Can I install a hot water coil myself on a wood cookstove?

Choosing a Hot Water Coil

To install a hot water coil yourself, you’ll need a suitable coil, which is typically made of copper, stainless steel, or a combination of both. The coil should be specifically designed for wood stoves and have a sufficient surface area to absorb heat efficiently. A coil with a diameter of 1/2 to 3/4 inch and a length of 24 to 36 inches is a good starting point. Additionally, consider a coil with a high heat transfer coefficient, such as a coil with a spiral or helical design.

Coil Installation on the Wood Stove

First, locate a suitable area on the wood stove for the coil, typically near the firebox or under the cooking surface. Ensure the area is clear of any combustible materials and can withstand the heat generated by the stove. Use a heat-resistant adhesive or a high-temperature gasket to secure the coil in place. Next, connect the coil to your water supply line, using copper tubing and fittings specifically designed for high-temperature applications. Be sure to include a shut-off valve and a pressure relief valve to prevent water damage and ensure safe operation.

Connecting the Coil to Your Water System

Once the coil is installed, connect it to your hot water system, which typically consists of a water tank, a pump, and a circulation system. Use a suitable pump, such as a recirculating pump, to circulate the hot water through the coil and back into the tank. Consider installing a temperature and pressure gauge to monitor the system’s performance and ensure safe operation. Additionally, consider the size of the water tank and the flow rate of the pump to ensure efficient heat transfer and adequate hot water supply.
