And by the way, my local tax is 1100 Euro. My total electricity bill for the year (which also heats me) is 300 Euro per year. So I'm not going to get into underground heat storage.
I note that lessdewatt is much less rich than me, stingy, who accumulates, houses and gardens !!!
but he is like me, 3 times more taxes than heating !!
Stingy, I plan to make a cheap profit, with the simple unpretentious, vulgar sensor hose under carbonate or plastic sheet and drilling with long extension of small diameter and always the same diameter of cheap hose 100m for less than 30 €.
Imagining simple is much more difficult than being expensive !!!

I hardly need it in savings, just check that it is possible and simple !!
I miss the long extensions of drilling !!!
I insist because the stake is immense with such a simple and effective solution, which is not understood !!!!
The solution is not less watt but use those that you waste without knowing it, those of the sun in summer to keep for winter !!!
Finally the profitability, once functional is perpetual and therefore based on depreciation on my life and that of my children !!!
But stingy I think I can get there for almost nothing, a few pipes, carbonate plates to cook, and a cheap mason's puncher with beautiful extensions not very cheap, water and air under pressure !!!!
It is this simplicity that motivates me, given the challenge in comparison !!
