carbon footprint. Solar thermal water heating offers
excellent value and optimal performance using high
selective collector absorber coatings. These systems
utilize a berglass collector frame and solar safety glass
for robust and durable construction. Bosch solar thermal
water heating systems provide the fastest hydraulic
collector connection set on market today. Universal
mounting systems are also standard. These systems are
designed to facilitate upgrades for future expansion as
necessary, and reduce installation cost through "plug and
play" components.
The "Bosch Complete" product portfolio also includes
tankless water heating (Fig. 147). Bosch offers the most
ef cient condensing tankless water heaters on the market
- up to 98% ef cient - which are engineered for maximum
ef ciency during peak usage time periods in the average
home.

Compared to competitor models, which reach their
optimal ef ciency during off-peak usage times, Bosch
tankless water heating models offer signi cant savings on
utility bills through clean, ef cient use when homeowners
need it most.
Bosch tankless water heating models feature patented
heat exchangers with built-in turbulators that reduce scale
for optimal, long lasting performance. Dual-fan and fully
modulating vertical burner designs achieve an "even"
ame pattern preventing hot-spots and corrosion which
reduce operating ef ciency and the life of the tankless
units.
Bosch features the only condensing ASME certi ed
tankless unit on the market with most models meeting
2012 Low NOx requirements. A variety of models offering
140,000 - 225,000 BTU/hr maximum inputs are available.
These tankless units are all compact, offering easy access
Data subject to change
and 100% serviceable parts, and all have a 20-Year
estimated life expectancy. Indoor and outdoor models are
both available with freeze protection.
Bosch also provides peace of mind to customers with our
15-year limited residential heat exchanger warranty for all
tankless water heating models.
Finally, the "Bosch Complete" product portfolio also
includes gas condensing boilers (Fig. 148). These
products are ideal for residential space & water heating
applications. They are available in 6 condensing wall-
mounted models with con gurations ranging from 57.2 to
151.6 MBH. All models offer high ef ciency - up to 98.7%
with low temperature applications (up to 96.1% AFUE).
Additionally, units are Energy Star® rated with reliable
performance & low emissions. Special insulation within
the systems ensures ultra quiet operation, and units are
all built with a removable front panel, direct access to
the heat cell and a plug-in diagnostics module for easy
servicing.
Bosch gas condensing boilers are equipped with a
modulating fan assembly allowing the boiler to achieve
optimal combustion - ensuring high ef ciency throughout
the boilers operational range. An aluminum-silicon heat
exchanger offers increased exibility versus traditional
stainless steel with highly durable, corrosion resistant
heating blocks designed to optimize clean burning
combustion.
Bosch gas condensing boilers offer a high strength, plated
stainless steel double-pass secondary heat exchanger and
burner ensuring consistent temperature output based
on demand. Digital thermostats and outdoor reset boiler
controls are programmable up to six switching times
throughout the day. These controls provide instant access
to hot water and heating control with an exclusive keypad
safety lock feature preventing unwanted tampering.
