RinNova adaptive

The RinNova Adaptive condensing boiler , unlike traditional boilers, allows energy to be recovered by condensing the water vapor contained in the exhaust fumes; that is, for the same heat produced, it consumes less gas and furthermore the exhaust fumes contain fewer substances harmful to the environment. The materials that compose it and the regulation systems with which it is equipped offer safety, high comfort and energy saving, so that you can fully appreciate the advantages of independent heating.

RinNova Adaptive is the new BIASI model of wall-mounted condensing boiler .

It offers excellent performance and high yields that last over time, thanks to the innovative heat exchanger. Simple to use thanks to the digital control panel, with a display designed to communicate with the user easily and conveniently.

Technical features

  • Boiler with single circuit stainless steel primary exchanger, free of joints and/or welding, which maintains high efficiency even on older systems
  • New combustion system with patented gas-adaptive technology (Advanced Adaptive Gas Combustion Control – A²GC²) The electronics continuously analyzes the combustion (CO2) through the flame signal and intervenes by acting on the gas valve and the fan, to allow correct combustion in all conditions of use. The electronics allow you to easily adapt the boiler to the various types of gas without having to intervene with a mechanical transformation kit
  • Instant production of domestic hot water with dedicated plate exchanger
  • Domestic hot water pre-heating function: faster delivery of domestic hot water
  • User interface with display and multifunction keys for adjusting and setting parameters
  • Easily inspected standard by-pass
  • Chimney Protection System: electronic management of fume overtemperatures, guaranteeing maximum protection of the chimney
  • Ducting on flue pipes: particularly suitable for operation in flue pipes that require ducting with high pressure losses
  • Minimum polluting emissions (class VI - EN 15502-1)
  • Sliding temperature operation via optional external probe
  • Low consumption modulating heating circulator (ErP Ready - Class A)
  • Digital flame control with three re-ignition attempts in case of operation block due to lack of flame detection (methane configuration)
  • Removable three-piece casing for easier maintenance or inspection
  • For SV versions: possibility of setting the maximum power that can be delivered to the external boiler

Gas Adaptive Technology

Less consumption, more efficiency, less emissions

The innovative Adaptive Gas technology, which all models in the Rinnova line are equipped with, allows the boilers to be completely autonomously adapted to the different types and qualities of gas. The electrode, in addition to detecting the flame, also detects the characteristics of the gas and automatically adapts the combustion parameters to maintain the maximum level of efficiency, with a consequent reduction in consumption and emissions compared to traditional control systems. The Adaptive gas system makes the boiler ready to operate with any type of gas without transformations.

  • Automatic gas adjustment
  • Adaptation to changes in gas quality
  • Clean combustion
  • Only model suitable for methane and LPG which allows you to optimize the warehouse
  • In traditional boilers, the combustion values ​​are detected and regulated only during the maintenance phase. Furthermore, the composition of the mains gases is not always constant and can create inefficiencies in operation on boilers without combustion control devices, compromising reliability and savings. and the quality of emissions.
  • Thanks to the Gas-Adaptive system, the new condensing boilers electronically control combustion, managing the gas and air supply in the best possible way at all times, automatically adapting the CO2.

A "Plastic-FREE" production

For a more sustainable environment

A fundamental element that guided the entire design phase of the new Rinnova Adaptive boiler is the strong attention to the circular economy. For this reason we have used components with a higher recyclability rate, eliminating the use of plastic as much as possible. The plastic group, for example, has been replaced with the brass group, a completely recyclable material. The boiler protection shells were made of cardboard and no longer polystyrene. Furthermore, the front is no longer made of plastic but of pressed steel.


Climatic regulation (with optional external probe) and room regulation (remote) to allow correct management of the water temperature in order to reduce consumption and consequently reduce emissions.
By using climate regulation, the regulation efficiency also increases, giving greater value to the home.

High circulation single-spiral primary exchanger

Biasi introduces the Round exchanger in 2017. Its great reliability has been demonstrated, making it part of the Rinnova Adaptive range. Round is a compact monothermal heat exchanger based on a stainless steel coil with an oval section.

The heat exchanger consists of a combustion chamber, condensation area 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/outlet connections, provides the following benefits:

  • The accumulation of dirt and debris is avoided
  • The water flow rate is uniformly distributed and guarantees a homogeneous heat exchange
  • The water flow rate is constant for a longer product life
  • Reduction of pressure drops with optimized circuit
  • The ease of cleaning and the robustness of this exchanger are one of the main strong points of the product given that it can be used on new systems but also on old systems in the event of renovations.

Round integrates the round flow function in which the water produces a centrifugal cleaning effect on the internal walls of the single coil. The absence of parallel circuits guarantees an easy "washing" operation of the exchanger and the elimination of any air present in the system circuit.
