I re-energized my house last year using German subsidies.
Retooling with a heat pump would have been much too expensive.

But I've been thinking a LOT about heat pump (in this case geo-thermaly supported) technology. Why ain't it the silver bullet we've been looking for?

The only answer I have is that you can't bottle it and sell it to your neighbor. If you use it in your own home, you might "save" money in the long run. But you can't "make" money by producing electicity and putting it back in the grid.

Or does anyone have a way of using a heat pump to create electricity or charge a battery? Sort of a refrigerator in reverse??

Thanks, Dom
