Product Advantage

High-Efficiency Heat Preservation

Our water tank is designed with high-density insulation to reduce heat loss and keep stored hot water at a stable temperature for longer periods. The thick insulation layer helps improve overall system efficiency, especially when working with air source heat pumps, solar heating systems or commercial hot water projects. By reducing unnecessary reheating, the tank helps lower daily energy consumption and improve user comfort in homes, hotels, apartments and other hot water applications.

Reliable Heat Exchange Performance

The water tank can be equipped with a built-in heat exchange coil to transfer heat efficiently from the heat pump or solar system to the stored water. A well-designed coil structure increases the contact area and supports faster heat transfer, helping the system reach the target water temperature more efficiently. This makes the tank suitable for residential and commercial projects that require stable, continuous hot water supply.

Durable Tank Structure for Long Service Life

The tank body is built for long-term hot water storage and daily operation. According to different market requirements, the inner tank material and coating can be customized to improve corrosion resistance and water quality protection. A strong outer shell and reliable pressure-bearing structure help ensure safe operation under different installation conditions. This makes the product suitable for both household use and commercial hot water systems with higher water demand.Durable Tank Structure for Long Service Life

4. Flexible System Compatibility

Water Tank Installation Instructions

1. Site Preparation

Choose a flat, stable and well-ventilated installation area. Make sure there is enough space around the water tank for pipe connection, inspection and future maintenance. The foundation should be strong enough to support the tank when it is fully filled with water.

2. Pipeline Connection

Connect the cold water inlet, hot water outlet, drainage port and circulation pipe according to the system design. If the tank works with a heat pump or solar system, connect the heat exchange coil correctly to ensure smooth water circulation and efficient heat transfer.

3. Electrical & Sensor Installation

Install the temperature sensor, electric backup heater or control cable if required. All electrical connections should be completed by qualified technicians. Make sure the wiring is secure, waterproof and compliant with local electrical safety standards.

4. Water Filling & Pressure Check

Open the water inlet valve and fill the tank slowly. Check all pipe joints, valves and connection ports for leakage. After the tank is full, release the air from the system and confirm that the water pressure is within the normal operating range.

5. System Testing

Start the heat pump, solar system or other heating equipment connected to the tank. Check the water temperature, circulation performance and control settings. After testing, confirm that the whole hot water system runs smoothly before regular use.
