... point by pointAluminium heartApplying the same technology used inthe motorcar industry, the ALKON’s 50motor is a cast aluminium/silicon andmagnesium heat exchanger/condenser.Its major features are the lightweightand compact design: weighing only10 kg and measuring 12 cm in depth,47 cm high and 43 cm wide. The verysevere final tests (according tothe Standard EN 303-1, with a pressureof 26 bar) brilliantly passed, testifythe high quality of this casting.The technology (Unical patent),already experimented on the rangeof high and average output MODULEXboilers, has permitted the constructionof a compact heat exchanger which,as well as favouring an elevated heattransfer, also consents self-cleaningof the flue side.Thus, the following benefitsare guaranteed:• Long lasting performance, thanksto the absence of lime scale.• Extremely easy servicingMoreover, thanks to the 100% wetsurfaces in the heat exchanger,a maximum lifespan and reliabilityis ensured, thanks to the optimumcirculation which neveroverburdens it.Blue flameThe combustion system is sited ina special sealed box, placed abovethe heat exchanger, composedby a modulating fan, gas valve, gas/airmixer, ignition device, flame controland a special ‘metal fibre” burner whichproduces the so-called “blue flame”pre-mixed combustion, with a CO 2emission equal to 9% at minimumand maximum output.Silent performanceThanks to the pre-mixed modulatingfan’s low operating pressure, capableof developing a soft flame, the ALKONboiler ensures quiet operation.Low NOx microflameThe microflames which develop internallyundergo a very quick cooling downprocess with a subsequent reductionof the volumetric thermal load.Class 5 Low NOxIn the ALKON boiler, the particular blueflame pre-mixed combustion,with an equivalent flame temperature,transmits greater energy than thatobtained with traditional combustion.Thanks to the practically total oxidizationof the molecules of natural gas, the verylow polluting emissions producedpromote the ALKON boiler intothe selective Class 5 Low NOx category(EN 483). Moreover, the absenceof turbulences ensures absolutesafe operation.Optimum long flue lengthsThe pre-mixed combustion, thanks tothe available manometric head,guarantees flue outlet systems upto 30metres long with a diameter of 80 mm.Efficiency (%)110109108106104102100989694High resistance and long lifeThe physical unalterability of theburner’s metal fibre construction limitsthe mechanical and thermal stresses,ensuring long life. Servicing is facilitatedthanks to the reduced use ofcomponents and ease of access.Exceptional modulation ratioThe prerogative for obtaining a highseasonal efficiency is to be ableto dispose of a “flexible” boiler.To be able to modulate down toan output of only 8,8 kW means thatthe boiler is able to adjust itself to therequired output to meetthe system’s minimum loads, withoutmaking the burner fire/turn offexcessively, dispersing energy uselessly.This same flexibility guarantees areserve of energy, which is alwaysready to satisfy extreme requirements,such as a great demand of immediateheat output.CasingThe casing is in steel plates, paintedwith epoxy-polyester powders andinternally insulated with reflectingpolyethylene materials 5 mm thick.EFFICIENCY DEPENDING ON THE HEATING LOAD20 25 30 35 40 45 50 55 60 65 70Return temperature (C°)30% part load100% full load

Money saving ...Operating efficiency levelsupto and over 108% !The condensing technology has the primaryscope of drastically reducing latent heat(contained in water vapour), which is lostthrough the flue system, thereby exploitingto the utmost the energy containedin the gas burned and giving the condensingboiler an exceptionally high levelof operating efficiency, impossible to reachwith conventional boilers.The ALKON’s 50 heat exchanger/condenserhas been designed so that the system’sreturning cold water passes throughits terminal part: the contact of the fluegases with this cold surface causestheir transition from the vapour phaseto the liquid phase (condensate),with the subsequent release of heat tothe C.H. system water.This process therefore enables the boilerto recover nearly 1 kW per m 3 of gas burned,which normally, with traditional combustion,would be lost to the environmentwith the flue gasses.Combustion/condensation phenomenonALKONCondensing boilerCONVENTIONALBOILERUSEABLECONDENSING HEAT+12%- 2 % - 1 %100% 112% 110% 109%UNUSEABLECONDENSING HEATFlue sidelossesFlue sidelossesRadiatonlossRadiatonloss- 7 % - 1 %100% 100% 93% 92%FUEL SAVINGThe energy efficiency indicated is the “Net calorific value”Thus the ALKON 50's and ALKON 70'suseful efficiency reaches 109%!Seasonal efficiency, which is stronglyinfluenced by the heating load factor,which is to say, by the variations of usageaccording to the climatic conditionsand the type of heating system, alwaysmaintains itself at very high levels, placingthis boiler at the top of today’s technology.

ALKON’s brainE8, the intelligent heating controllerThe application and connection of the dedicated E8heating controller, permits a decisive qualitative leap inboiler management depending of the applied loads.The E8, as well as becoming the window of dialoguewith the boiler, thanks to its features, permits the completemanagement of the C.H. system, exploiting the maximummodulating output and the maximum obtainablecondensation.Function E8Self-adaptionThrough the elaboration of data transmittedby the room sensor, this function adjuststhe boiler output to the building’scharacteristics, ensuring a constant monitoringof the indoor temperature on the basisof the variation of the outdoor temperature,keeping in consideration the building’s thermalinertia and the contribution of “free” heat(solar radiation, internal heat sources etc).Boiler heating OptimizationThe heating controller, on the basis ofthe timer/heating programme set by the user,once the system’s characteristics have beenevaluated, will activate the function forautomatically bringing forward the start ofheating so as to ensure that the set temperatureis reached at the time requested by the user.Fast set temperatureThis is obtained by calculating the optimumignition start-up time. This calculationcan be carried out taking into considerationthe outdoor temperature or the roomtemperature.Overheating protectionThe boiler’s safety temperature is controlledvia the pumps overrun time in order to getrid of any thermal inertia.Multiple zone controlWith the same heating control you can control2 independent circuits with differentcharacteristics, though having ensuredall the described functions, includingthe deep sliding temperature function.Programme settingThe heating programmes can be set dailyor weekly, with more than one On-Off firingtimes or temperature reductions duringthe arch of the day.Domestichot waterproductionThere are manyprogrammeswhich controlthe domestichot waterproduction.You canchoose from the maximum of comfort tothe maximum fuel saving. In order to permitthe storage cylinder to supply hot water rapidly,the heating controller brings the boiler’stemperature to the maximum set value.AntilegionEvery 20 heating starts-up or once a week, onSaturday at 01:00 hrs, the storage tank is heatedup to 60°C. This function will eliminate anyeventual bacterium which have formed in theDHW.Frost protection modeThe frost protection operation mode preventsthe C.H. heating from freezing by automaticallyswitching heating operation on. In the frostprotection mode, the room temperature for allthe heating circuits is set to 5°C and the storagetank sensor frost protection is activated whenthe temperature drops below 10°C.Optimisation of DHW(loading pump)The DHW loading pump is switched on onlyif the boiler temperature exceeds by 5K thestorage tank temperature. It is deactivated whenthe boiler temperature drops below the storagetank temperature or if the storage tanktemperature is higher than the nominaltemperature.Slope offset (heating slope distance)The boiler temperature that is required for amixed circuit is calculated byadding to the calculatedtemperature setting for theheating circuit temperaturethe heating curve distance.The heating curve distancecompensates for sensortolerances and heat loss upto the mixer.Number of burnerignitionsBurner run hoursMixing valve opening timeBased on the characteristics of theservomotorAnd more:• Management of up to 15 mixed circuitscontrolled by the outdoor sensor (refer toaccessories).• Integration with renewable energy sourcesas for example: solar systems and/or solid fuelboilers.• 0-10 volt signal: the great flexibility of the E8also permits the boiler set point to be controlledby an external control signal. This will enable,having at disposal an even more complex system,to exploit all the heating control’s functions.• Remote controls*: via appropriate software,this function enables the reduction of systemmanagement, remote indication of boiler run,thereby avoiding unnecessary inspection visits.* available in the near future

In order to improve theboiler efficiency it is necessary to maintainthe return temperature as low as possible.Therefore, the ALKON's electronics, incombination with the heating controller, whenthe supplied output decreases, reduces thenumber of revolutions of the pumpand therefore the hourly water flow rate,maintaining the ∆t (temperature difference)practically constant.ALKON 70 is delivered, as standard, withmodulating pump.For ALKON 50 the pump is optional andit is possible to make a choice betweenthe modulating or fixed flow rate pump,thus allowing the highest installationflexibility.ALKON heating system designThe ALKON condensing boiler permitsmany types of solutions for every system.A typical layout can be seen below: theALKON is a rapid generator withLAYOUT OF 2 DIRECT/MIXED AND DHW PRODUCTION HEATING ZONESa low water content, which faithfully followsthe variations of the heating loadwith maximum fuel saving.Provision for a pump will have to be madeon the basis of the circuit’s characteristicsand therefore, interface the boiler’s variousheating loads via the mixing header.ReturnFlowE8heating controllerAdditionalSafety Devices KitMixingheaderDHW CircuitHeating CircuitIts various and very important tasks are:To make independent the connected circuits.To act as “separator” so as to permitthe separation and collection of the sludgeof the system.To vent automatically the air contained inthe circuits.If a DHW storage tank is foreseen, a loadingpump must be fitted.The zones or various C.H. systems,for example in a block of flats with severalapartments, can be controlled by the E8heating controller.Filter
