The K120 from Beacon Morris is a Twin Flo III series Kickspace Heater w/ 8425-12990 BTU/Hr range. It saves space and is an alternative to hot water baseboards. This item is a small device primarily used in horizontal floor installation. For example, they fit easily under kitchen cabinets, or bathroom sink enclosure. They are ideal for radiant systems with the use of a low temperature aquastat designed to turn the unit on at 110F.

The new Beacon Morris Twin-Flo III models offer improvements in heating capacity, quiet operation, appearance and reliability. The models are designed for fast and easy installation. Sealed, triple ball bearing construction provides protection for the motor and fan. This allows years of quiet and reliable service.

Beacon Morris Kickspace Heaters work with the home's hot-water heating system to keep hard to heat areas warm and comfortable. You don't need a boiler to stay warm. Twin-Flo III units can provide spot heat using the domestic hot water heater as a source of heat.

The Beacon Morris K42 has heating elements with 1/2" nominal copper tube connections. Its 115V electric blower motor interwired with a 120F reverse acting aquastat that prevents operation until hot water is circulating. Optional low temperature aquastat available for low temperature applications. Standard Aquastat Range 120 - 105 F; Low Temp Aquastat Range 110 - 95 F.
