Wood Stove Solar Kits

How it works:

Water is heated by collectors, pumped into the stove when solar energy is available (sun is out).  When the sensor detects a difference in temperature, the pump comes on and remains on until tank temperature is achieved or no more sun is available.  The system is freeze proof because all of the water drains back into the furnace when the pump is turned off by the automatic controller.

How an indirect drain back solar water heating system works:

Water is heated indirectly through a heat exchanger contained in the drain back tank. The system utilizes two circulation pumps. One pump circulates water through the solar collector and back to the exchange/drain back tank. A second pump simultaneously circulates water from the solar storage tank into the exchange/drain back tank transferring the heat from the water that is being circulating through the solar collector(s) to your hot water heater. The system is freeze proof because all the water in the solar loop drains down into the small heat exchange/drain back tank when the solar circulation pump is turned off by the automatic controller. With no water remaining in the solar collector(s) or solar plumbing, no freezing of the system can occur.

How an indirect Glycol solar water heating system works:

Glycol (non-toxic antifreeze mixture) runs through a system of piping, connected to the solar collector and at the other end to a holding tank. The anti-freeze is pumped through the closed loop system, where it is heated in the solar panel then has its heat transferred to water in a water tank, similar to the tank in any regular water heater.  The water is then transferred to your hot water heater.
