In a Hydro Air system, hot water is made from a gas or oil fired water boiler, which circulates through a multi-row coil in an air handler. Air is passed over the coil, heated and then blown through ductwork to rooms of the house. The air can be additionally treated with an air filter, electronic air cleaner, or a high performance media filter.
