FAQs

Your questions about hydronic unit heaters, answered.

A hydronic unit heater is a heating system that uses hot water or steam from a boiler or heat pump to generate heat, which is then distributed through a fan to warm a specific area.

Sizing a hydronic unit heater involves calculating the heating requirements of your space based on factors such as square footage, insulation quality, and local climate conditions. Our account managers can assist you in this process using our advanced selection software.

Hydronic unit heaters offer efficient and consistent heating, are highly durable, and can be integrated with existing hydronic heating systems, making them ideal for various commercial and industrial applications.

A hydronic unit heater works by circulating hot water or steam from a boiler or heat pump through a heat exchanger. A fan blows air over the heat exchanger, distributing warm air evenly throughout the space. 

The primary difference is the heat source: gas unit heaters burn natural gas or propane to generate heat, while hydronic unit heaters use hot water or steam from a boiler or heat pump. This makes hydronic heaters ideal for buildings with existing hydronic heating systems.
