At 199,000 maximum BTUs the Bosch 940 ES NG (Natural Gas) is our highest capacity non-condensing tankless water heater. The Bosch Therm 940ES-NG was designed to meet the demands of busy households and offers the premium features you expect from Bosch. This model can be installed almost anywhere thanks to its sealed combustion and dual-fan technology.
It features an electronic ignition system and requires either 3 inch or 4 inch diameter stainless steel vent pipe and can be vented either through the side wall or up through the roof.
This heater is Energy Star rated.
This heater comes with built-in freeze protection and a water filter that is externally accessible, but does not come with a PRV.
