Bosch condensing tankless technology
Bosch condensing gas tankless water heaters are ultra efficient systems. Unlike traditional non-condensing water heaters, a condensing unit captures latent condensation heat from exhaust gas and uses it to preheat the incoming cold water, making Bosch condensing tankless water heaters 10% more efficient than a traditional tankless water heater.
- Superior aluminum and copper heat exchanger construction captures 10% more heat energy than a traditional tankless water heater
- Modulating burner design with uniform flame coverage ensures greater efficiency and performance
- Built-in turbulators reduce scale build up
- Digital control panel and the ability to adjust output temperatures in precise 2°F increments is especially important in homes with children and elderly family members
- Clean combustion process achieves up to 98% thermal efficiency and reduces NOx emissions ahead of 2012 SCAQMD regulations
Eligible for up to $1500 Federal Tax Credit (30% of purchase price and residential installation)
This 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
