Bosch 2400ES instantaneous tankless water heater
Bosch Tankless Water Heater 2400ES
Bosch AquaStar 2400ES
The Bosch AquaStar 2400ES Direct Vent (Room Sealed Combustion) hot water heater is powerful enough for 2 major uses at once. The Bosch 2400ES has quickly become the tankless water heater of choice for families needing to operate two major hot water applications at a time. With an average life expectancy of more than 20 years, energy savings of up to 50%, and an endless supply of hot water, your family will thank you for years to come. Easy to install with multiple venting options, the Bosch AquaStar 2400ES is the right choice.


Bosch AquaStar 2700ES instantaneous tankless water heater
Bosch Hot Water Heater 2700ES
Bosch AquaStar 2700ES
The Bosch AquaStar 2700ES Direct Vent (Room Sealed Combustion) hot water heater is powerful enough for 2 major uses at once (and up to 3 in warmer climates). For example - run two showers at once, or a dishwasher and shower at the same time. The Bosch 270ES can be vented up through the roof or out through a side wall with 3-inch sealed stainless steel pipe or mounted outside in warmer climates with the Optional Outdoor Kit. This unit is 82% efficient and about 33% better than a new tank. The Bosch AquaStar 2700ES comes with a 12 Year warranty on the heat exchanger and 2 year warranty on other parts.



Bosch 1600 Tankless Water Heater
Pictured is Bosch Model 1600
Bosch Aquastar 1600H
The Bosch AquaStar 1600H Tankless Water Heater utilizes Bosch's revolutionary hydro-generated ignition system incorporating hydro technology into a domestic water heating appliance. Like a hydro dam producing electricity, the 1600H system ignites the burners when water is flowing without the need for electricity or batteries. This patented technology is only available on Bosch AquaStar tankless gas water heaters. The 1600H water heater replaces the 125HX.


Bosch Aquastar 1600P
The Bosch AquaStar 1600P is the right size model for most homes requiring a single major use at one time - thus this is an ideal household water heater. The 1600P offers the same high performance of the 1600H but has a standing pilot. The Bosch 1600P water heater replaces the 125B.


Bosch Aquastar 1000P
This small Bosch gas tankless water heater is ideal for cottages, camps, and other specific applications where a small volume of hot water is desired. The compact size of the 1000P means you save valuable floor space and is available in both natural gas (NG) and liquid propane (LP). This water heater replaces model 38B.
