About the Bosch 120V, Therm Non-Condensing Tankless Water Heater for 2-3 Bathrooms, Indoor - Liquid Propane

With over 125 years of service and dedication, Bosch has become the household name trusted for water heating, plumbing and supply. In addition to carrying the name, Bosch has been known to be the innovator of new technologies to vastly improve water heating. With new technologies such as their heat exchanger burner, the life expectancies of their products have boasted lengths of up to lifetimes. Their commitment to quality and efficiency is exuded today throughout all their products.

The Bosch 660 EF LP is the premier, compact tankless water heater. Featuring a non-condensing heat exchanger, the Bosch 660EFLP utilizes liquid petroleum (propane) as an energy source. Although compact in size, the Bosch water heater produces up to 140,000 BTUs per hour, supplying continuously running hot water for at least a shower and a sink simultaneously. With the tank’s 6.6 gallons per minute capacity at 35°F rise, hot water is reached faster than conventional storage tank water heaters. The 660 EF LP’s ability to heat water is not compromised by high energy usage; this unit has an energy factor of 0.82 and a thermal efficiency rating of 83%! Suitable for both residential and commercial applications, the Bosch 660 EF LP has the maximum temperature of 160°F.

For extended usability, the Bosch 660EFLP can be used in recirculation, solar and thermal configurations to best suit your application. For safe measure, the unit is also designed to be used in altitudes of up to 4,500 ft. Bosch leads the industry with its longest ever warranty, 15-years backing all these great features. With the 660 EF LP’s life expectancy greater than 20 years, and its 100% all serviceable parts, the Bosch 660EFLP may possibly be the last water heater you’ll ever need to buy.
