The ideal solution for modern living: The ETG500

The Heliotherm ETG500 storage buffer offers state-of-the-art technology and innovative functions that provide maximum convenience and energy efficiency. Thanks to the advanced plug-and-function technology, the storage buffer is ready for use immediately after installation. This sophisticated technology saves time and effort during commissioning and makes the system particularly user-friendly.

The most important advantages at a glance:

• Hygienic hot water preparation: the integrated fresh hot water system heats the water as required, enabling unnecessary energy consumption to be avoided. A stainless steel plate heat exchanger ensures efficient and hygienic heating and offers reliable protection against legionella thanks to the counterflow principle.
• Wide range of applications: The ETG500 combines the functions of heating and cooling (up to 7 °C) with constant hot water preparation. An intelligent solution that combines convenience and functionality in one appliance.
• Compact and space-saving design: Thanks to the integrated hydraulic station and compact design, the ETG500 is also suitable for confined spaces. Assembly time is reduced by up to 70 %, saving time and costs.
• Intelligent control technology: The dual-core touch display offers a user-friendly interface and enables intuitive operation. Remote maintenance, PV integration and Modbus control maximise self-consumption of solar power and increase energy efficiency.
• Efficient operation: The Heliotherm stratified charging system ensures even energy distribution and minimises consumption costs. The low-maintenance design guarantees quick and easy maintenance.
• Protection and comfort: The innovative Heliotherm PBS® (Passive Balancing System) minimises energy losses and optimises efficiency. Additional functions such as anti-scale technology and an integrated emergency heating system offer safety and extend the service life.

The Heliotherm ETG500 is a future-orientated solution that impresses with its user-friendliness, energy efficiency and durability. With its high efficiency and low operating costs, the system makes a decisive contribution to sustainable energy savings. Another advantage: no special refrigeration licence is required for installation and operation.

This combination of state-of-the-art technology, simple operation and sustainable energy savings makes the ETG500 the ideal choice for anyone looking for a powerful and reliable heating and cooling system.

The most natural heat pump in the world

Utilise the inexhaustible source of energy directly under your feet: geothermal energy. Heliotherm's Natural Technology direct evaporation heat pump enables you to extract this energy more efficiently and in a more environmentally friendly way than ever before. Thanks to state-of-the-art, highly efficient heat pump technology, you can achieve an impressive annual coefficient of performance (COP) of 6.7, which means that you can generate 6.7 kW of heating power with just 1 kW of electricity - an unbeatable energy balance!

But that's not all. With the Natural Technology heat pump, you benefit from a heat pump of the latest generation, which offers you more comfort, more efficiency and more sustainability. Unlike conventional heat pumps, Natural Technology works without synthetic refrigerants or fluorinated greenhouse gases. Instead, it uses propane, a particularly efficient and climate-friendly refrigerant. It is also 100 per cent harmless to soil and groundwater, making it the perfect choice for water protection areas.

Another plus: the heat pump is installed outdoors, enabling the living space to remain completely intact. It is also PV-compatible, enabling you to seamlessly combine your heat pump with a photovoltaic system. Use your self-generated solar power to further reduce your heating costs!
