Garage is cozy, now what about my greenhouse? I want to keep temperatures comfortable in my wood-stove-heated garage. I am also trying to heat my greenhouse in Iowa via insulated ducting buried underground a short distance between the garage and greenhouse. So, I’m stealing the garage heat and sending it to it’s oblivion in an un-insulated greenhouse.
The greenhouse was already in full production when I installed the ducting so burying it under the beds wasn’t an option. Instead. the duct pops up in the greenhouse like a submarine periscope and is fitted with a centrifugal fan that is controlled by a speed control and thermostat.
It’s cold here in Iowa and it’s unlikely that the air I’m piping in there will be hot enough to offset the lack of insulation and intense cold I’m dealing with. If I can get just one Bhut Jolokia (Ghost Pepper) to ripen in December this year, then I’ve done something pretty remarkable. The leaves are dropping off the hottest peppers now but the kale, chard, celery, greens, and herbs are loving it.
Next step is to bring the ducting right up next to the wood stove and possibly even attach the duct to a cavity in the thermal mass around the stove or attach it to a heat reclaimer like the magic heater. This will require an additional 30 feet of 6″ ducting which I will most likely need to insulate in order to make sure that it’s able to deliver that warmth all the way to the green house.
