Bosch Gas Tankless Water Heaters Therm 1210 ES
A Condensing Gas Tankless Water Heater for large sized applications
|
Bosch Therm 1210 ES
|
This is the highest performance, fully condensing gas tankless water heater from Bosch. Unlike
traditional non-condensing models, condensing technology captures heat from the exhaust gas and
uses it to preheat the incoming cold water. This increases efficiency and reduces emissions –
well ahead of the 2012 Low NOX emissions standards set by SCAQMD (California’s South Coast Air
Quality Management District).
This Bosch Therm 1210 ES Gas Tankless Water Heaters is only sold to Licensed Installers.
