Газовый котел Haier китайского производителя заслуживает внимания. Не стоит думать, что это низкосортный товар, сродни китайскому ширпотребу. Торговая марка «Хайер» — достойный конкурент европейского газового оборудования.
About company. Haier Group is a powerful brand that produces a variety of household appliances: from washing machines to heating boilers. For three decades, the company has undergone significant transformation: a state-owned enterprise has transformed into a giant corporation. The company’s headquarters is located in Qingdao (China). The corporation has 5 research centers with extensive connections with research institutes and universities around the world. The brand occupies 17% of the world market in the segment of boilers and gas boilers.
Wall models
The manufacturer offers identical hinged models L1P18-F21, L1P20-F2 and L1P26-F2, differing in 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. White body, well-thought-out arrangement of automation. It won’t ruin the interior.
- Reliability. Consumer reviews indicate that Hayer has only one problem – the sensitivity of the control board to power surges. But such a disadvantage is inherent in most imported boilers. Other nodes are functioning properly. The water heats up quickly, and the temperature in the DHW circuit does not depend on the pressure in the water supply system, nor on the number of active water intake points.
- Innovative solutions. Due to the closed firebox, Hayer boilers do not consume air from the room for fuel combustion. The presence of two separate heat exchangers allows you to quickly and evenly heat water for domestic needs. All processes are monitored by automation with high sensitivity. Connection of the room temperature sensor is provided. There is a mode of programming work for the day ahead.
Устройство
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:
- КПД на уровне 86–90%. Это неплохо для нагревателей такого класса, но гораздо ниже, чем у конденсационных моделей, которые имеют КПД до 90 %. Нагреватели «Хайер», имея теплопроизводительность 20 кВт, потребляют не более 2 м³/ч природного газа. Это средний показатель для устройств, не имеющих конденсационного модуля.
- 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, draft, pressure in the pipes. If a deviation to a critical value is detected, the automation signals the user about the problem – the display shows an error code.
- The device is configured at the factory. If the user wants to change the settings, this can be done: you will need an instruction that details the mechanism for adjusting the specified parameters.

Here, all models, regardless of power, are equipped with all automation systems. Electronic control allows you to save fuel, and the timer allows you 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 a permit from Rostekhnadzor of the Russian Federation 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 worth contacting a service center with the appropriate certification.
Faults and error codes
Error E1 – The flame is gone. What to do? Check if gas is supplied to the burner. Make sure the gas valve is working. Try to start the device. Doesn’t turn on? You need to contact the service.
Another reason for the absence of a flame is a malfunction of the control board, which is why the ignition electrode does not work. When starting, 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 high 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 a 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 the condition of the fan and venturi tube (flow meter). The second possible reason is a breakdown of the relay that reacts to changes in air pressure. Also check the fan: if it is clogged or broken, clean or replace accordingly.
It happens that the E3 error appears too often. The probable cause is the excessive length of the chimney. With natural draft, the problem is associated with overheating of the upper part of the firebox. If the heating exceeds 70°C, the thermostat is activated. The solution is to wait for the temperature to drop.
E4 – there is no water in the boiler or its flow is insufficient. Probably, the pressure has dropped, you need to recharge up to 1–1,5 bar. The second cause of the malfunction is a breakdown of the flow switch.
E6 — поломка датчика контура ГВС или падение давления. Решение — подпитка системы: необходимо, чтобы давление поднялось до 1–1,5 бар.
E7 – the DHW sensor is faulty or the cable is broken.
E9 — lowering the temperature below 2°C. Turn the machine on and off. This error concerns only the heating system.
In new models, error codes are slightly different. So, for example, the F5 code indicates a screen malfunction. Details of all errors and their decryption can be found in the instructions.
Features of operation
Correct operation of automated equipment is possible only with a professional approach to installation and maintenance. Service employees follow all the rules for installing boilers, which is a guarantee of their uninterrupted operation. Operating rules:
- Get serviced annually.
- Поддерживать давление воды не менее 1 бар.
- Ensure the uninterrupted operation of safety devices – sensors, relays and other automation elements. In the event of a breakdown, they should be replaced promptly.
- Check and clean burners and heat exchanger regularly.
- Ensure that there are no leaks in water and gas pipes.
- Carry out pressure and capacity adjustments based on the relevant tables.
- Keep the pump running smoothly without failures or blockages.
How to clean Haier boilers
Heaters “Hayer” do not need special care, it is enough to rinse them at the end of each season. The use of chemicals and hard brushes is prohibited. After cleaning, it is important to check the operation of all systems, especially the ignition process, the operation of the thermostat, pump, gas valve. Make sure there are no leaks.
Reviews
Falco L1P26-F21(T): Irina G., Pavlovo
Paid 25 rubles. This, of course, is less than they ask for German and other European counterparts. When choosing, we paid attention to the compactness of the device, its efficiency and safety – all three indicators coincided in Hayer. Also attracted a simple and clear control. It is not afraid of voltage drops, it works without failures, the power is enough to heat our spacious apartment.
Haier Aquila L1P26-F21O(T): Nikita P., Pervomaisk
During the work, no shortcomings were found. We heat the house of 180 squares. Three points of water intake are connected. It is not afraid of power surges, does not go out, a reliable security system – you can sleep peacefully. 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 presents a wide range of household gas heaters, designed mainly for small and medium-sized premises. 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 price and deserve the attention of consumers.
