Combination water and space heating systems use a high efficiency water heater or central boiler to supply heating energy to the space heating system while still meeting the needs for domestic hot water. The space-heating component can be accomplished with either a forced air system or a radiant heat system. A forced air system can either use hot water piped to individual fan coil units in each unit or the hot water can be sent to a central heat exchanger and fan coil unit that then sends hot air to the individual units.

Heating, ventilating, and air conditioning (HVAC) systems should provide comfort as efficiently as possible. Equipment sizing, system design and installation will all determine the overall efficiency and performance of an HVAC system, and how well the system is maintained will determine how quickly that efficiency degrades.
