Off Grid Home Forums Technical Discussion Off-Grid ground source heat pump? Re: Off-Grid ground source heat pump?


Well, (a deep subject for such a shallow mind as my grandmother used to say) I suppose water would need antifreeze in it. I’m not sure pure antifreeze is necessary. As for the wells, have you looked into cheaper options for drilling your own wells? There are very small hand operated well drilling equipment on the market available. Also there are point driven wells. These are where pipe is pile driven into the ground. Of course this only works in anything but rock and will only go so deep. There are 3 point hitch drilling rigs for tractors as well. If you couldn’t buy one for $5K then maybe you could rent one.
