Description

12 kW tankless electric water heater from Zanskar Hotspring™ is a high-performance on-demand water heating solution designed for Indian homes requiring fast and convenient hot water. The Zanskar Hotspring 12 kW model uses nickel-chromium heating elements, a digital LED temperature display, touch-screen controls and multiple built-in protection features. It operates on a 440 V three-phase electrical supply and supports vertical or horizontal installation.

The Zanskar Hotspring tankless system heats water as it flows through the appliance, eliminating the need to store a large volume of preheated water. This compact design helps save installation space while providing hot water when required. Zanskar’s tankless range is designed for bathrooms and other domestic hot-water applications, with the 12 kW model positioned for higher hot-water demand than the lower-power models.

Zanskar Hotspring 12 kW Tankless Electric Water Heater

The appliance combines a high-strength ABS cover casing with stainless-steel heating elements and a digital user interface. The LED display shows the outlet water temperature, while the touch-screen control allows convenient temperature adjustment. An automatic thermostat helps regulate operation, and the automatic memory function can retain the preferred temperature setting for convenient everyday use.

The patented heating module system incorporates several protection features, including electricity leakage protection, anti-scalding protection, overpressure protection and overheat protection. The appliance also provides an error-code display to help identify operating conditions when required.

Fast On-Demand Hot Water

Unlike a conventional storage water heater, a tankless electric water heater does not need to maintain a large stored volume of hot water. The Zanskar Hotspring 12 kW model heats water as it passes through the heating module, making it suitable for applications where on-demand hot water and compact installation are important.

The 12 kW output provides substantially higher heating capacity than small point-of-use instant heaters. Actual hot-water flow and outlet temperature will depend on incoming water temperature, flow rate and installation conditions.

Digital Temperature Control

The built-in LED digital display makes the outlet temperature easy to monitor. The touch-screen interface allows the user to set the desired water temperature directly. The automatic thermostat helps maintain controlled operation, while the memory function reduces the need to repeatedly enter the preferred setting.

Compact 2-Way Installation

Despite its 12 kW heating capacity, the appliance has a compact body measuring approximately 396 × 220 × 88 mm (height × width × depth). It supports vertical or horizontal installation, providing greater flexibility when planning the available wall space.

Installation orientation, electrical connections, plumbing and commissioning should always be carried out according to the manufacturer’s instructions and by a suitably qualified professional.

Safety and Protection Features

The Zanskar Hotspring 12 kW tankless electric water heater incorporates several built-in protection functions intended to improve operational safety:

• Electricity leakage protection through the appliance’s protection system.
• Anti-scalding protection to help control excessively hot outlet water.
• Overheat protection for protection against excessive temperature.
• Overpressure protection for operation within the specified pressure limit.
• Automatic thermostat for temperature control.
• Thermal cut-out listed in the product specifications.
• IP25 protection rating for the appliance.
• Error-code display for easier identification of operating conditions.

The stated maximum water pressure is 6 bar. Do not install or operate the appliance outside the manufacturer’s specified electrical, water-pressure or installation requirements.

12 kW Three-Phase Electrical Requirement

The 12 kW model is a high-power electrical appliance and requires a 440 V three-phase supply. The listed wiring specification is 5 × 6 mm². The electrical installation must be appropriately designed, protected and earthed for the appliance’s rated load.

Important: This is not a standard single-phase plug-in water heater. Before purchase and installation, confirm that the property has a suitable three-phase electrical supply and that the wiring, protective devices, earthing and other electrical infrastructure are appropriate for a 12 kW load. A qualified electrician should verify the installation before commissioning.

Technical Specifications

Where Can You Use a 12 kW Tankless Water Heater?

The Zanskar Hotspring 12 kW tankless electric water heater is intended for domestic hot-water applications where a higher heating capacity and continuous on-demand operation are required. It can be considered for suitable residential bathroom installations where the electrical supply and expected water flow are compatible with a 12 kW three-phase appliance.

Before selecting the 12 kW model, consider the local winter water temperature, incoming water temperature, shower flow rate and desired outlet temperature. Higher flow rates and colder incoming water require greater heating capacity to achieve the same outlet temperature.

Why Choose a Tankless Electric Water Heater?

A tankless water heater heats water when there is a demand rather than maintaining a large tank of stored hot water. This can reduce standby heat losses associated with storage systems. However, a high-power electric tankless heater can require significant electrical capacity while operating, so the electrical infrastructure must be suitable for the selected model.

Installation and Safety Information

Because this is a 12 kW, 440 V three-phase water heater, professional installation is strongly recommended. The electrical supply, cable size, protective devices, earthing and plumbing arrangement must be checked before the appliance is commissioned.

• Verify that a suitable 440 V three-phase supply is available.
• Use the specified 5 × 6 mm² wiring, subject to confirmation by the installation professional and applicable electrical requirements.
• Ensure proper earthing and suitable electrical protection.
• Confirm that water pressure does not exceed the specified 6 bar maximum.
• Follow the manufacturer’s approved vertical or horizontal installation orientation.
• Check all water connections for leakage before electrical commissioning.
• Do not modify the appliance’s electrical or safety systems.
• Keep the appliance accessible for inspection and servicing.
• Have the installation inspected and commissioned by a qualified electrician.
