PERFORMANCE

Tests accomplished by the independent certification body KIWA Nederland BV confirm the optimal performance of the ZYPHO 8kW double-walled V2.

The values​​ to the right were obtained under the following conditions:

Cold mains water: 10°C
Shower water: 40°C

INSTALLATION

The ZYPHO can be installed in two ways:

a) Coupled to the shower tray.

installation_a

b) Placed under the shower tray or bathtub with desired separation.

installation_b

Cold mains water is connected to the ZYPHO inlet.
Preheated water exiting the ZYPHO can be connected in one of the three following configurations:

a) To the shower mixing faucet (cold mains water) and to the domestic water heater inlet. This configuration provides a maximum of recovered energy.

configuration_a

b) To the shower mixing faucet (cold mains water) only. We recommend this configuration if the water heating device is located far or if connection to it is unreasonably difficult.

configuration_b

c) To the water heater inlet only.

APPLICATIONS

The ZYPHO is a versatile system which thanks to its unique design can be adopted in various situations, for example:
  • Domestic bathrooms;
  • Hotels;
  • Campsites;
  • Bungalows;
  • Swimming pools & Spas;
  • Gyms;
  • Sports facilities;
  • Factories.

MAINTENANCE

The ZYPHO has been designed to require minimal maintenance other than usual cleaning with traps and filters retaining almost all hair and dirt, thus preventing blockages.

To avoid losing efficiency in the long term, we recommend to periodically dissolve soap residue on the copper pipe of the ZYPHO.
