Condensing technology -

the most advanced way to heat

Condensing technology maximizesfuel utilization and reduces yourheating bills. By capturing the portionof latent heat, which in conventionalheating boilers is lost through thechimney, condensing boilers, like theVitocrossal 300, use as much as98% of the original energy input toheat your building.

Environmentally-friendly

Apart from economic considerationscondensing technology also minimizesthe environmental impact of theheating system. Better fuel utilizationmeans lower fuel consumption andconsequently lower emissions.

Due to their high efficiency and lowenergy consumption, condensingboilers, like the Vitocrossal 300, cancontribute to green buildingcertification, such as the Leadershipin Energy and Environmental Design(LEED) program.

The right choice for new construction

or renovation

Condensing boilers can be used in avariety of temperature applications inboth new construction or retrofits.

A condensing boiler, however,provides the most benefit inapplications with low operatingtemperatures, such as radiant floorheating, snowmelting systems,oversized radiators and fan coils. Thelow boiler supply and returntemperatures of these systemsfacilitate the condensing of the fluegases and extraction of additional,latent heat, resulting in peakefficiencies and maximum energysavings.

In systems with medium to highoperating temperatures, condensingboilers combined with outdoor resetcontrol technology, are still able toachieve high efficiencies, especially inthe shoulder season. The combinationof a condensing and non-condensingboiler is often used in multi-temperature systems to satisfy thevarious temperature requirementsmost effectively.

Today, the use of condensingtechnology is almost a given,especially in new construction whenthe temperature requirements of thesystem and can be matched perfectlywith the boiler.

Reliable and economical

In order to maximize the benefits ofcondensing technology, look for thefollowing features in your condensingboiler:

� The use of reliable and corrosion-resistantmaterials such as stainless steel

� Highly effective heat exchanger surfaces forlow flue gas temperatures and highcondensation rates

� Matching, innovative burner technology

� Low after-sales costs, e.g. for systemmonitoring, maintenance and repair

� Total system solutions, which only a largemanufacturer with extensive experience, anda wide complementary product range, suchas Viessmann, can offer

Stainless steel flue gas collector withcondensate drain

The Vitocrossal 300 is anexceptionally efficient andenvironmentally-friendly gas-firedcondensing boiler for semi-commercialor commercial heating applications -from large custom homes toapartment buildings, schools andother public and commercial spaces.Superior efficiency, highest-qualitymaterials and proven Viessmanncondensing technology translate intoincreased savings in fuel andmaintenance costs.

Built to last

The Vitocrossal 300 is constructedusing only the highest qualitymaterials. The Inox-Crossal verticalheat exchanger surface is made ofhigh-grade SA 240-316 Ti stainlesssteel - ideal for condensingapplications.Corrosive condensate simply drainsdownward off the smooth surfaces,effectively self-cleaning the heatexchanger and extending theoperational life of the boiler, whilereducing maintenance costs.
