Bosch GWH C 800 ES

This new C 800 ES model is another top performing, fully condensing gas tankless water heater from Bosch. This model offers high flow rates, efficiency and the most advanced features in tankless technology, yet requires only 199,000 BTU/Hr input. The 1050 ES produces lower NOx emissions – well ahead of the 2012 Low NOX emissions standards set by SCAQMD (California’s South Coast Air Quality Management District), and can be cascaded up to 24 units, making it an ideal fit for all your commercial applications.
