Why Bosch is your best choice
The US Department of Energy says that standard residential tank storage water heaters are the highest energy consuming appliances in the home only trailing heating and air conditioning systems. Think about it. Then ask yourself, how old is the water heater in your garage, attic or basement? If it’s a traditional tank style water heater and more than eight years old, it’s using more energy than your refrigerator, dishwasher, washing machine and dryer combined! It’s time to upgrade.
To help identify the Bosch water heating solution that’s right for you, refer to the Product Comparison Guide in this catalog or visit www.bosch-climate.us and put the
Bosch Sizing Calculator to work for you!

Choosing the right
Bosch product
There are many factors that go into selecting the right Bosch water heater: the number of people in the home, type of showers and tubs, water pressure and geographic region. To make the process easier, we offer
the map and flow-rate table below as well as a new Bosch Sizing Calculator at www.bosch-climate.us.
1.On the map, determine the ground water temperature in your area.
2.In the corresponding column select the Bosch water heater based on how many fixtures you’ll be running at the same time.
Example: A homeowner in Miami, Florida is considering the C1210 ES. The ground water temperature in Miami is 77°F which means this family can run up to 5 showers at the same time.

Calculations based on 120°F Set Point temperature, 107°F shower temperature, 2.5 GPM showerhead flow rate, 1.5 GPM sink flow rate, adequate water pressure and gas supply. Variation from these parameters may alter actual performance.
GPM shown is the hot water flow rate at 120°F Set Point temperature.
