Description

Tankless electric water heater technology gives you hot water when you need it without the need for a conventional storage tank. The Stiebel Eltron DHC 8 EC (IN) is an electronically controlled instantaneous water heater designed to provide precise and consistent hot water temperature for suitable household applications.

Using temperature sensors and microcontroller technology, the DHC 8 EC (IN) electronically controls the outlet temperature. This helps maintain a stable water temperature during operation and can improve shower comfort when water demand changes at another connected outlet.

Stiebel Eltron DHC 8 EC (IN) Tankless Electric Water Heater

The Stiebel Eltron DHC 8 EC (IN) is an 8 kW tankless electric water heater featuring electronic temperature control and a compact design. Instead of continuously storing and heating a large volume of water, an instantaneous water heater heats water as it passes through the appliance.

The DHC EC series uses temperature sensors and microcontroller technology to regulate the outlet temperature. The rotary selector allows the user to choose from three temperature settings according to the required water flow and application.

For the current DHC 8 EC (IN) model information published by STIEBEL ELTRON India, the available temperature settings are 40 °C, 50 °C and 55 °C. This specification has been used here instead of the previously supplied 60 °C figure to maintain product accuracy.

Key Features

• Precise electronic temperature control: Temperature sensors and microcontroller technology help maintain the selected outlet temperature.
• 8 kW rated output: The DHC 8 EC (IN) is designed for applications requiring an 8 kW instantaneous water heating output.
• Three-stage temperature selection: Select from 40 °C, 50 °C or 55 °C according to the current manufacturer specification.
• Suitable for multiple draw-off points: The manufacturer specifies sufficient hot water capability for multiple draw-off points.
• Corrosion-resistant copper heating element and tank: The unit incorporates a copper heating element and tank.
• Adjustable flow limiter: A manually adjustable flow limiter in the cold-water inlet can help optimise water flow and energy consumption.
• Concealed water connection option: Water connections can optionally be routed through the back panel for a cleaner installation where suitable.
• ELCB protection: An Earth Leakage Circuit Breaker provides additional protection against electric shock.
• IP25 protection: The manufacturer specifies IP25 protection for the appliance.
• Compact construction: The appliance measures approximately 360 mm high, 200 mm wide and 110 mm deep, with a listed weight of approximately 2 kg.

How the DHC 8 EC (IN) Works

The DHC 8 EC (IN) works as an instantaneous water heater. When hot water is required, water passes through the appliance and is heated electrically rather than being held in a conventional large storage tank.

Its electronic control system continuously monitors the water temperature using sensors. The microcontroller then regulates operation to help deliver water at the selected temperature. This electronic approach is particularly useful when consistent temperature control is an important part of the installation.

The rotary temperature selector provides three temperature choices. The current STIEBEL ELTRON India specification lists these settings as 40 °C, 50 °C and 55 °C.

Technical Specifications

Applications

The Stiebel Eltron DHC 8 EC (IN) can be considered for suitable residential hot-water applications where an instantaneous electric water heater is preferred. The manufacturer describes the unit as suitable for multiple draw-off points, making it relevant for installations where hot water may be required at more than one outlet.

• Bathrooms and shower applications
• Washbasin hot-water supply
• Residential hot-water installations
• Suitable multi-point hot-water applications
• Installations where compact instantaneous heating is preferred

The actual suitability of the appliance depends on the electrical supply, water pressure, required flow rate, installation conditions and local regulations. A qualified installer should assess the installation before commissioning.

Installation and Safety Information

Installation of an 8 kW tankless electric water heater requires appropriate electrical and plumbing arrangements. STIEBEL ELTRON advises customers to consult their local power supply utility or a registered electrician for appliances that are not supplied ready to plug in.

Electrical protection and correct earthing are particularly important with instantaneous electric water heaters. The DHC 8 EC (IN) incorporates an ELCB for additional protection against electric shock, but the appliance must still be installed correctly according to applicable electrical and plumbing requirements.

Do not attempt electrical installation or modification without appropriate professional qualifications. The required electrical protection, cable sizing, isolating arrangements and installation method should be determined by a qualified electrician based on the appliance specification and the local installation conditions.

Before installation, verify the available electrical supply, water connections, water pressure, installation location and clearances against the current manufacturer’s installation documentation.

Why Choose the DHC 8 EC (IN)?

The DHC 8 EC (IN) combines compact construction with electronic temperature control and an 8 kW heating output. Its sensor-based control system is designed to help maintain a stable outlet temperature, while the three-stage temperature selector makes everyday operation straightforward.

The copper heating element and tank, adjustable flow limiter, concealed water connection option and ELCB protection add practical features for suitable residential installations. With a compact footprint of approximately 360 × 200 × 110 mm, the unit can also be considered where installation space is limited.
