Heating a greenhouse with compost

Doesn't this look a good idea! Heating a Greenhouse with Compost and Manure | Permaculture Magazine
Hope to own a greenhouse myself one day, and I think this would be my preferred method of heating it - ha ha, let the thieves try and run off with a compost heap!!

I watched an episode on Beechgrove about hot beds but never thought of having one in a GH.

Oh, how I wish I had room for a proper greenhouse. I have the hotbin and 2 horses to produce copious quantities of fresh manure, but I just don't have the space

Rotting manure can produce some serious heat. I have three big compost bins full of the stuff and they are registering an internal temperature of more than 70 degrees Celsius. I have made hot beds in the past but never in the greenhouse. Good idea but remember some bodies got to shovel al that pooh. Not only into the greenhouse but back out again when it been finished with.

One of the oldies on our site fills a polythene bag with grass cuttings and sits his seed trays on it...

scuse me, exacterly what qualifies him to be considered an oldie?

This is a good idea,but is it reliable? my compost daleks temperatures vary a lot.

The trouble with dung heating is the ammonia given off. Kills seedlings.

yep tell me about it. i tried it last year a full batch of sowings got brassed up. had to resow the lot. even my chrysanth cuttings suffered. it got a bit hot. the parrafin heater was promptly dusted off and brought out of its annual retirement.
