Energy Saving Gas Water Heater for Home Hot Water

Product Description

Product Introduction

The WSA3-type gas heating hot water stove features a sleek, minimalist rectangular design with a smooth matte white finish, crafted to integrate unobtrusively into residential spaces like kitchens or utility rooms. Its wall-mounted structure saves floor space, while the clean, vertical profile maintains a modern, understated aesthetic. At the top, a circular metallic vent handles exhaust, and the brand logo is displayed prominently in the upper section. Below this, a small horizontal slot (likely for status indicators) sits above a distinctive black oval control zone—this zone houses a circular digital display (showing temperature, time, and settings) and intuitive buttons (for power, temperature adjustment, and mode selection). The contrast between the white body and black control panel adds visual definition, balancing functionality with a polished, contemporary look.

Function

As a dual-purpose appliance, the WSA3 gas heating hot water stove provides both central home heating and on-demand hot water. Powered by gas (natural gas or LPG), it uses efficient combustion to heat water: the heated water circulates through radiators or underfloor systems to warm living spaces, or is delivered directly to taps, showers, and appliances (eliminating the need for a separate hot water storage tank). The digital control panel allows users to adjust heating temperatures, set operational schedules, toggle between heating and hot water modes, and monitor system status in real time. Built-in safety features (consistent with standard gas appliance regulations) include flame failure protection, overheat shut-off, and pressure regulation, ensuring safe, reliable performance in domestic environments.

Advantages

The WSA3 gas heating hot water stove offers several key advantages for homeowners. Its dual-function design combines heating and hot water systems into one compact unit, reducing installation costs and saving valuable floor space—especially beneficial for small homes or apartments. The premium gold finish adds a decorative element, allowing the appliance to blend into (or enhance) interior design rather than appearing as a purely functional fixture. Gas-powered operation is cost-effective, typically more affordable than electric alternatives, and its on-demand hot water delivery minimizes energy waste (unlike storage tanks that continuously reheat water). The intuitive control system ensures easy operation, while built-in safety features provide peace of mind. Overall, this appliance balances style, space efficiency, cost-effectiveness, and functionality, making it a versatile and aesthetically pleasing choice for residential heating and hot water needs.

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.
