but buried well below the frost line

I think I’ll stick with using my snowblower followed with a shovel to get down to the concrete. I picked one of these up 2 years ago, it speeds up the process.

There’s a guy here that does augmented reality stuff with a sandbox and the projector projects rainfall and water shed stuff onto whatever landscape you have made in the sandbox, so he requires a special high grade of sand to make it all work.
Sand is a euphemism, right?
