I wish I had took pics of this job as it evolved but I wanted to share it anyway.
Had a guy who lived in a valley surround by rock cliffs, he had a home roughly 2000 square feet, a green house or "high tunnel" that he built in a rich valley near his home, it was 32x96. It uses the exsisting soil, you grow in the ground, not in beds. He was also tying a small shack to it where he made maple syrup.
The interesting part of the install was his fuel oil furnace that he had from the late 60's in his home, the fan never shuts off in his home and runs at a very low speed, he said the only time it had been shut off was during power outages, so in the install we used a zone valve, so when the thermostat called for heat the zone valve would allow water in the coil, when it wasn't calling for heat it would simply bypass the coil. It was the first one I had done where the fan never shut off, after seeing it in action and how evenly the heat was distributed in his home, it's def a great way to go. We waited til the furnace got up to temp and ran a couple cycles before we left, house was 72 all over and the high tunnel went from 44 to 62.
I love seeing big jobs come together...
Here is a pic I took as I was leaving, you can see the high tunnel on the right, the house behind, and his future sap shack on the left
