Bosch Tankless Water Heater
Bosch tankless water heaters are some of the best tankless water heater units currently on the market. Unlike other top brands, such as Noritz, Rinnai, and Paloma, Bosch tankless water heaters have been designed specifically with the US market in mind. As a result, they tend to be easier to install than some other brands.
Gas and Electric Models
Unlike Noritz and Paloma, which only have gas tankless water heaters, Bosch offers both gas-powered and electric-powered tankless water heater models. Like other brands, Bosch's gas-powered tankless water heaters are able to provide an endless supply of hot water for multiple showers and appliances in a home. These models are ideal for larger families.
Although not as well known as gas-powered tankless water heaters, electric tankless water heaters are actually far more energy efficient (98% efficient, compared to the 80 – 84% efficiency of a comparable gas-powered model). However, the Bosch PowerStar AE125, the larger of the two electric tankless water heaters, provides only 3.7 gallons of hot water per minute. At 105 degrees Fahrenheit, that means consumers can use the water heater to provide heat for just one shower at a time. The Bosch electric tankless water heaters are ideal for someone living alone or with just one other person who doesn't need to shower at the same time.
Bosch AquaStar 2400ES Gas Tankless Water Heater
The Bosch AquaStar 2400ES is Bosch's flagship model. With an efficiency rating of 82%, it is not as efficient as some of its competitors, but it still qualifies for a Recovery Act tax credit, making it a smart purchase for most families. As Bosch brags on its website, the AquaStar 2400ES can save your family up to 50% on your monthly energy bills. If you get the federal tax credit, plan on staying in your home for more than a few more years, and use a lot of hot water, the Bosch AquaStar will quickly pay for itself.
Point-of-Use Bosch Products
Bosch's Ariston Mini-Tank Point-of-Use tankless water heater installs directly at a sink to provide instant hot water. Electric powered, the Ariston Mini-Tank can be installed in a small, enclosed space with zero need for any type of ventilation (unlike the large, gas-powered AquaStar). Point-of-use tankless devices eliminate any need for wasting cold water while you wait for the water to warm up. Another way to use Bosch's point-of-use models is to place it in-line with your main water heater. By the time you exhaust the supply in the smaller, point-of-use water heater, the larger water heater is ready to start providing hot water for other applications. You can think of this method of using a point-of-use tankless water heater as the “hybrid car” of the water heater world.
