Hydronic Kickspace Heaters
Kickspace heaters are designed for use with forced hot water residential heating systems. They feature a copper tube, aluminum finned heating element, and an electric motor and blower with a unique cross-flow design. These units deliver a comfortable stream of warmed air at or near floor level and are compact for easy installation. The Type K heater is ideal for horizontal floor installation in enclosures like kitchen counter cabinets or bathroom sinks. They are suitable for radiant systems with a low-temperature aquastat set to turn on at 110°F. Type W is for vertical mounting, recessed in wall studs, with upward air discharge through a flush-mounted, louvered front panel. Type F is for surface-mounted wall units, with air discharged evenly upward through a louvered front panel. All models utilize heating elements with 1/2" nominal (5/8" O.D.) copper tube connections and a 115V electric blower motor. Each unit is interwired with a 120°F (49°C) reverse-acting aquastat that ensures operation only when hot water is circulating. These units are not intended for one or two-pipe steam systems. For gravity-fed systems, a separate circulator pump is recommended for the kickspace heater.

Coils tested at 150 PSI.
*Based on 65°F entering air temperature with fan at high speed, including the heating effect factor. Ratings reduced by 15% at low speed.
**Blower operates at water temperature above 120°F with standard self-contained aquastat. Optional low temperature aquastat available for low temperature applications.
Supply and return connections are 1/2" nominal. Units are not recommended for use with steam.
Standard Aquastat Range 120°F - 105°F

NOTE: In an up feed system, the unit is located above the hot water supply line. In a down feed system, the unit is located below the hot water supply line.
For One Pipe System Down Feed, two directional flow tees should be used, spaced 12 to 18 inches apart. The directional arrow on the directional flow ‘T’ at the return side should point towards the supply directional flow 'T'.
Maintenance and Service
Properly installed, the Kickspace heater requires minimal attention. The heating element is constructed and tested to be durable and non-ferrous, requiring no service. The cross-flow blower is engineered for 10,000 hours of bearing life. As with any electrical rotating device, a yearly inspection and cleaning is recommended. Air movement can cause dust and lint accumulation on rotor blades and air passages. Regular cleaning with a vacuum cleaner tool is advised, with frequency determined by prevailing conditions. Ensure the air grille is not blocked by foreign objects or materials.
