Product Description
This wall-mounted combi gas boiler integrates central heating and domestic hot water supply into one compact unit. It heats water on demand without a bulky storage tank, saving precious indoor space for apartments and villas. With high thermal efficiency above 92%, it cuts gas consumption and lowers monthly utility bills. The dual-circuit design smoothly switches between heating mode and hot water mode, ensuring stable output for radiators or underfloor heating systems all year round.
- Adopt advanced sealed combustion chamber for safer and cleaner gas burning.
- Class 1 energy efficiency rating reduces gas consumption and household bills.
- Dual function for space heating and instant domestic hot water supply.
- Low NOx combustion technology meets strict environmental emission standards.
- Built-in multi-stage fire modulation adjusts power according to heat demand.

This wall-mounted combi gas boiler solves the common household pain point of unstable shower water temperature. High-speed water flow and temperature sensors capture water opening signals instantly, while the PID intelligent control algorithm adjusts gas supply rapidly to stabilize outlet water temperature. Even if multiple water taps are opened simultaneously in different rooms, the temperature remains steady without sudden hot or cold surges.
The product supports low water pressure startup, which is highly suitable for high-rise buildings and communities with unstable tap water pressure. A detachable inlet filter traps sand, rust, and sediment to protect internal valves, flow sensors, and heat exchangers from abrasion and blockage.
Winter and summer dual-mode switching is available on the control panel. In summer mode, only domestic hot water activates while the heating circuit pauses; winter mode enables both heating and hot water with hot water priority. The unit also includes a power-off memory function, retaining all user settings automatically once power recovers after a blackout, removing repeated parameter reset work for users.
A1: It is a 2-in-1 unit that supplies both central heating and instant domestic hot water without an extra hot water storage tank.
A2: Standard for natural gas; an LPG version is available after replacing the gas nozzle and adjusting the gas valve.
A3: We supply both options: a high-efficiency condensing type and an economical non-condensing model.
A4: Yes. The installer can set the maximum heating supply temperature to protect the floor screed.
A5: When water flow is detected, the boiler switches to DHW mode, and heat exchange occurs on the plate heat exchanger.
A6: Yes, a variable-speed circulating pump is integrated inside.
