Can you use compost to heat a greenhouse?

While both worm and cold composting are excellent ways to reduce waste and create soil additions, hot composting is the only form of composting that will provide heat in a winter greenhouse. Within 24-48 hours the temperature in the center of the pile will heat to 141 to 155 degrees Fahrenheit.

How do you capture heat from compost?

Diamond Hill captures the metabolic heat produced by microorganisms during aerobic composting, through a negatively aerated fan system, and blows the hot compost vapor (110-170ºF) against the heat exchange system to heat water for radiant floor heating, feed preparation and sanitation of equipment.

Does compost generate heat?

Compost heat is produced as a by-product of the microbial breakdown of organic material. Compost managers strive to keep the compost below about 65°C because hotter temperatures cause the beneficial microbes to die off. If the pile gets too hot, turning or aerating will help to dissipate the heat.

What temp is too hot for compost?

160°F
Above 160°F, compost is too hot. Few thermophilic organisms are able to get much done when their environment is too hot. If left above 160°F, bacteria will cease active decomposition, which in turn will render the pile inert. [Tweet “Above 160°F, compost is too hot.
