When compared to traditional storage tank heaters, Bosch's line of tankless propane-fired water heaters are almost unbelievably efficient, and incredibly long lasting. With traditional water heaters, heating efficiency can be as high as 78% when brand new, but that rating declines annually as minerals and debris settle on the bottom of the tank. Most tank heaters will also require replacement in 9 years or less.

A quality gas tankless water heater can be expected to last up to 20 years, with almost no loss in efficiency. Also, because tankless water heaters only heat water when it's actually being used, instead of heating a full storage tank 24 hours a day, a Bosch heater can save you hundreds of dollars per year when compared to an electric tank water heater. In addition to financial considerations, with a tankless water heater you never need to worry about running out of hot water. As long as your hot water tap is open, your Bosch 330 PN will keep heating water.

The Bosch Therm 330 PN (formerly Bosch p/n GWH-260-PN) is ideal for small cabins, RVs, and other relatively low-demand residential water systems. It is not designed for a full-size shower or large appliance operation.
Delivers up to 3.3 gallons per minute with a 35 deg F temperature rise. Minimum flow of 0.5 gpm to activate. 75,000 BTU. Non-Condensing.
It uses a pilot light for ignition and requires no electrical power for operation. The 330-PN is approximately 22-7/8" H x12-1/4" W x 8-3/4" D, making it ideal for applications with limited space. Weighs 26 pounds (shipping weight will be higher). You only need sufficient wall space to mount the unit and be able to install an exhaust vent to the outdoors.

Bosch ProTankless water heaters are state of the art tankless heaters with a 15 year limited manufacturers warranty on the heat exchanger, 2 year warranty on the other parts, to protect your investment. A modulating gas valve controls the water temperature, according to your setting, and an included pressure relief valve helps ensure safe, reliable operation. Bosch ProTankless heaters are available in propane (LP) or natural gas (NG) configurations. Please select your preference whn ordering.
