i want to get a ground heat pump, there is common to have a bore well in our area that we can get fresh water out of. i want to know if there is a calculator or something that would tell me if its possible and depths/temperature i can expect out of the system.. i already have 5 kw solar setup and expecting to install 200-300Litre solar water heater but a ground heat pump should be useful in winters when the sun is out and electricity gets out. currently we have 0 house heating, we only use insulation and personal heaters to warm bodies so if i could have a ground heat pump get the house temperature up, that would be great
