The IN.THERM is an intelligent 4kw remote heater for IN.XM controls that integrates electronics directly in its power box. Its long list of features includes a built-in temperature probe and new water flow detection that eliminates the need of a pressure switch. The design of its unique seamless enclosure and cover gasket eliminates all risks of water infiltration. The IN.THERM's clever solid state design ensures years of trouble-free use. It can command multiple power levels on its single element and heat at its highest power only when necessary, reducing the demand on the element and greatly extending its lifespan.
