Hot Air coil

Last crawled date: 1 year, 11 months ago

A Hydro-Air system is a combination of a hot water and a hot air system. This type of system incorporates a hot water boiler, either oil or gas fired, which heats water and sends it through pipes to a coil in an air handling unit. As hot water heats up the coils, a blower then passes air over the coils. This air is then distributed throughout the home via a duct system. The rooms heat up very evenly because the air is heated to around 120ºF to 140ºF. The air is also not dried out as much as a regular forced hot air system due to the regulated coil temperatures. The same ductwork is also used to distribute cool air if an air conditioning unit is also attached.
