Compost bin water heater

Now this is an idea I really like especially as our local council say they are withdrawing green bins next year. Well, not actually taking them away but only emptying them if you pay.

From: Permaculture News, see link below

This is an ideal to make them into compost bins and get hot water. It’s not new idea but this looks interesting. I can see a row of them with isolating valves so that they can be switched on when hot and off as they cool down.

Not sure what the effect would be on the compost, first thoughts are that if you remove heat you slow down the process. I would guess that it depends on how much heat is taken.

It could be another crazy project for next year! Full text of the article is here. (You need to scroll down the page.)
