The Biasi Dina 30C is a wall-hung condensing combi boiler delivering 30 kW of output for both central heating and instantaneous domestic hot water. Manufactured in Italy to Biasi's exacting standards, the Dina combines Gas Adaptive Technology, a stainless steel premix heat exchanger, and a compact 706 × 400 × 268 mm footprint — making it one of the most space-efficient condensing combis on the market. This pack pairs the boiler with the Biasi Vertical Flue Kit (Ø 60/100 mm, Part No. 10999.1163.0), ideal for loft or high-level installations where the flue must exit through the roof. The Dina is 20% Hydrogen Ready, features a 1:5 modulation ratio, is backed by a 5-year warranty (6 years for Pro-Fit registered engineers), and carries an ErP Energy Class A rating as standard — upgradable to A+ with an optional weather-compensation kit.
The eGarc combustion control system continuously analyses the flame signal and adjusts gas valve and fan to maintain optimal CO₂ levels at all times — regardless of supply gas quality or seasonal variation. A single boiler model covers both Natural Gas and LPG, simplifying stock and ordering.
The large-section oval coil primary heat exchanger is produced from high-grade stainless steel for long-term corrosion resistance. Its patented geometry promotes self-cleaning, reduces pressure losses, and makes system flushing straightforward — well suited to both new and retrofit installations.
At just 706 × 400 × 268 mm and 36.0 kg, the Dina is among the most compact 25 kW combis available — ideal for kitchen cupboards, utility rooms, and tight airing cupboards. The shallow 268 mm depth further simplifies cupboard-mount installations.
The backlit LCD display provides clear readout of DHW and CH set temperatures, live system pressure, and fault diagnostics. Summer/Winter/Off mode selection and separate CH and DHW temperature adjustment are managed via simple push buttons — straightforward for end users and installers alike.
The Dina is certified for operation on gas mixtures containing up to 20% hydrogen by volume, meeting the UK's commitment to blending hydrogen into the national gas grid. No hardware changes are needed to accommodate future grid hydrogen content up to this level.
The Dina is Wi-Fi ready for connection to the Biasi Connect app, enabling remote monitoring, temperature adjustment, and fault-code visibility from a smartphone. The optional modulating weather-compensation probe unlocks the full ErP A+ energy class.
