Bosch Therm 830ES NG (Natural Gas) Tankless Water Heater

At 175,000 maximum BTUs the Bosch 830 ES NG (Natural Gas) is our highest capacity non-condensing tankless water heater. The Bosch Therm 830ES-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.

The Bosch Therm 830ES-NG is the direct replacement for the Bosch AquaStar 2400ES-NG and the Bosch ProTL 175N and is the closest replacement heater for the Bosch Protankless GWH 635 ES NG and the Bosch AquaStar 2400E NG and the Bosch AquaStar 250SX-NG (the Bosch Therm 830ES-NG is 7 inches taller, 2.5 inches wider and 2.75 inches deeper than these older models).
