Bosch Tankless Water Heaters Used for Solar Thermal Applications
Certain models of the Bosch tankless water heaters are approved and designed for using Solar Thermal. Solar Thermal applications should be set up in conjunction with an indirect tank to maintain a more consistent temperature but the heater can be used for direct solar preheated water. The maximum temperature for the solar preheated water into the Bosch tankless water heater is 140 degrees F. The Bosch tankless water heaters that are approved for Solar preheated water are listed below:
Bosch Therm 830ES
Bosch Therm 940ES
Bosch Greentherm C950ES
Bosch Greentherm C1050ES
Bosch Therm C1210ES
Bosch Therm C1210ESC

Bosch Therm 660EF/660EFO Tankless Water Heaters
The new Bosch Therm 660 EF and Bosch 660 EFO are direct vent units. These units take thier combustion air from the area they are installed in. The 660EF/EFO are compact in design for space saving installations and are only 14" x 20 1/2" x 7". The 660EF/EFO are designed and approved for reciculation and space heating applications. The units have electronic ignition and come equipped with built in freeze protection. The Bosch Therm 660EF vents either vertically or horizontally using 3" or 4" stainless steel venting #AL29-4C.
The 660EF is manufactured in Japan and comes with a different vent connection than the 830ES, 940ES, etc. The 660EF needs to be vented with single wall stainless steel venting and is designed to connect directly to "Bosch Vent". However, a Z-Vent adapter (Part # 2SVSWB03) allows for the use of 3" Z-vent stainless venting to be used. Global Pro Tankless Supply carries the adapter and all the Z-Vent stainless steel venting to install the Bosch Therm 660EF. We are the exclusive distributor for the AQ5EF Side-wall Vent Kit for the Bosch 660EF tankless water heater.
The Bosch Therm 660EFO outdoor unit comes ready for installation and does not require any additional cap or venting.
Without the Z-Vent adapter (Part # 2SVSWB03), the customer would have to purchase different venting ("Bosch Vent") to use for the 660EF.
The Bosch Therm 660 EFO is our most compact outdoor model and is loaded with features you’d expect from Bosch, including freeze protection and built-in high temperature capability (160°F).
The Bosch Therm 660 EFO is a good replacement for the GWH425HNO and the 125BO as these units have been discontinued.
The Bosch Therm 660EF and Bosch Therm 660EFO have an excellent warranty:

- 15 year warranty on heat exchanger if used if recirculated through a storage tank such as the Ariston mini-tank
- 5 year warranty on all other parts

Bosch Therm C1050ES vs. Bosch Pro GWH C800ES
Recently the Bosch model GWH C 800 ES gas tankless water heater was changed to the new model name Bosch Therm C 1050 ES. The model name had changed to reflect gallons per minute (gpm) at a 35 degree temperature rise. So the Bosch Therm C1050ES would reflect a 35 degree temperature rise at 10.5 gpm. Along with this name change came many new features:
- Comes equipped with freeze prevention now.
- Has the capability to accept preheated water up to 140 degrees and is approved for domestic hot water (dhw), solar thermal and space heating applications in conjunction with an indirect tank.
- Has the ability to be cascaded using the Intelligent Cascade Kit for up to 24 units and would produce up to 290 gpm.
