A hot water boiler system will heat the water to 180 degrees fahrenheit on a cold day and then a pump will pump the hot water through a piping circuit or a piping loop to deliver the hot water to heat exchangers such as a hot water coil inside an air handler vav box or fan coil unit where air is passed over the coil. Chilled water hot water steam refrigerant refrigerant heat recovery coil runaround loop heat recovery based on initial input conditions the programs will calculate capacity air pressure drop and water pressure drop for all water coils and steam pressure drop for steam coils including coils with copper fins or coils. Saves energy compared to traditional furnaces when integrated with rinnai s highly efficient tankless water heaters or boilers that can deliver home heat and domestic hot water.
