The fan coils in each area creates the heating and cooling effect. Hydronics is the quietest and most comfortable form of heating and cooling. The micro-cogeneration is perfect for radiant floor heaters and provides hot water for washing and bathing. The Micro-cogen units are also available as split and unitary or central systems. This translates into the use of 1-inch plumbing pipes as opposed to using 8 to 16 inch air ducts.
Much less energy is required to circulate water as opposed to air.
The water pump and small fans in the heat exchangers will consume less energy than the large blower required to force air through out the house. Superior temperature control from room to room. Each room with a fan coil unit can utilize its own precision thermostat and fan speed control. Rooms not requiring environmental control can be completely shut off. Circulating water in place of air provides two distinct advantages.
