The Haier gas boiler of a Chinese manufacturer deserves attention. Do not think that this is a low-grade product, akin to Chinese consumer goods. The Hayer trademark is a worthy competitor of European gas equipment.
About company.Haier Group is a powerful brand that produces a variety of household appliances: from washing machines to heating boilers. Over three decades, the company has undergone significant transformations: the state-owned enterprise has transformed into a giant corporation. The headquarters of the company is located in Qingdao (China). The corporation has at its disposal 5 research centers with extensive links with research institutes and universities around the world. The brand occupies 17% of the global market in the segment of boilers and gas boilers.
Wall models
The manufacturer offers identical mounted models L1P18-F21, L1P20-F2 and L1P26-F2, characterized by the power on which the performance of the device and the area heated by it depend. All other characteristics and design features are the same.
Any Hayer heater is different:
- Stylish design. The body is white, the thoughtful location of automation. He will not ruin the interior.
- Reliability. Customer reviews indicate that Hyer has only one problem - the sensitivity of the control board to power surges. But such a drawback is inherent in most imported boilers. Other nodes are functioning properly. Water heats up quickly, and the temperature in the DHW circuit does not depend on the pressure in the water supply system or on the number of actively operating water intake points.
- Innovative solutions. Thanks to the closed firebox, the Hayer boilers do not consume air from the room to burn fuel. The presence of two separate heat exchangers allows you to quickly and evenly heat water for domestic use. All processes are monitored by automation with high sensitivity. The connection of a room temperature sensor is provided. There is a programming mode of work for a day ahead.
Device
A characteristic difference of all brand heaters is a closed combustion chamber and two circuits. Technical characteristics of turbocharged double-circuit boilers are predetermined by their internal structure:
- Efficiency at the level of 86–90%. This is not bad for heaters of this class, but much lower than that of condensation models, which have an efficiency of up to 90%. Hyer heaters, having a heating capacity of 20 kW, consume no more than 2 m³ / h of natural gas. This is an average for devices without a condensing module.
- Today, many boilers are equipped with bithermic heat exchangers, this reduces the cost of production, but the water in them is heated more slowly. Equipment with two circuits can operate in summer mode, which reduces gas consumption.
- Built-in automation monitors the operation of all nodes. Provides control over the presence of fire, traction, pressure in the pipes. If a deviation to a critical value is detected, the automation signals the user about the problem - the error code is displayed.
- The device is set up at the factory. If the user wants to change the settings, this can be done: you need an instruction that details the mechanism for adjusting the specified parameters.

Haier aries
Mounted turbocharged devices. The series consists of three models of 18, 24 and 28 kW. In appearance they are all the same. The sizes are the same. The marking indicates power. For example, the model BG-24ASg-tf has a power of 24 kW and is capable of heating 60 m². The heating rate is 2.5–15 l / min (at t = 25 ° C). Expansion tank - 6 l. The pump lifts the fluid 5 m, and on the BG-28, 6 m.
The series is generously equipped with additional functionality. As a rule, multifunctionality is found in powerful devices that heat 200–250 m². Here, all models, regardless of power, are equipped with all automation systems. Electronic control allows you to save fuel, and a timer - to program the temperature according to the time of day for each day of the week. If desired, a controller and a thermostat are connected to the heater, interacting with the solar collector.

To buy or not?
Haier gas equipment has permission from the Russian Technical Supervision Authority for operation by ordinary consumers. These devices, full of automation and innovative solutions, require appropriate maintenance. Buying such boilers, this applies to all imported analogues, is only possible if you can contact the service center with the appropriate certification.
Faults and error codes
Error E1 - the flame disappeared. What to do? Check if gas is supplied to the burner. Verify that the gas valve is in good condition. Try to start the device. Doesn't turn on? Need to contact the service.
Another reason for the lack of flame is a malfunction of the control board, because of which the ignition electrode does not work. When starting up, the gas pressure drops dramatically and the flame does not ignite. It happens that E1 occurs already during the first start, then the cause may be increased humidity. What to do? Take an electric hair dryer and dry the electrode, and at the same time the terminals.
E2 - the system has overheated. Check if you need to open the tap in the heating system. Clogged filters can also cause overheating, check them and clean them if necessary.
E3 - The fan is broken and there are problems with traction. How to be? Check if the fan and venturi (flow meter) are working properly. The second possible reason is a breakdown of the relay that responds to changes in air pressure. Also check the fan: if it is clogged or broken, clean or replace accordingly.
It happens that the error E3 appears too often. The likely reason is the excessive length of the chimney. With natural traction, the problem is associated with overheating of the upper part of the furnace. If the heating exceeds 70 ° C, the thermostat is activated. Solution - wait until the temperature drops.
E4 - there is no water in the boiler or its flow is insufficient. Probably, the pressure has fallen, need recharge up to 1-1.5 bar. The second cause of the malfunction is a breakdown of the flow switch.
E6 - Damage to the DHW sensor or pressure drop. The solution is to recharge the system: it is necessary that the pressure rises to 1–1.5 bar.
E7 - The DHW sensor is faulty or the cable is broken.
E9 - lowering the temperature below 2 ° C. Turn on and off the machine. This error applies exclusively to the heating system.
In newer models, the error codes are slightly different. So, for example, the F5 code signals a screen malfunction. Details about all errors and their deciphers can be found in the instructions.
Operational Features
Correct operation of automated equipment is possible only with a professional approach to installation and maintenance. Service employees comply with all boiler installation rules, which is a guarantee of their uninterrupted operation. Operating Rules:
- Have annual maintenance.
- Maintain a water pressure of at least 1 bar.
- Ensure uninterrupted operation of safety devices - sensors, relays and other automation elements. In case of breakage, replace them promptly.
- Check and clean burners and heat exchanger regularly.
- Ensure that there are no leaks in the water and gas pipes.
- Adjust pressure and performance based on appropriate tables.
- Keep the pump running smoothly without interruptions or blockages.
How to clean Haier boilers
Hyer heaters do not need special care; it is enough to wash them at the end of each season. Do not use chemicals or hard brushes. After cleaning, it is important to check the operation of all systems, especially the ignition process, the operation of the thermostat, pump, gas valve. Check for leaks.
Reviews
Falco L1P26-F21 (T): Irina G., Pavlovo
They paid 25,000 rubles. This, of course, is less than what is requested for German and other European counterparts. When choosing, they drew attention to the compactness of the device, its efficiency and safety - in Hayer all three indicators coincided. Also attracted by simple and intuitive controls. Not afraid of power surges, it works without failures, the power is enough for heating our spacious apartment.
Haier Aquila L1P26-F21O (T): Nikita P., Pervomaisk
During operation, no flaws were found. We heat the house 180 squares. Three water points are connected. Not afraid of power surges, does not go out, reliable security system - you can sleep peacefully. It works even at very low gas and water pressures. Full automation, easy to use. After turning off the light, all settings are restored.
The Haier brand represents a wide range of domestic gas heaters, designed primarily for small to medium-sized rooms. All models are equipped with two circuits and provide, in addition to heating, hot water supply. Hayer products are reliable, meet current requirements, have an affordable cost and deserve the attention of consumers.
