Innovative recovery of shower heat

ZYPHO® - the innovative recovery of shower heat

ZYPHO is a compact and highly efficient heat exchanger that is installed under the shower tray. It absorbs the heat energy from the drainage water and uses it to preheat the cold water, reducing energy consumption by 30%.

Warm shower water flows unused into the canal

Every day, enormous amounts of energy in the form of warm shower wastewater flow unused into the sewer. For example, an average household uses around 200 liters of hot water at 38 ° C per day, the energy potential of which has not been efficiently utilized until today. From a technical point of view, the recovery of heat from wastewater by means of heat exchangers is well-known, with the ZYPHO this know-how is being efficiently implemented in the shower area for the first time.

The solution - ZYPHO®

Depending on the desired shower temperature, the mixing valve in the shower mixes cold with warm fresh water. In the ZYPHO, the cold fresh water is preheated by the warm shower waste water and thus comes at an already higher temperature of approx. 24 °C in the mixing valve. This results in many advantages for you.

  • Strong reduction of the required amount of additional hot water to achieve the desired temperature.
  • Annual cost savings of around € 200 (avg. Austrian household with 4 persons).
  • Thus, the issue pays for itself in just 2 years.
  • You make an important contribution to the protection of the environment and the conscious use of our energy resources

Technical specifications

ZYPHO is a waste water heat exchanger and with its compact design, which is specially designed for showers, it can easily be installed under every shower tray.

Hygiene and safety

ZYPHO complies with the strictest hygiene regulations. The wastewater is double-walled according to EN 1717 and therefore never in direct contact with the clean shower water. Legionella pose no danger because the warm waste water never stagnates due to the internal gradient of 2% and the corpus cools down to below 25 ° C in the resting phase (according to WHO recommendation). In addition, the copper tubes used also contribute to the prophylaxis of Legionella.

  • Certified to EN1717 (sections 5.2 and – TÜV Rheinland
  • kiwa efficiency certificate according to NEN7120: 2011 / C2: 2011

Area of applications

The higher the hot water consumption, the faster the heat recovery pays off. Therefore, the ZYPHO is especially suitable for the following applications:

  • Private bathroom
