1. Tankless Water Heater
The Rheem tankless water heater serves two purposes in the hydronic system: it provides continuous hot water for use throughout the home. When a call for heat is made, the tankless water heater also acts as the heat-source for air handler, providing both hot water and heating for the home simultaneously.

2. Hydronic Air Handler
The hydronic air handler features a hydronic heating coil in place of either electric heating elements or gas-fired heat exchangers. When in heating mode, the hydro pump circulates hot water between the tankless water heater and the hydronic coil.

3. Cooling Coil
In Cooling mode, the cooling coil operates the same as any other Rheem heating and cooling system.
