Electronic Controller
The controller supports accurate temperature control and efficient operation. It also includes multiple safety protections, user-friendly controls, and built-in fault detection to make troubleshooting and maintenance easier.

Sealed Combustion Chamber
The sealed combustion chamber is designed with insulation and sound-reducing materials to help protect internal parts and reduce noise. The H-series wall-hung boilers also use additional noise-control measures, with sound levels that can be as low as 42 dB(A)*.

Noritz Water Pump
Noritz water pumps are designed for quieter operation to improve comfort in daily use. They also include smart self-protection features that help reduce the risk of faults over time.

Sectional Valve
The sectional valve supports staged combustion control, so flame output can be adjusted in steps. This makes control more stable and more precise during operation.

Five-Stage Heat Exchanger Design
A five-stage heat exchanger structure helps keep the overall size compact while improving heat transfer. Thanks to the larger main tubes and a longer heat-exchange path, more heat can be captured and used efficiently.

Italian SIT Proportional Valve
A proportional valve from the Italian brand SIT is used to adjust gas flow and pressure. Since the adjustment is more precise and reacts quickly, the burner can run more smoothly and waste less gas, which improves efficiency.

Expansion Tank
The expansion tank helps absorb pressure changes in the water circuit as temperatures rise and fall. By keeping pressure more stable, it protects key components and supports more consistent operation over time.
