ELÍZ PET 3 kW

Product detailed description

This immersion heater is designed for integration into ELÍZ stationary solar water heating systems. It is typically installed in residential and commercial buildings where solar thermal systems require additional electrical heating support. The unit fits into a dedicated G 6/4” threaded opening located centrally within the water tank. It operates as a supplementary heat source when solar input is insufficient, ensuring continuous hot water supply.

The heater is specifically suited for ELÍZ water tanks with capacities between 200–500 litres. It is commonly used in hybrid systems where solar energy is the primary source and electrical heating serves as backup. The inclusion of a power cable with a 230 V plug simplifies connection to standard electrical supplies. Installers should ensure the system is compatible with the tank’s design and that all electrical connections are made in accordance with local regulations.

Technical parameters

Code	ELZ_3341
Brand	ELIZ

The nominal power of 3000 W determines the rate at which the heater can raise the temperature of stored water. The G 6/4” thread size ensures compatibility with specific ELIZ water heater models. The presence of a built-in thermostat allows for temperature regulation without requiring external controls. These parameters are essential for correct sizing and system performance.Installation and connection The heater is inserted through the central opening in the water tank and secured using the G 6/4” thread. The power cable must be routed externally to a suitable electrical junction box. Installers should verify that the tank has a dedicated opening of the correct size and that the internal space allows for secure fitting. Common mistakes include incorrect thread alignment, failure to seal the connection properly, and improper routing of the power cable, which can lead to leaks or electrical hazards. Always ensure the tank is empty during installation and that the system is depressurised.Compatibility and accessories This heater is specifically designed for ELÍZ stationary water heaters with a 200–500 litre capacity and a G 6/4” threaded opening. It is not interchangeable with other brands or models without verification. The heater includes a power cable with a 230 V plug, eliminating the need for additional wiring components. No further accessories are required for standard installation. Ensure the tank model matches the specifications provided by the manufacturer.Technical background for designers The heater operates via direct immersion in water, using resistance heating to generate thermal energy. The stainless steel construction provides resistance to corrosion and prolongs service life in contact with water. The built-in thermostat regulates temperature by switching the heating element on and off based on the setpoint. Integration into the system depends on the tank’s internal design and the positioning of the opening. Efficiency is influenced by the volume of water, ambient temperature, and the frequency of use. Proper insulation of the tank and piping enhances overall system performance.Service and operation Routine checks should include verifying the integrity of the thread seal, inspecting the power cable for wear or damage, and confirming that the thermostat functions correctly. There are no specified service intervals in the provided documentation. Any signs of leakage or irregular operation should be investigated immediately. The unit requires no scheduled maintenance beyond these basic checks. In case of failure, the entire unit must be removed and replaced, as it is not designed for disassembly.Frequently asked questions
