Have you ever imagined producing electricity on a wood stove?

How good would it be if you could get warm water along with electricity from the wood stove? This is a realistically possible story. In a simpler way than you thought.

Cooling is the key

I additionally conducted the thermoelectric power generation experiment I performed last time. I made a water-cooled thermoelectric power generation module using a stainless steel pan the same size as that used in the stove. The maximum voltage was 8.22 volts, and the current was 1.1 amperes. So it was able to produce about 9 watts of electricity. I could charge the cell phone with the produced power and this result is very satisfactory compared to the result of the air-cooled power generation module test conducted last time. Two thermoelectric elements were fixed in series on the lid surface of the module, and heat-resistant silicone for high temperature was applied to prevent thermal damage. The module is installed in contact with the bottom of the firewood stove, and the heat from the bottom of the stove is transferred to the thermoelectric element for power generation. The module can be filled with about 4 liters of water, and the radiator submerged in water releases the heat absorbed from the heat source into the water.

Use of warm water

A drain tap is installed at the bottom of the module to design the drained water. Later on, if I added the inlet pipe and installed the pump, I would be able to do hot water circulation heating.
