Bosch Tankless C1210ES

Bosch Therm C1210ES Tankless Water Heater

This Bosch Tankless is the highest performance, fully condensing available from Bosch within the Greater Toronto Area.  A condensing tankless captures heat from the exhaust gas and uses it to preheat the incoming cold water through the use of a secondary heat exchanger.  This nets around a 12% efficiency increase further reducing emissions.

Bosch Therm 1210 is a low NOx compliant system, although that doesn’t  really have a bearing on us here in Toronto and area it is still nice to know that these systems are meeting and exceeding much stricter emission guidelines set out by the state of California. toronto and area bosch tankless sales

This Bosch tankless also only has 4 moving parts which have been designed to be replaced or serviced individually.  The engineers have taken time to ensure that these tankless units stand the test of time and exceed the 20 year expected lifespan.
