| The Hot Rod provides an effective way to route water through the firebox or in the warm air duct (plenum) of a wood-burning furnace or stove prior to entering the primary water. It allows you to use the energy from burning wood to preheat water, reducing the primary load on your water heater... and your heating bills. Made of high temperature, corrosion-resistant stainless steel, the compact Hot Rod can be inserted in areas of maximum heat through only one opening in the firebox.
Heats at a rate of 18 gallons per hour with an 80º F temperature rise.
Available in a 24" length. Can be installed by the handy homeowner or a heating contractor.
