[0002] A wall-mounted boiler is actually the abbreviation of a gas wall-mounted boiler. It is not a gas water heater in the traditional sense and is essentially different from a water heater. It has multiple safety protection measures such as anti-freeze protection, anti-dry burning protection, accidental flameout protection, over-temperature protection, and water pump anti-stuck protection. It can be connected to an external indoor thermostat to achieve personalized temperature adjustment and energy saving.

[0003] Announcement No. CN219301009U discloses a segmented combustion gas wall-mounted boiler, which can control the combustion power and size of the device according to demand by dividing the combustion chamber into multiple unit combustion chambers, solving the problems of insufficient energy utilization, waste, and inconvenient adjustment of combustion power of the current device. However, when adjusting multiple unit combustion chambers, it is necessary to turn the valves on different gas branches to control the size of the intake air volume. Due to the large number of valves, it is troublesome to turn them.

[0004] Therefore, we propose a wall-mounted boiler with adjustable power to solve the above-mentioned problems. Utility Model Content
