Solar energy is clean, ree and abundant. It is the clear choice orenvironmental and energy minded people. Solar heating becomeseven more compelling when you consider rising energy prices,depleting ossil uels and growing conservation initiatives.

Baxis commitment to nding alternative energy sources hasueled its development o an integrated solar heating system.The Baxi heating system may include Baxi Luna wall-hung boilersto ensure optimum perormance and sustainable comort.

Solar energy is the clear choice for building a better future.

Heating SystemsMaximum Use of

the Suns Energy

The Baxi integrated solar heatingsystem maximizes the sunsenergy by using high-perormanceselective, prismatic collectors.

The Baxi solar collectors are the rightsolution or any application theycan be used to provide domestic hotwater, or supplement pool heatingsystems and low temperature spaceheating via heat exchangers.

A solar water heating systemthat maximizes the suns energytypically provides up to 65% othe annual domestic hot waterheating energy requirements or

a single amily home, dependingupon geographic location.

Quality and

Reliability

To ensure quality and reliability, Baxisystem components are specicallydesigned or solar heating systemsby leading solar equipment suppliers.

Baxi Integrated

System

Baxi has designed the solar heatingsystem to be easily integrated withits boilers. Another solution toensure maximum comort rom Baxi.

Selective Prismatic

Solar Collectors

Baxi fat plate collectors with prismatic glazing andhighly selective coating oer the optimal combination oabsorption eciency (95%) and refective losses (5%).

The solar glazing and absorber are housedin an aluminum rame with eectiveinsulation and weather proo seal.

Automatic ShutdownA built-in shutdown sensor eliminates theneed or a dump tank. This capability isactivated at high temperatures when thereis less heat required than produced.

Indirect

Storage Tank

Baxi indirect storage tadesigned to be integratwith the solar heating sare supplied standard wdual serpentine coils.

Baxi tanks are availableseveral sizes, ranging rgallons (180L) to 211 g(800L) in capacity.

Baxi Field Test Results

Green and FreeEnergy

In a feld test conducted nearCooperstown, N.Y., a two-panelBaxi Solar Water Heating Systemwas selected to heat a newenergy efcient 4,000-square-ootpassive solar home locatednear Cooperstown, New York.

The Baxi Luna 3 Comortmodulating combination heatingand domestic hot water boilerwas also integrated with thesystem to provide supplementaryheat. The frst wallhung boilerbuilt with solar in mind, the boileraccepts pre-heated water romthe solar storage tank, brings itquickly and economically up todemand, and then shuts o.

The homeowners o this solarfeld test report they used just115 gallons o propane romJune through December. Duringthat period, neighbors with asimilar sized home (built fveyears previously) say they usedalmost fve times more uel just to heat their home.
