What’s the Best Location for a Wood-Fired Water Heater?

Situating the Water Heater

When choosing a location for your wood-fired water heater, it’s essential to consider its proximity to the wood-burning stove. A distance of 3-5 feet is ideal, as it allows for efficient heat transfer and minimizes heat loss. Typically, wood-fired water heaters are installed near the stove, with some models featuring a thermosiphon system that uses the rising hot water to circulate it back to the tank. This setup ensures that the water heater is always in contact with the hot stove coils.

Water Heater Orientation

The orientation of your wood-fired water heater is also crucial for optimal performance. Ensure that the water heater’s inlet and outlet pipes are oriented to allow for easy water flow and minimal kinking. A common setup involves installing the water heater directly above the stove, with the inlet pipe connected to the stove’s chimney and the outlet pipe leading to the household plumbing system. This orientation helps to create a natural thermosiphon effect, which reduces the need for pumps and other mechanical components.

Selecting the Right Water Heater

When choosing a wood-fired water heater, consider a batch heater or a DIY setup with a large tank and stove coils. Batch heaters are designed to heat a large volume of water quickly, often using a combination of stove coils and a thermosiphon system. DIY setups can be more cost-effective and offer flexibility in design, but require careful planning and execution to ensure safe and efficient operation. Regardless of the type, ensure that your water heater is properly sized for your household’s needs and meets local building codes and regulations.
