ELÍZ EWHP 300 EW Water Heating Heat Pump

Product detailed description

Water heating heat pumps are commonly used in residential and commercial buildings to provide hot water efficiently. The ELÍZ EWHP 300 EW is a monoblock unit designed for indoor installation, making it suitable for use in utility rooms, basements, and other enclosed spaces. The system integrates a heat pump with an electric heating element, allowing for flexible operation modes and reliable performance across different ambient conditions. Installers should consider the unit's dimensions and weight when planning the installation location and structural support.

The system operates on the air-to-water principle, extracting heat from the ambient air and transferring it to the water storage tank. The compact design and low noise level of 56 dB(A) make it suitable for use in environments where noise is a concern. The unit is equipped with a digital control system featuring a large touchscreen display, allowing for precise temperature control and monitoring of system performance. The heat pump is compatible with a range of water heating systems and can be integrated into existing plumbing infrastructure with minimal modifications.

Technical parameters

Installation and connection

The installation of the ELÍZ EWHP 300 EW requires careful planning to ensure proper operation and longevity. The unit should be installed in a well-ventilated area with sufficient space for air circulation. The water connections are G3/4", and the electrical connection is 230 V with a 16 A fuse. The IPX4 rating indicates that the unit is protected against splashing water, making it suitable for use in environments with occasional moisture.

During installation, it is important to check the water pressure and ensure that it does not exceed 8 Bar. The maximum refrigerant pressure of 2.6 MPa should also be monitored to prevent system damage. Common installation mistakes include improper ventilation, incorrect electrical connections, and failure to secure the unit properly. The unit's weight of 130 kg requires a stable mounting surface to prevent vibration and noise issues.

Compatibility and accessories

The ELÍZ EWHP 300 EW is compatible with standard plumbing systems and can be integrated into existing hot water infrastructure. The unit is designed to work with a 2000 W electric heating element, which provides additional heating capacity when needed. No additional accessories are required for basic operation, but installers may need to order specific components for custom installations. The unit's digital control system allows for remote monitoring and control via a WiFi connection, which requires a compatible smart device and network setup.

Technical background for designers

The ELÍZ EWHP 300 EW operates on the principle of heat transfer from the ambient air to the water storage tank. The heat pump uses a refrigerant cycle to extract heat from the air and transfer it to the water. The refrigerant R134A is chosen for its low environmental impact and efficient heat transfer properties. The condenser heat exchanger is made of aluminum, which provides a large surface area for heat transfer and ensures efficient operation.

The system's design includes a digital control unit with a touchscreen display, which allows for precise temperature control and monitoring of system performance. The control system supports multiple operating modes, including automatic, eco, and fast heating. The integration of the heat pump with an electric heating element provides flexibility in operation and ensures that the system can meet varying hot water demands. The unit's insulation is made of polyurethane without CFC, which minimizes heat loss and improves overall efficiency.

Service and operation

Regular maintenance is essential to ensure the long-term performance and efficiency of the ELÍZ EWHP 300 EW. The unit should be inspected periodically for signs of wear, leaks, and electrical issues. The water tank is made of high-quality steel with a zirconium glaze coating, which provides protection against corrosion. The insulation layer is 50 mm thick and made of polyurethane, which helps to reduce heat loss and maintain water temperature.

During operation, the system should be monitored for temperature fluctuations and system errors. The digital control unit displays system status, water temperature, and error messages, which can help in diagnosing issues. The unit includes safety features such as anti-frost protection, overheating protection, and anti-Legionella control. These features help to prevent damage to the system and ensure safe operation. The unit's warranty covers the entire product for 2 years, providing peace of mind for installers and end-users.
