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
Inovia 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.
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.
Riva
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.
