General Features

DINA is the new line of Biasi wall-mounted condensing boilers, with excellent performance.

It has a stainless steel condensing exchanger with self-cleaning function, has an intuitive digital control panel, is available in 25, 30 and 35 kW power ratings, is certified to operate with up to 20% hydrogen, and has compact dimensions (700x400x268 mm).

Its strong point is the Gas Adaptive technology, which manages to minimize consumption and optimize efficiency : through this system, the boiler automatically detects the characteristics of the gas and adapts to maximize the level of efficiency, thus reducing consumption and emissions.

• H2 Ready / 20% hydrogen
• Carrying out automatic gas combustion analyses
• A single model for METHANE and LPG
• Modulation 1:5
• Total premix burner, made of stainless steel (NOx Class 6)
• 7-liter expansion vessel
• Low energy consumption modulating circulator
• Digital control panel with backlit display
• Provision for modulating thermostat/remote control and external probe
• Can be installed in partially protected environments up to -5°C

Stainless steel primary heat exchanger

The primary heat exchanger consists of:

• A compact, large-section, oval mono spiral, made with self-cleaning technology
• Patented high-efficiency flue gas circuit
• Single combustion chamber that allows for complete cleaning of the exchanger
• High-performance composite flue gas box

The water flow is evenly distributed and ensures homogeneous heat exchange. Pressure drops are reduced thanks to the large cross-section. The ease of cleaning and robustness of this exchanger are two of the product's main advantages, allowing it to be used in both new installations and older systems, especially in the case of renovations.

Control panel features

• Summer/Winter/Off Selection
• Heating temperature regulator
• Sanitary temperature regulator
• Display of domestic hot water and heating temperature
• Display fault diagnostics and block status

Thermoregulation

To achieve class A+, it is necessary to connect a modulating thermostat to the boiler plus an external probe, which modulates the heating water temperature based on the external and internal temperatures, ensuring maximum comfort and optimizing consumption.
