It’s snowy outside and the temperature is 0ºC and falling. We are living in an insulated room, in our barn, for the winter. This summer we will build a cabin in the forest and install a wood stove but for now we manage to heat with a small, flameless, catalytic heater used normally in RVs. It is good but costly to use. We don’t want to risk the fire hazard of installing a wood stove in our 100 year old barn, so we do what we can to improve our heating system without spending too much money or going on the grid. Heating air is very inefficient. Heating masses such as water is far better. The warmed masses retain heat for a far longer period of time than air and emit a healthy, radiant heat. In order to capture and store as much as possible from the heater, we built a stand to hold a pot of about three gallons of water over the heater. Heat rises and we realized that a lot of the heat is trapped over our heads near the ceiling. In order to capture the “lost heat” near the ceiling and store it, we placed gallons of water no further than 10 feet away from our heat source on the upper shelves around the room. It seems to work. It’s now easier to warm up the room and it stays warm longer.
