Main features


The new range of wall-mounted condensing boilers: excellent performance thanks to the new heat exchanger

Evodens HE is the new SAVIO range of wall-mounted condensing boilers: excellent performance thanks to the new heat exchanger and ease of use thanks to the digital control panel with large display. Available in the versions for heating and domestic hot water production and for heating onlyÿEvodens HEÿpresents a complete range of powers, 25 and 35 kW combi models and 25 and 35 SV models, in the same extremely compact dimensions (700 x 400 x 290 mm).ÿ

Evodens HEÿhas its strength in the innovative heat exchanger designed to provide high yields that last over time. Digital control panel, designed to communicate with the user in an easy and comfortable way.

Like the entire SAVIO condensing range, Evodens HE allows you to derive maximum savings from climate thermoregulation, based on the system in which the boiler is installed.


High yields (compliant with yield directive 92/42ÿEEC and Legislative Decree 311/06)

Sanitary comfort (EN 13203)

Stainless steel primary condensing exchanger with aluminum coatings to offer maximum corrosion resistance

Total premix burner, made of stainless steel (NOx Class 5)

Modulation 1:10 Methane also LPG

Sanitary plate exchanger in stainless steel

7 liter expansion tanks

High efficiency PWM pump with low energy consumption and variable speed

Maximum power adjustable based on the system

IPX5D protection ratings

Installability in partially protected locations

Integration with Savio solar systems, using a solar kit

Innovative digital control panel

Digital pressure reading

Predisposition for external probe remote control

Possibility of managing a zone valve using remote control in the case of multi-zone systems.

High circulation primary single-spiral exchanger Savi produces the new Steelcoil exchanger composed of a stainless steel spiral enclosed in an aluminum shell. Thanks to the high exchange surface of the coil, greater thermal efficiency is guaranteed with less charge loss and greater ease of cleaning. The ease of cleaning and the robustness of this exchanger are one of the main strengths of the product, which can be used on new systems but also on old systems in cases of renovation. Steelcoil integrates the round flow function in which the water produces a centrifuge effect to clean the internal walls of the coil. Does the absence of parallel circuits guarantee an easy washing operation? of the exchanger and the elimination of any air present in the system circuit.

By connecting the external probe and the remote control (optional) directly to the boiler you can take advantage of climate regulation. EVODENS HE will adapt the system water temperature to the external climatic conditions, guaranteeing the achievement of the desired room temperature without waste and optimizing consumption. By using climate regulation, the regulation efficiency also increases, giving greater value to your home.

Ecodesign Directive: new condensing boilers from 2015

After very long negotiations, the Ecodesign regulation was approved, which introduces a new energy labeling on the minimum efficiency standards for boilers. In particular, an energy classification from A+ to G is provided for space heating appliances and from A to G for domestic hot water production appliances. "Hence the obligation to install only condensing boilers, heat generators capable of recovering a large part of the latent heat contained in the fumes which, otherwise, would be lost in the chimney" as happens in traditional boilers. The recovered heat is transferred to the heating system, allowing to reach an efficiency of 106% compared to 92% of the traditional boiler and 84/85% of an old traditional generator. The installation obligation concerns boiler manufacturers who will no longer be able to place those 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 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 oa open room? to be installed... when it is not possible to replace an old boiler with a condensing boiler... due to problems related to the collective flue... of some multi-family buildings.

Products for water and space heating represent approximately 30% of internal energy consumption in Europe.

Designing eco-friendly products and promoting high-performance technologies to end users in 2020 will determine:

An annual energy saving equivalent to 56 million tonnes of oil, quantifiable as the savings obtained if the water and environmental heating systems of two nations as large as Italy were deactivated.

As of 26 September 2015, ErP regulation and energy labeling will be applied in Europe to water and space heating products (boilers, heat pumps, micro-CHP devices, water heaters, and hot water storage tanks) û.

How to read energy labels

There are different labels, based on the type and functions of the product (room water heating only of both, and in this case the label must show both classifications).

In addition to the energy class, the label provides other information that could be useful for understanding which product has the lowest environmental impact (for example, power and consumption in different climate zones, noise, etc.).

It is possible to increase the energy efficiency of hot water production and space heating by connecting multiple products and accessories to one system. In this case it is necessary to prepare a system label in addition to that relating to the individual product
