Bosch AquaStar 1600PS Solar Pre-heat Tankless Water Heater

The Bosch 1600PS Solar Tankless Water Heater is designed to take preheated water from a solar or wood heated system. It is the only Bosch AquaStar Tankless Water Heater that can take preheated water as input!

The "P" in the product name indicates that the Bosch 1600PS has a pilot light for its ignition system. The "S" stands for solar.

The Bosch 1600PS has the same specifications as the Bosch 1600P, except for the fact that it can take preheated solar water.

One common question is whether the Bosch 1600PS tankless water heater can be used WITHOUT preheated solar water. The answer is Yes! So, if you do not currently have a solar system in place but are planning to get one, you can definately install the Bosch 1600PS now in advance of your solar system purchase.

Just like the Bosch 1600P, the 1600PS provides 4.3GPM at a 45 degree F temperature rise and has a low minimum activation rate of just 0.5GPM. Both heaters take a BTU input from 23,400 - 117,000 BTU input. Also, both the 1600PS and the 1600P take 5" double-wall, Type B galvanized venting.

  1. Does Bosch, or any other manufacturer that you know of, make an instantaneous water heater that can be mounted outdoors in possibly freezing conditions, use no electricity (has a continuously burning pilot), and allow solar preheated water?

  2. Stacy,

    The answer is "No" because you have listed too many technical requirements.

    The freeze protection provided on some outdoor heaters requires electricity to run a current over the pipes that helps prevent freezing during occasional overnight freezes.

    We have the Bosch 125BO-NG which uses natural gas and has a continuous pilot, but the freeze protection requires electricity.

    Also, the Bosch AquaStar heaters cannot take in preheated water (except for the Bosch 1600PS, which is an indoor heater).

    Call us at 888.726.9752 for more information.
