Heat Pump Water Tank for Hot Water Storage and Heat Exchange

Legend Heat Pump Water Tank is designed for residential, commercial, and industrial hot water applications. Featuring a single-coil heat exchange structure, it supports efficient thermal transfer and provides dependable hot water storage for air source heat pumps and other heating applications. With flexible capacity options, stainless steel material choices, and customized coil configurations, it meets different project requirements while supporting consistent hot water supply.

Efficient Single-Coil Heat Exchange Design

The internal coil structure plays an important role in heat pump water heating performance. Legend adopts a carefully arranged single-coil design to promote fast and uniform heat exchange between the heating medium and stored water. This helps improve thermal conversion efficiency and supports stable hot water preparation under varying operating conditions.

Different coil configurations are available to accommodate specific heating requirements, including flat coils, wave coils, and refrigerant system coils. These options allow buyers to select a suitable heat pump hot water tank according to equipment compatibility, heat transfer requirements, and project design.

Stainless Steel Inner Tank for Long-Term Durability

Material selection directly affects the service life and application suitability of a hot water storage tank. Legend offers inner tanks manufactured from SUS304, SUS316L, and Duplex 2205 stainless steel. These materials provide different levels of corrosion resistance and mechanical strength, allowing customers to match the tank construction with water quality and operating conditions.

The outer shell is available in painted galvanized steel or stainless steel, with multiple color finishes. Combined with carefully controlled welding and manufacturing processes, these options provide flexibility for different installation environments and project specifications.

Thermal Insulation for Reduced Heat Loss

Effective insulation helps maintain stored water temperature and reduce unnecessary thermal energy loss during standby periods. Legend Heat Pump Water Tank uses a 45–50 mm foam insulation layer to support heat retention and improve overall thermal performance.

Insulation quality is particularly important for domestic hot water applications where water may remain stored between periods of consumption. Proper insulation helps reduce the frequency of reheating requirements and supports more consistent hot water availability.

Flexible Capacities for Different Applications

Different buildings and facilities have different hot water consumption patterns. Legend provides heat pump water tank capacities ranging from 60L to 2000L, covering small residential installations as well as larger commercial and industrial projects. Combined tank configurations are also available for applications requiring additional functional flexibility.

The available options make it easier for distributors, contractors, and project developers to select a suitable domestic hot water storage tank based on daily demand, installation space, and heating equipment capacity.

Customization and Manufacturing Capabilities

As an experienced water tank manufacturer, Legend supports customization of tank dimensions, inner materials, outer shell finishes, openings, flanges, and heating coil structures. Precision laser cutting helps achieve smooth edges and accurate dimensions, supporting consistent component fitting and reliable welding quality.

With 17 years of professional welding experience and certified welders, Legend maintains strict manufacturing quality control. Each tank undergoes 100% online leakage testing, followed by a three-minute pressure-holding inspection. Products are backed by a three-year warranty, providing additional assurance for international distributors and project purchasers.

Wide Applications of Heat Pump Water Tanks

Legend Heat Pump Water Tank is suitable for residential domestic hot water supply in villas, apartments, and residential communities. Its storage capacity and heat exchange structure also support commercial hot water projects in hotels, schools, hospitals, factories, and shopping centers.

For air source heat pump applications, the tank provides an integrated storage and heat exchange solution. It can also be incorporated into central heating applications where additional hot water storage is required to support stable heating performance.
