The Hubbell Tankless HX/TX is a compact commercial tankless water heater. HX/TX uses only as much power as necessary, while delivering accurate and consistent hot water temperatures. This on-demand water heater can replace traditional water heaters or work in combination with our storage tanks. The instantaneous thermally efficient design minimizes stand-by heat loss and operating costs. Both the HX and TX tankless water heaters are highly reliable, easy to maintain, compact, and efficient. Factory packaged for trouble-free installation and operation. See the Hubbell Tankless TXA for our ASME option.
