Wood burning automatic swimming pool heater

摘要

A swimming pool heater has a fire chamber with a fuel feeding opening closable by a door which is removable to use the heater as a fireplace. A heat exchanger comprises a continuous length of copper tubing paralleled by an adjustable bypass. Air is supplied through a preheating manifold and regulated by a thermostatically controlled damper. A baffle delays escape of smoke and gases from the chamber.
