The large Hoval BioLytWood pellet fired boiler with50 and 70 kW output for apartmentblocks and other large buildings

Rising oil and gas prices are prompting more and moreproperty investors to look for more economical solutionsfor new buildings and also for refurbishments. One ofthese fuel alternatives is wood. Wood is a locally available,CO 2 -neutral and sustainable energy carrier whichprovides a first class price performance ratio, securedsupply for the future and especially an excellent ecologicalimpact rating. In addition, modern technology fromHoval allows us to enjoy these advantages without anyloss in comfort, even for apartment blocks, public andindustrial or commercially used buildings.The solution: high-performance wood pellet boilersfrom the BioLyt range.

Built-in efficiency.The Hoval BioLyt switches itself on and off automatically and adjusts theheating output to meet the current demand perfectly. The burner can bemodulated between 30% and 100% performance. Operation, functionalcontrol and fuel dosage are all managed efficiently by the intelligentHoval TopTronic ® T controller. This means that the Hoval BioLyt achievesan efficiency rating of more than 90% - a first-rate combination of maximisedefficiency and minimised environmental impact.Continuous performance thanks to self-cleaning heating surfaces.The heating surfaces provide the means for transferring heat energy tothe boiler water. If they become soiled this impairs the efficiency of theheat transfer which leads to higher fuel consumption and emissions. TheHoval BioLyt contains patented self-cleaning heating surfaces togetherwith a motorised heating surface cleaning system. This ensures that thesurfaces remain clean and guarantees a continuously high performancerating – while reducing maintenance requirements.Ash disposal and cleaning – with a minimum of effort.‘Hoval easy’ means: We want to make our products as simple to operateand maintain as possible – including our solid fuel appliances. Customersbenefit from solutions which have been thought through in detail – suchas the BioLyt wood pellet boiler’s ash extraction system. Most of the ashresulting from the combustion process is transported automatically to theash collector. The collector itself must be emptied a few times per heatingseason, depending of course on how high the heating demand is. Inaddition, the combustion chamber must be cleaned between one andthree times per season using a scraper and vacuum cleaner. This canbe done by the plant owner or a person appointed by him to look afterit. Depending on the operating conditions a general cleaning of the boilerand flue gas system must be carried out once or twice per year.Technical dataHoval BioLyt Type 50 70nominal heating capacity kW 14 – 49 20 – 69boiler efficiency at nominal performance rate % 92.9 94.5pellets container capacity litres 240 240boiler weight kg 390 520dimensions W/H/D mm 740/ 1945/ 1870 800/ 2025/ 1870subject to modifications

The large Hoval BioLyt:An investment that soon pays for itself.Low heating costs, ease of operation and an outstandingenvironmental impact rating constitute excellent reasonsfor implementing the large Hoval BioLyt in new buildingprojects as well as refurbishment of older buildings suchas apartment blocks, public and industrial or commerciallyused buildings. Modern pellet firing technologyand a fully automated fuel supply system make thisstate-of-the-art pellet fired boiler as easy and efficientto operate and maintain as a modern oil or gas heatingsystem.Wood: the environmentally friendly energy supply.One of the most environmentally friendly sources of heatingenergy grows practically next door – in the form of trees!Wood used for heating purposes is completely CO 2 neutral,because when it is burned only that amount of ‘greenhouseeffect’gases are released which the trees involved extractedfrom the atmosphere during their growth period. The CO 2tax which is to be introduced in Switzerland will not be leviedon wood fuel. And: Heating with wood is significantly cheaperthan using oil or gas as well as providing for a sustainablefuture.Pellets – concentrated energy packets.The fuel used in the Hoval BioLyt consists of wood pelletswhich are made from 100% untreated, natural wood. Theraw material for their manufacture is obtained from wasteproducts such as sawdust and shavings from the woodprocessing industry. The raw material is pressed into smallcylinders using high pressure and without the need for binders.A year’s supply can be stored economically in a pellets roomor in an underground tank. The pellets are delivered by thesupplier in tankers, just as heating oil is.Simple and economical operation.As far as comfort and ease of operation are concerned, theHoval BioLyt is comparable with a modern oil or gas heatingsystem. The fuel supply is fully automated and the smallamount of ash which remains is transported to an ash collector– also automatically. The collector can easily be emptied.In addition, simple cleaning operations must be carried outregularly.Sunlight and wood: The perfect combination!For a completely CO 2 neutral and especially economicaldomestic heating system you can combine a BioLyt pelletfired boiler with a Hoval solar plant for water heating or forancillary room heating. The digital Hoval TopTronic ® Tcontroller ensures that the plant components are perfectlyharmonised with each other – fully automatically.This apartment block in Davos is heatedusing a BioLyt pellet fired boiler.
