Louvers for hydronic wall and ceiling unit heaters replace damaged or worn louvers. They mount on heaters to point warm air in the desired direction.

OSHA fan guards for hydronic wall and ceiling unit heaters protect workers from injury by preventing accidental contact with the heater's fan blades. They cover the blades and provide the required level of safety when heaters are mounted at a height less than eight feet. These guards cannot be used with a diffuser on the same unit.

Diffusers for hydronic wall and ceiling unit heaters spread the flow of warm air from the heater and limit the throw of air away from the unit, allowing the heat to be distributed in the immediate area. They attach to the heater. These diffusers cannot be used with OSHA fan guards on the same unit.
