HPH Hygienic — hygienic flow buffer tanks

The buffer tanks of the HPH Hygienic series have been designed for efficient and hygienic domestic hot water preparation in flow mode. The product uses the accumulated thermal energy from the heating system and transfers it directly to the domestic water through an integrated large-surface heat exchanger. As a result, the water is heated quickly and only at the moment of consumption — minimizing energy losses and making the solution particularly advantageous in low-temperature heating systems (e.g., heat pumps).

Hygienic water preparation

The heat exchanger is made of corrugated stainless steel tube AISI-316L, a material with high corrosion resistance and hygienic properties. The design of the exchanger limits the risk of bacterial growth (including Legionella), so the tank does not require elevated disinfection temperatures. This allows economical and safe preparation of hot water without the need for periodic heating to very high temperatures.

Applications and functions

HPH Hygienic tanks can work as a separating element of glycol–water circuits, as well as for connecting two heat sources operating at different working pressures. Thanks to their durable, maintenance-free design, the devices do not require annual maintenance or magnesium anode replacement — reducing operating costs compared to traditional enamelled water heaters.

Key advantages

• Flow heating — hot water only at the time of consumption.
• Heat exchanger made of AISI-316L stainless steel — high hygiene and corrosion resistance.
• Reduced Legionella risk — no need for high-temperature disinfection.
• Compatibility with low-temperature installations (e.g., heat pumps).
• Possibility to separate glycol–water circuits and connect sources with different pressures.
• Maintenance-free operation — no annual magnesium anode inspection.
• Longer service life than traditional enamelled heaters.

Typical applications

• Residential and multi-family buildings.
• Public utility and commercial facilities.
• Installations with heat pumps and low-temperature sources.
• Systems requiring separation of the heating medium (glycol–water).

The use of an HPH Hygienic tank is a choice of an energy-efficient solution, safe for users’ health, and requiring minimal maintenance. It is a modern alternative to classic enamelled water heaters.
