King’s HT series kick space hydronic heater uses the energy from a building’s existing hot water source to offer efficient, whisper-quiet operation and the ability to reduce utility bills with individual room control. By installing hydronic heaters in every room, you can easily heat only the areas in use and conserve energy. Uniquely designed to add heat to areas of the home previously thought not possible. With a compact, space-saving design the HT heater can be inconspicuously installed in the kick-space area at the base of kitchen and bathroom cabinets, under window sills, or even in stair risers, providing warmth and comfort to formerly troublesome areas.
