Product Description

Product Introduction

This electric wall-mounted boiler presents a clean, utilitarian yet modern design tailored for residential spaces. Its main body features a smooth, matte white metal panel—durable, easy to clean, and versatile enough to blend with most interior decor, from minimalist kitchens to compact utility closets. At the top right corner, a small blue-and-white label (with a QR code and product information) adds a functional touch without disrupting the appliance's streamlined look. The lower section integrates a compact, oval-shaped control module: this area includes a circular digital display (showing operational data like temperature or settings), a central knob, and several physical buttons (for power, mode selection, and adjustments). The wall-mounted structure ensures it occupies minimal floor space, while the vertical, rectangular form factor (standard for wall-mounted boilers) allows for easy installation in tight areas. The overall design prioritizes practicality and simplicity, avoiding excessive ornamentation to maintain a sleek, unobtrusive profile that fits seamlessly into daily living environments.

Function

As a residential heating and hot water solution, this electric wall-mounted boiler offers dual-purpose functionality with user-friendly controls. For central heating, it supports systems like radiators or underfloor heating, with adjustable temperature ranges (typically 30–80°C) to accommodate different room sizes and comfort preferences; users can fine-tune settings via the control panel to match seasonal needs (e.g., higher temperatures in winter, lower in milder weather). For domestic hot water supply, it provides on-demand, stable hot water (with temperature control up to 60°C) to meet daily needs like showering, dishwashing, or laundry—eliminating the need for a separate water heater. The control module enables basic programming (e.g., setting heating schedules) to align operation with daily routines, reducing energy waste by avoiding unnecessary runtime. 

Advantages

This electric wall-mounted boiler offers several key advantages for modern households, starting with its energy efficiency and ease of use. Unlike gas-powered models, it produces zero on-site emissions, making it a cleaner choice for indoor air quality—ideal for homes in areas with strict environmental regulations or limited gas access. Its electric operation also simplifies installation (no need for gas lines or venting) and reduces long-term maintenance costs (fewer moving parts than gas boilers). The compact, wall-mounted design saves valuable floor space, a critical benefit for small apartments or homes with limited utility areas. The intuitive control panel (with a digital display and physical buttons) ensures accessible operation for users of all ages, while safety features like anti-overheating and anti-freezing provide peace of mind.

FAQ

1. Q: How to choose the power of the wall-mounted boiler to match my home layout?

A: For ordinary residential buildings of 80-150 square meters, choose 24KW, which can meet the heating and hot water needs of one kitchen and two bathrooms; Choose 28KW or above models for 150m2 or larger floor-to-ceiling units or villas; For homes in the south without insulation or those with multiple bathrooms, it is recommended to increase the power by 20% to 30% to avoid insufficient hot water or heating.

2. Q: Does the online purchase of a wall-mounted boiler include installation services? How much is the charge for auxiliary materials?

A: Most online shopping models of brands include free basic installation, but do not include special fees such as high-altitude work and wall drilling. Auxiliary materials such as pipes, corrugated pipes, and filters need to be purchased separately. The total cost of auxiliary materials and special installation fees is usually around 1,000 yuan, and you can consult customer service to confirm the details of the package.

3. Q: Can a dual-purpose wall-mounted boiler provide both heating and hot water at the same time?

A: It can't run at the same time, the hot water function will start first. The machine will automatically switch between heating and hot water mode according to the opening of the hot water faucet, and the heating will be temporarily suspended when taking a bath, and the heating will resume after the hot water is turned off.

4. Q: Is there a big difference between first-class energy efficiency and ordinary wall-mounted boilers? Is it worth spending more money to buy it?

A: The main difference lies in energy efficiency. Most of the first-class energy efficiency is condensing wall-mounted boilers, and the thermal efficiency can reach more than 107%. It can save 15% to 20% of the gas fee compared with ordinary non-condensing boilers. It is very cost-effective to use it for a long time, especially for large houses or families who use hot water for a long time, and the saved gas fee can quickly cover the difference.

5. Q: The old house doesn't have pre-installed heating pipes, can I install this wall-mounted boiler?
A: Sure. For old houses or houses that have already been renovated, you can choose the open-air radiator system, which does not need to damage the walls and decoration during construction, has a short construction period, and has a good appearance after installation. After placing the order, you can book a master to measure and design the installation plan at home.

6. Q: Is there any after-sales guarantee for the product? How long is the warranty period?
A: The product strictly adheres to the national "three guarantees" policy. The main model is guaranteed for 3-5 years, and the core components such as heat exchanger and water pump are guaranteed for 8-10 years. There are official authorized after-sales outlets nationwide, and after reporting a problem, a technician will be arranged to come to the door for inspection. You can contact customer service to inquire about the location of local outlets.
7. Q: Can the wall-mounted boiler still heat normally after the water supply is cut off?
A: It can heat normally. The heating system is a closed water circulation system, which does not need to be filled with water in real time, and water stop does not affect its operation; However, hot water depends on the supply of tap water, and it cannot be used after the water supply is cut off.
8. Q: How to prevent the wall-mounted boiler from freezing when no one is at home for a long time in winter?
A: When you go out for a short time, you can turn on the machine's anti-freezing mode, keep the power and gas on, and the equipment will automatically maintain a low temperature to prevent freezing. If you are away from home for a long time, it is recommended to turn off the water, electricity and gas, drain the water in the machine and pipes, and avoid water freezing and damaging the parts.

9. Q: Does the wall-mounted boiler consume a lot of electricity? Will it consume a lot of electricity during operation?
A: It doesn't consume much power. The main power-consuming components are the fan and the water pump, with a rated power of only 100-200W, and they do not run continuously; they are synchronized with the start-up and shutdown of the heating system, and the monthly power consumption is roughly the same as that of a household refrigerator.
10. Q: Can I return or exchange the product if I find that the model is not suitable after receiving the product?
A: We support a 7-day no-reason return and exchange if the product has not been opened and does not affect resale. If it has been opened or scheduled for installation, it may need to bear the cost of installation and auxiliary material loss if it is not a quality issue, and it is recommended to confirm the compatible model before placing an order.
