KON B

Refined wall-mounted condensing boiler, KON B, offers a new form of comfort. In its DNA it has the KON technological platform, integrated with the 60-litre superfast “storage tank” in AISI 316 L stainless steel. It is designed to guarantee comfortable showers with supply at a constant temperature and for a long time, without being affected by “variations” caused from the insertion of other users. With the accumulation at 70°C , 50 liters of high temperature water are available, which can be mixed with cold water, which supply over 195 liters in the first 10 minutes with Δt 25K .

After the boiler has been discharged, dispensing continues to remain at a constant 45°C over time. The user can obviously choose the delivery temperature using the control on the panel. The preparation of the kettle takes about 10 minutes from cold and the refilling, starting from 45°C, in less than 6 minutes. The sanitary priority system is based on the tried and tested complex with electric 3-way valve. A highly effi cient combination of hardware and software, which allows operation in high and low temperatures with differentiated priorities, combined with the excellent premix exchanger-condenser group, provides speed to bring the heating system up to speed and very high savings. Particular attention has also been paid to the reduction of noise emissions as well as to the insulation of the boiler to avoid unnecessary dispersions. KON B, the protagonist by Unical.

Savings with the exclusive primary exchanger

in Al/Si/Mg KON B employs, like all ”Scuola Unical” products, an original primary exchanger. It is made of a special Aluminium/Silicon/Magnesium alloy which ensures efficiency and resistance, so much so that it is guaranteed by Unical for 5 years. Thanks to the internal heat exchange configuration, efficiencies of up to 108.2% (ex dir. 92/42) can be reached in the condensing regime, which means great economic savings and very low environmental impact for the user, for better exploitation of the fuel.

Wide power modulation

This feature makes it possible to determine, thanks to the thermostat and on-board sensors, the right instantaneous power required, reducing the on-off phenomena responsible for high consumption. The homologation in the power band (Range Rated) gives the opportunity to fix the power supplied, adapting it to the needs of the system. The "ANTIFAST" system further reduces the on and off cycles, optimizing yields and costs. It is an electronic ignition retarder which intervenes after the boiler has been switched off due to the temperature being reached.

Advantages:

  • Quick set-up when turned on.
  • Reduction of on-off cycles with reduction of consumption and wear of components.
Modulating premix burner

With electro-pneumatic control and constant combustion ratio, the “Flat” type burner ensures long life thanks to the low thermal and mechanical stresses and the physical inalterability of the FeCrAlloy fiber fabric, as well as an ideal propagation of heat by radiation thanks to its structure capable of developing a particularly soft and luminous flame. The "Quick release" release of both the upper plate and the bottom of the exchanger allows the complete removal of the combustion system together with the widely tested and updated complex of electronics and premixing system. The pneumatic gas solenoid valve and the fan, both modulating, are distinguished by their limited overall dimensions.

Advantages:
  • compactness and reduced acoustic emission
  • wide modulation range 1:6.3
  • absolute operating safety due to the absence of turbulence
  • The valve is designed to compensate for gas pressure fluctuations present in networks as well as stabilize the supply pressure independently of the suction pressure generated by the premix fan.
  • Easily adjustable, it ensures an accurate air/gas combustion mixture (Low NOx) to guarantee high CO2 levels and favor condensation.
High efficiency modulating circulator

with deaerator It represents the state of the art in the high effi ciency standard. In line with the 2015 ErP directive, with less than 1W consumption in stand-by and only 45W in maximum operation, thanks to the wide modulation capacity, based on the request of the room thermostat and the temperatures detected by the sensors placed in delivery/return, automatically doses the boiler power to the system requirements. When preparing the domestic hot water boiler, it contributes positively to speeding up the times and reducing the on/off of the burner. Particularly silent and compact, it integrates perfectly with the safety valve, the adjustable by-pass and the drain cock.

Inside the kettle

  • Storage capacity of 60 litres, fully flanged, easy to inspect and insulated in self-extinguishing polystyrene.
  • AISI 316L stainless steel
  • Arrangement of the water-water coil in 2 extractable concentric spirals arranged in the lower part of the boiler. In this way, maximum heat exchange is obtained with the incoming cold water, which is injected by a special flow breaker which reduces the turbulence in the upper area where the hot water is drawn
  • Length of the primary coil: 13 meters Exchange surface: 0.85 m2 Charging time from 12 to 74°C: about 10 minutes
  • Emptying tap
  • Water heating energy efficiency ηwh equal to 68.1% according to dir. Erp, which makes it a boiler capable of supporting demanding and intensive withdrawals, even over time. The magnesium anode protects the boiler from parasitic currents and confirms the 5-year guarantee.
  • Healthy water thanks to anti-legionella: the very useful automatic electronic program provides, every 186 hours, a high temperature cycle (70°) which "sterilizes" the boiler, preventing any bacterial proliferation.

    Warranty detailsWarranty details

    Pursuant to art. 63 of the Consumer Code, the risk of loss and damage to the goods, for reasons not attributable to the seller, is transferred to the consumer when the latter, or a third party designated by him and other than the carrier, physically comes into possession of goods. However, the risk is transferred to the consumer as soon as the goods are delivered to the carrier. The Customer who at the time of purchase has decided to make use of the extra insurance service for the transport of the purchased goods, in the event that he finds anomalies at the time of delivery (packaging damaged or otherwise altered in the closing seals, damaged product or scratched, missing one or more packages ordered), must accept the product by writing on the document provided by the carrier: "WE ACCEPT WITH RESERVE" + description of the anomaly found. In fact, to enforce the insurance coverage it is not sufficient to note "ACCEPTED WITH RESERVE" or "ACCEPTED WITH SUBJECT TO INSPECTION", BUT the reason for the reservation must be explained in detail. If the package or the product should show visible damage, scratches or any other type of anomaly and the courier should refuse to affix a specific reserve, the goods must be refused and the incident reported immediately (and in any case in a timely manner) to the Customer Service of Decidiprice srl. In any case, without prejudice to the seller's obligations in terms of legal guarantee pursuant to articles 128 et seq. of the Consumer Code, Decidiprezzo srl will not be held responsible for any anomalies found in the state of the product, after delivery, if the Customer, in the presence of an anomaly, has accepted the package without making a specific reservation (in the corrected above). Any damage or anomalies must be reported to Customer Service by email to postvendita@climaconvenienza.it. The request must be forwarded no later than 8 calendar days from receipt of the goods. Any notification beyond the aforementioned terms will not be taken into consideration.
