Electric heated driveways.?

[LandcruiserLad]

Has anybody an experience with these electric heat pads you can lay under tarmac.
I have a steep driveway and power nearby.
based in Scotland, normally get around 1 week of snow a year.. but who knows what’s coming.

I have under tile heating in a bathroom, but it’s too expensive to use and I suspect this product may be as well.

 

[LandcruiserLad]

I’d probably only need it turned on for 30 minutes?

I'd save your money and buy salt.

Would that work on concrete as iv a pretty steep yard and milk tanker morning can be fun if its frosty

How big is your drive? Other problem might be water thawing and then freezing when you switch it of could be very slippy.

Sounds ideal If it can be linked to a rhi scheme

it’s about 80 metres long ..
..you might be right.
Wonder what it would cost me roughly to have it turned on for 12 hours?
I’ve got some solar panels (20kw)
These would help too I guess. (I’ve no idea how much)

I think a unit (1kilowatt hour) is roughly 15p, so @300watts/m2 it will cost 5p per m2 per hour. So assuming your drive is 3m wide it would use £144 in 12 hrs.

happy for someone to check my figures, but I think you would remember to switch it off.

Buy some rocksalt and sprinkle it on with quadbike and spinner? If the tanker can't make it up the hill get a tractor and strap to help him.

If your drive is that steep then why does water even have a chance to freeze?
maybe drainage is more of something you need to check into, or a really good snow-plow. Detours?

 

[LandcruiserLad]

Snow falls on the ground (even on a slope)
Inevitably it gets compacted and doesn’t get a chance to thaw before the following nights frost.
A snow plough would ruin my drive and a detour on a driveway is daft.
I just wondered if anyone had any experience of these heated driveways?

In Denmark, people like petrol stations had walk behind rotovator type machines with a brush at the front, if the area they had to clear did not warrant mini tractor and brush

I believe the Mound in Edinburgh has under tar heating

just looked at a system which requires 300w per sq. Metre
so if your drive is 80 metres by 2.5 = 200 sq. M.
that is going to need 200x .3 = 66kw or 66 units per hour at 15p that is roughly £10 an hour to run
But I think it needs turning on before the snow comes. You will also have to dig up the concrete and relay with a cably run through. No idea of cost.
I would guess if the snow is that bad , your panels will be generating little or nothing

Is there burners for burning tops of potatoes or something like that that mount on 3pl that you could drive down lane with

I think it would be cheaper to put a polytunnel down the drive to keep the snow off.... Still, compared to laying 200m2 of tarmac, the cost of the heating might not look so bad

some interesting stuff here perhaps. https://www.heatmat.co.uk/wp-conten...-Mat-50W-Snow-Melting-Cable-Factsheet-Web.pdf
