Artica Plus is the new BIASI range of outdoor wall-mounted condensing boilers : excellent performance thanks to the new heat exchanger and ease of use thanks to the digital control panel with display. In the version for heating and domestic hot water production, Artica Plus is available in two powers, 20 and 30 kW, in the same extremely compact dimensions (946 x 509 x 287 mm). Artica Plus has its strong point in the innovative heat exchanger designed to provide high yields that last over time. Digital control panel, designed to communicate with the user easily and conveniently thanks to the remote control plus supplied as standard. Like the entire BIASI condensing range, Artica Plus allows you to derive maximum savings from climate thermoregulation, based on the system in which the boiler is installed.

High circulation single-spiral primary exchanger

Biasi introduces to the market the 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 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. By using a single stainless steel strip to produce the coil, including inlet/outlet connections, the following advantages are achieved:
  • 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.

Control panel
  • Summer/winter/off selector
  • Heating temperature regulator
  • Domestic hot water temperature regulator
  • Analog pressure reading
  • DHW temperature and heating displayed
  • Display of fault diagnostics, lockout status and fault history
  • Recommended filling display and filling guide
  • Display of annual maintenance deadline

The display operates in the following ways:

1. INFO. Info mode displays the following information:

- External temperature (in case of external probe connected)
- K value (in case of external probe connected)
- Domestic hot water/heating temperatures chosen by the user
- Smoke temperatures

2. PROGRAMMING. The programming mode allows you to modify the boiler parameters.

- In chimney sweep mode it is possible to test the boiler and make adjustments to the gas valve.


By connecting the external probe (standard) and the plus remote control (standard) directly to the boiler you can take advantage of climate regulation. Artica Plus will adapt the system water temperature to external climatic conditions, ensuring the desired room temperature is reached without waste and optimizing consumption. By using climate regulation, the regulation efficiency also increases, giving greater value to your home.
