Use an outdoor wood furnace in connection with a hot tub heat exchanger or a swimming pool heat exchanger to heat your pool or hot tub.

You can use an outdoor wood burning furnace to heat your swimming pool or hot tub.

The outdoor wood boiler has a second set of ports, standard. You can use the pump you are using for your home heating system to heat your pool when you are not heating your home.

The easiest way to do this is to put a Y connector at the pump so that you can switch it to send water to the home during the winter and to the pool in the spring. The alternative is to mount the second pump on the provided second set of ports that comes free with the furnace.

An extra set of ports is available if needed.

This is a simple diagram showing how a pool and spa kit is hooked up. The second picture shows all of the parts, excluding the hot tub heat exchanger or pool heat exchanger needed. This kit will keep your pool temperature at within one degree.

The shell and tube pool and hot tub heat exchanger is shown in the third picture.
