Quick Answer
You can use a wood stove with existing plumbing for hot water, but it requires specific setup and equipment to ensure safe and efficient operation.
Choosing the Right Equipment
To use a wood stove for hot water, you’ll need a dedicated wood-fired water heater, such as a thermosiphon or batch heater. These units are designed to safely and efficiently transfer heat from the stove to the water. For example, the Thermosiphon Water Heater by EcoHeat can handle up to 100 gallons of water and is designed for use with wood stoves.
Installing the Wood Stove Coils
The wood-fired water heater connects to the wood stove via a coil, which is typically installed inside the stove. The coil is usually made of a heat-resistant material, such as stainless steel or copper, and is designed to withstand the high temperatures of the stove. When choosing a coil, consider the size and type of your stove, as well as the specific requirements of your water heater.
Setting Up the System
To set up the system, you’ll need to connect the wood-fired water heater to your existing plumbing. This typically involves installing a mixing valve to regulate the temperature of the water, as well as a separate cold water supply line to prevent scalding. It’s essential to follow local building codes and regulations when installing a wood-fired water heater, and to consult with a professional if you’re unsure about any aspect of the installation.
