Condensing boilers ENERGEIA

Key strengths

Self-cleaning stainless exchanger

Stainless-steel condensing heat exchanger with self-cleaning function: consistent performance over time, less maintenance.

A-rated efficiency

Efficiency up to 107.8% (30/50 °C regime): flue-gas heat is not wasted — it is reused.

Premix burner, NOx class 6

Total premix stainless-steel burner: emissions among the lowest in the category.

1:5 modulation

Output always proportional to demand, for constant comfort and fewer ignition cycles.

One model, two gases

A single model runs on NATURAL GAS and LPG.

Low-consumption modulating pump

Frequency-modulating circulator for maximum electrical efficiency.

Digital controls

Digital control panel with backlit display; ready for modulating thermostat, remote control and outdoor probe.

Compact

Just 710×420×260 mm: fits anywhere, including replacements.

Stainless-steel primary heat exchanger

The primary exchanger is a compact, large-section oval mono-spiral made with self-cleaning technology. The patented high-efficiency flue-gas circuit and the single combustion chamber allow total cleaning of the exchanger; the smoke box is made of high-performance composite material.

The water flow is uniformly distributed, guaranteeing homogeneous heat exchange. Pressure losses are reduced thanks to the exchanger's large section. Easy cleaning and robustness make it suitable for both new and older installations.

Gas Adaptive Technology

The adaptive system automatically detects the characteristics of the gas and adjusts combustion to maximise efficiency, reducing consumption and emissions. Automatic combustion analysis, no external instruments needed.

⬡ H₂ Ready — certified to run on blends of up to 20% hydrogen.
