TESY IWH 50 X02 KI Instant Water Heater

Product detailed description

This compact low-pressure instant water heater is intended for installation above a sink at a single point of use. It is particularly suited for small kitchens, utility rooms, and locations where central hot water systems are not available. The unit is designed for direct connection to a dedicated faucet and requires no additional tank or storage system. Its low-profile dimensions make it ideal for tight spaces while still delivering sufficient hot water for basic domestic needs such as hand washing or small-scale dishwashing.

Installers often encounter this type of unit in residential properties, especially in renovations or extensions where space is limited. The heater integrates directly into the electrical and plumbing systems and is typically used in conjunction with a standard tap. The absence of pressure requirements simplifies installation compared to pressurised systems, though attention must be paid to correct wiring and secure mounting to ensure safety and performance.

Technical parameters

Installation and connection

Installation should be carried out by a qualified electrician and plumber. Begin by ensuring the electrical circuit is rated for at least 25 A and protected by a suitable fuse. Connect the unit using the included mounting kit to a stable surface above the sink. The inlet and outlet connections are compatible with standard plumbing fittings, and the supplied faucet must be used for proper operation.

• Verify that the electrical supply meets the 230 V requirement and is correctly isolated.
• Mount the unit securely using the provided bracket to prevent vibration or movement during operation.
• Ensure the water supply is free of debris and does not exceed the maximum allowable pressure for low-pressure systems.
• Avoid bending or kinking the power cord during installation to prevent damage.

Common mistakes include incorrect electrical wiring, failure to use the supplied faucet, and inadequate mounting support. These can lead to reduced performance, safety hazards, or premature component failure.

Compatibility and accessories

The TESY IWH 50 X02 KI is specifically designed to work with the included faucet and cannot be used with alternative taps. It is suitable for integration into low-pressure domestic water systems and requires no additional accessories for basic operation. The unit is compatible with standard electrical circuits and mounting surfaces typical of kitchen or utility room installations.

Technical background for designers

The heater operates by passing cold water through an internal heating element, which is powered by a 230 V supply. The low-pressure design means it functions effectively without the need for a pump or pressurised system, making it suitable for gravity-fed or low-flow environments. The IP24 rating ensures resistance to splashing water, which is essential for installations near sinks or basins. The unit’s compact size and lightweight construction (0.75 kg) allow for easy integration into tight spaces without requiring structural modifications.

Material durability and thermal efficiency are critical to the unit’s long-term performance. The internal components are designed to withstand repeated thermal cycling and resist corrosion from water exposure. For optimal service life, ensure that the water supply is clean and free from excessive mineral content, which can affect heating element efficiency over time.

Service and operation

No scheduled maintenance is required for the TESY IWH 50 X02 KI, but periodic visual inspections are recommended to check for signs of wear, leakage, or electrical faults. Ensure the power cord remains intact and undamaged, and verify that the mounting bracket remains secure. If the unit fails to heat water or shows signs of overheating, disconnect the power immediately and inspect for blockages or electrical issues.

Frequently asked questions

Can the TESY IWH 50 X02 KI be connected to a standard kitchen sink?
Yes, the unit is specifically designed for use with the supplied faucet and is suitable for installation above a standard kitchen sink.

Does the heater require a separate electrical circuit?
It should be connected to a dedicated 230 V circuit with a 25 A fuse to ensure safe and reliable operation.

Is the unit suitable for use in bathrooms?
Yes, provided the installation site is dry and the IP24-rated enclosure is maintained. Avoid direct exposure to high humidity or standing water.

What is the maximum water temperature it can deliver?
The maximum output temperature depends on the incoming water temperature and the unit’s heating capacity. The 2.9 L/min flow rate assumes a 25°C temperature rise from the cold supply.
