- Low-frequency noise suppression design lowers running noise for quiet indoor use.
- The water flow signal adopts pulse collection to detect water demand accurately.
- The boiler has a dedicated dosing port for adding condensate neutralizer chemicals.
- The combustion chamber lining is made of high-temperature insulation material to reduce heat loss.
- The temperature hysteresis value can be adjusted to suit different heating comfort needs.
The built-in circulating pump drives heating water through radiators or floor heating pipes. Pump speed is adjustable to match the different loop resistance of large or small heating systems. An anti-blocking function activates regular rotation to prevent the impeller from sticking due to rust after long idle periods.
The internal pipeline supports a wide range of working temperature cycles and pressure fluctuations. All internal copper pipes are treated with a stress relief annealing process after bending, eliminating internal stress generated during pipe forming. This prevents pipe cracking caused by repeated thermal expansion and contraction over the years.
Welding joints adopt silver brazing technology, forming solid, leak-proof weld seams with good ductility. Every welded joint is visually inspected and pressure tested during production. The pipeline layout reduces unnecessary sharp bends to lower water flow resistance, helping the built-in circulating pump operate with less power consumption. Pipe fixing clips with rubber damping pads reduce vibration transmission from the pipes to the boiler shell, cutting resonance noise and protecting weld joints from fatigue fracture caused by long-term vibration.
A1: Pipeline sealing gaskets adopt heat-resistant and anti-aging rubber material.
A2: The flue terminal cap adopts a rainproof design to block rainwater ingress.
A3: The air intake silencer weakens air intake noise during combustion.
A4: A built-in automatic air vent valve helps exhaust air inside the heating loop.
A5: It matches an ordinary bath mixer, relying on the boiler's internal constant temperature.
A6: The ignition trial limit function stops sparking after a fixed number of retries.
