Main features
ALDENS
ALDENS the new SAVIO range of condensing wall mounted boilers: excellent performance thanks to the aluminum heat exchanger and ease of use thanks to the control panel with knobs and display. Available in the combi version which combines the heating function and the production of domestic hot water. ALDENS presents a complete range of powers, 24 and 35 kW combi in the same extremely compact dimensions (700 x 420 x 345 mm). ALDENS has the strong point in the innovative primary heat exchanger in Al/Si/Mg with low water content designed to provide high yields that last over time. The digital display communicates the boiler operating parameters to the user in an easy and convenient way. Like the entire condensing range, SAVIO ALDENS allows you to make the most of savings from climatic thermoregulation, based on the system in which the boiler is installed.
Main features:
Outstanding fine 1:8 modulation ratio
Efficiency>107% (ex dir. CE 92/42)
Primary heat exchanger in ultra-flat Al/Si/Mg
Electronics with HWS or Hot Water Speed function?
Low NOx (class 5 according to EN 297 and EN 483) thanks to the modulating premix burner
Production of fine hot water 13.3 l/min t 25 with special 12-plate (mod. 24 kW) and 16-plate (mod. 35 kW) exchanger in stainless steel
Maintenance or Pit Stop?
simple and intuitive control panel
High efficiency modulating circulator (in line with ErP Dir. 2015)
Sanitary exchanger
Sanitary comfort ensured by the suitably sized plate exchanger to guarantee the best performance in terms of domestic hot water, reducing the waiting time and guaranteeing temperature stability.
Modulating circulator with deaerator
It represents the state of the art in the standard of high efficiency. In line with the ErP directive of 2015, with less than 1 W of consumption in stand-by and only 45 W 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 on the delivery/return automatically doses the boiler power to the needs of the system. Particularly silent and compact, it integrates with the safety valve, the by-pass and the drain cock.
Exclusive Ai/Si/Mg heat exchanger
It is made in a special Aluminum/Silicon/Magnesium alloy which ensures its efficiency and resistance over time. Thanks to the configuration of internal heat exchangers, efficiencies higher than 107% are achieved in the condensing regime, which means great economic savings and very low environmental impact for the user. The 35 kW version suitably increased.
Plus
Manage 2 zones with 2 thermostats:ÿALDENS versatile. Ideal for all systems, thanks to the electronics that allow you to manage 2 different temperature heating zones (high for radiators and fan-coils, low for radiant panel systems) by controlling them with dedicated modulating and on-off thermostats.ÿ
Anti-overheating post-circulation:ÿFor 15 seconds, it maintains the thermal balance between delivery and return, even after intense DHW withdrawals, while in heating, with a duration of 5 minutes, it allows all residual thermal inertia to be disposed of.ÿ
Sliding temperature operations:ÿFor maximum running economy.ÿ
Antifreeze protection:ÿIt intervenes at 5°C and is activated in both domestic hot water and heating, bringing the temperature in the boiler to 15°C. The risk is avoided that ALDENS may freeze if low temperatures persist in the room where it is installed. If there is a lack of gas, the block signal will appear on the display.ÿ
Pump anti-blocking: blocking of the pump following long stops is avoided thanks to an automatic 5-second pulse that the electronics sends to the motor every 24 hours of stop
The multifunction LCD display, with timed backlighting, allows:
Reading of the heating and sanitary temperatures
Display of lockout due to lack of flame
Error code display
Malfunction signaling
Operating/stand-by status
Burner operating status
Diagnostics with signaling of 11 anomalies
Ecodesign directive: from 2015 on new condensing boilers
In fact, after very long negotiations, the ÿEcodesign regulationÿ was approved, which introduces a new energy labeling on minimum efficiency standards for boilers.ÿIn particular, an energy classification from A+ to G is envisaged for space heating appliances and from A to G for appliances for the production of domestic hot water. ÿHence the obligation to installÿonly condensing boilers, heat generators capable of recovering a large part of the latent heat contained in the fumes which, otherwise, would be dispersed in the chimneyÿas occurs in traditional boilers. The recovered heat is transferred to the heating system, making it possible to achieve a yield of 106% with 92% of the traditional boiler and 84/85% of an oldÿÿtraditional generator.ÿThe installation obligation concerns manufacturers of boilers which will no longer be able to place on the market non-condensing starting from 26 September 2015. This means that starting from this date, anyone who wants to install a boiler in their own home will have to install only condensing models. Only one particular type of non-condensing boiler will continue to be produced which is technically called open room? to be installedÿ when it is not possible to replace an old boiler with a condensing boilerÿdue to problems related to the collective flueÿof some multi-family buildings.
Products for heating water and the environment represent around 30% of the world's energy consumption in Europe.ÿ
Designing eco-friendly products and promoting high performance technologies to end users in 2020 will lead to:
An annual energy saving equivalent to 56 million tons of oil, quantifiable to the savings obtained if the water and environmental heating systems of two large nations like Italy were deactivated.
As of 26 September 2015, the ErP regulation and ÿenergy labelingÿwill be applied in Europe to water and space heating products (boilers, heat pumps, micro-CHP devices, water heaters, and hot water storage tanks) u.
How to read energy labels
There are different labels, based on the type and function of the product (only room water heating of both, and in this case the label must bear both classifications).
In addition to the energy class, the label provides other information that could be useful for understanding which product has the least environmental impact (for example power and consumption in different climatic zones, noise levels, etc.).
It is possible to increase the energy efficiency of hot water production and space heating by connecting several products and accessories in one system. In this case it is necessary to prepare a system label in addition to that relating to the single product
