Product Description
This wall-mounted combi gas boiler features an optimized internal air flow channel design that reduces condensation risk inside the combustion chamber during low-temperature heating operation. Condensation, if not drained properly, will gradually corrode metal components. A built-in condensate drain port collects condensed water produced during combustion, and the condensate outlet can be connected to a household sewage pipe.
For the non-condensing version, the structure resists mild condensate formed under partial load, and internal metal parts adopt an anti-corrosion coating to resist weak acid condensate. When the boiler operates at low supply temperatures for floor heating, the possibility of condensation rises. The improved structure effectively guides condensed water out of the combustion area and prevents condensate backflow onto the burner surface, protecting the burner and heat exchanger from acid corrosion and extending the whole machine's service life under long-term low-temperature heating conditions.
- Condensate drain port for optional condensing version application.
- High heat recycling rate on condensing model for extra gas saving.
- Connector terminals with anti-oxidation coating for stable contact.
- Humanized UI menu with simple navigation for new users.
- Custom logo printing service available for OEM and ODM orders.
The integrated expansion tank stabilizes pressure fluctuation of the closed heating loop. When heating water expands with rising temperature, the extra volume is absorbed by the expansion tank to avoid pressure spikes. This prevents frequent pressure relief and water supplement. The built-in design simplifies pipeline layout and reduces extra accessory purchases.

Q1: What tests are performed before shipment?
A1: Water pressure test, air tightness test, ignition test, and full load aging test.
Q2: Does each boiler have a unique serial number?
A2: Yes, each boiler is assigned a serial number for production traceability.
Q3: Can you supply a boiler with a built-in zero cold water function?
A3: Yes, a zero DHW recirculation model is available as an option.
Q4: What is the difference between a zero cold water combi boiler and a standard combi boiler?
A4: The zero cold water model includes a built-in recirculation pump, so hot water arrives instantly without waiting for cold water in the pipe to clear.
Q5: Does the zero cold water model require a return pipe?
A5: It works best with a dedicated return pipe, but it can also operate without one by tapping into the cold pipe.
Q6: Can the boiler work with a solar water heating system?
A6: Yes, a solar interface is available for auxiliary heating.
