The Bosch GWH-260-PN (formerly the Aquastar 38B) model is perfect for small cabins, RVs, and other relatively low-demand water systems. It is not designed for a full-size shower or large appliance operation. It uses a pilot light for ignition and requires no electrical power for operation. The 260-PN is approximately 29x12x9 inches, making it ideal for applications with limited space. You only need sufficient wall space to mount the unit and be able to install an exhaust vent to the outdoors.

The newest tankless water heater from Bosch features built-in power vent (allows venting horizontally), an electronic ignition and no standing pilot. Sold with FXHOOD. 70 degree rise at 2.6 gpm

The Pro Tankless™ by Bosch 425 HN incorporates a revolutionary hydro-generated ignition system, allowing the water heater to operate without a standing pilot, electricity, or a battery. A small turbine in the water heater uses the energy from the flowing water to ignite the spark. This technology is patented by Bosch and is available on the Pro Tankless™ by Bosch 425 HN tankless gas water heater. (Operates only one major appliance at a time)

The 635 ES requires no special tools to install or maintain. It's compact size and sealed combustion enables installation in small spaces. 70 degree rise at 4.2 gpm
