  1. It's a warning valid for areas with tectonic activities. But it should have been known in advance, and the flat collectors should have got preference over a deep whole.

  2. A heat pump is about to raise Faktor 4 more heat energy, from one kWh electric energy. So if your price of electricity is less than 4 times higher than your price of gas per kWh, it's worth it in matter of consumption. So you have to speculate for the next 20years, how these prices develop, right now, it looks like oil and gas raise quicker, and a heat pump is universally worth the investment.
