Warming

I got an idea to move the warm air from around the furnace into the greenhouse. And guess what? It really works well! :) I will add the drawing later to share the idea. The same furnace is heating up the floor and air at the same time. The hoses will be moved to enter the greenhouse directly to prevent any wasting of the heat. In the future the waste heat will warm up the greenhouse too. The barrel looks quite small but it's actually 200 liters.
