Biasi Boilers

The article is an overview of the popular Italian manufacturer of gas boilers for domestic use, Biasi. Biasi boilers are compact and wall-hung units that are designed as the combination and system gas boilers for use in direct home and residential water heating or space and indirect water heating. Biasi produces several tankless models, grouped in four categories, all with the warranty ranging from 2 to 5 years.

Biasi Models and Features

Inovia and Advance Plus

Biasi Inovia BoilersInovia and Advance Plus series are the groups of the high efficient condensing combi and system boilers from Biasi manufacturer.

There are three combination models with the maximum power of 35KW for both series, and one systems boiler with 25kW in Inovia series, while Advance Plus offers three systems boilers ranging from 16kW to 30kW.

Both groups of gas boilers utilize the advanced features such as the full pre-mix modulating burner that is able to produce hot water with the efficiency of close to 89% and maximum water flow of 15.6 L/min. Both Inovia and Advance Plus group of gas boilers include the quad technology that allows boilers safely to operate even if the unit shows the faulty code.

The intelligent technology comes with the several benefits for the users; programming, easy control and monitoring, reliable operation and self-diagnostics for easy troubleshooting. All the above features provide better comfort for the user, clean gas burning and low NOx emission, which makes the boilers environment-friendly.

For additional benefits, Biasi boilers from Inovia series, as the most advanced boilers from this manufacturer, can be connected to the hot water cylinders, solar thermal system, radiator and underfloor heating system and controlled independently with the built-in programmable thermostat.

Biasi Advance Plus
When comparing the models; NOx emission is lower on the Advance Plus models.

The Advance Plus combi and system boilers come with the digital self-diagnostic and historical fault diagnostic, while Inovia boilers have a built-in self diagnostic LED indicators, 7-day time control and the timed pre heat function that preheats domestic hot water.

Biasi Riva Plus Other groups of Biasi boilers are Riva Plus and Riva Advance, also designed as the combi and system gas boilers, but with the shorter warranty of 2 years.

The design of Riva Plus is simpler than the above models, which makes it less expensive and more affordable. The main features are the stainless steel DHW heat exchanger, new recuperator heat exchanger made of aluminum and specially designed to extract even more heat from the flue gases, modulating fan and the burner for optimized gas combustion.

The control panel of the above Biasi boilers consists of easy-to-use control knobs for adjusting the temperature of both DHW and central heating temperature, temperature and pressure gauge, self-diagnostic LED light indicators, and the built-in 24-hour digital programmer for easy control. Riva Plus models are found in two sizes; 24 and 28kW, with the efficiency of 88% and maximum water flow of 11.6 L/min, recommended for two bathrooms. Self diagnostic is also part of the boilers, so as the option to use the propane LPG gas.

Riva Advance group of gas boilers also has one model with the power output of 24kW that is designed as the combi and system type, and more powerful 32kW unit that operates only as the combination boiler. This model is able to provide even more hot water of 14.2 L/min.

The efficiency is close to 90% while the emission of the NOx gases is lower than the Riva Plus models (37 vs. 95 ppm). Another great advantage is that the Advance group can be combined with the solar thermal system and the hot water cylinders therefore taking the advantage of the free solar energy. The control panel is the same as the one found on Riva Plus but with the 7-day programmer. Other differences include the Giannoni pre-mix stainless steel condensing heat exchanger, high performance DHW HE also made of SS, and electronic controls for the optimized gas/air ration.

The above features are from the combination boilers which are used for both space and DHW heating all packed in one compact unit, while the system models do not utilize the DHW heat exchanger and its hydraulic components but are combined with the unvented hot water cylinders.
