General Features

• Edil HE
  
  
  
  Edilia HE is the new Savio range of built-in 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 versions for heating and domestic hot water production, Edilia HE offers a full range of power outputs, 20 and 30 kW combi models, in the same extremely compact dimensions (1200 x 600 x 240 mm). Edilia HE's strength lies in its innovative heat exchanger, designed to provide long-lasting high efficiency and a digital control panel, designed for easy and convenient user interaction.
  
  Like the entire Savio condensing range, Edilia HE allows you to obtain maximum savings from climate control, based on the system in which the boiler is installed.

  Savio introduces its new stainless steel heat exchanger for condensing boilers: Round. Round is a compact monothermal heat exchanger based on a stainless steel coil with an oval cross-section. The heat exchanger consists of a combustion chamber, a condensation zone, and an insulated metal disc protected with silicone ceramic fiber that separates the two areas. Using a single stainless steel strip to produce the coil, including inlet and outlet connections, offers the following advantages:
  
  
  It prevents the accumulation of dirt and debris
  The water flow is uniformly distributed and guarantees a homogeneous heat exchange
  The water flow is constant for a longer product life
  Reduction of pressure drops with optimised circuit.
  
  The ease of cleaning and robustness of this exchanger are among the product's main strengths, as it can be used on both new and existing systems during renovations. Round integrates the round flow function, in which water produces a centrifugal effect that cleans the internal walls of the single coil. The absence of parallel circuits ensures easy "washing" of the exchanger and the elimination of any air present in the system circuit.
