DUO STORAGE

Unmatched efficiency for Domestic Hot Water

The DUO Storage is a dual heating unit that reaches high capacities in a small space of up to 250 kW. It is mainly intended for commercial applications.

The separation of the combustion chamber and the condensing chamber achieves optimum compactness and maximum efficiency. Its low thermal inertia allows a rapid rise in temperature and limits losses at shutdown.

The Duo Storage complies with the health regulations in force. It shows a 109% efficiency on the high heating value (PCS), and low NOx emissions.

Product benefits +
Ease of maintenance
By removing only a few nuts, full access to the combustion chamber is easy at any time.
Direct hot water use
Perfectly suited for hot water applications, stainless steel can be in direct contact with the drinking water circuit.
Comfort
The DUO Storage allows almost unlimited hot water on tap, ensuring great comfort for the user
Fast response time
The low water content of the coils allows minimal thermal inertia.
    The heat exchanger performance also ensures almost immediate regeneration of the hot water tank.
The Sermeta Signature
Reliability
To ensure an unrivalled reliability, we develop our products and their manufacturing processes in parallel.
    Our expertise allows us to internally develop automated, productive and innovative production lines. The automation ensures a consistent quality.
Longevity
Hydroforming is a proprietary industrial process that ensures a uniform and consistent gap between the stainless steel tubes. This facilitates the fumes circulation and heat transmission as well as natural cleaning process.
    Stainless steel is a material perfectly adapted to the condensation conditions. It offers many qualities:
  • Reliability
  • Robustness
  • Resistance to thermal shocks
  • Low thermal inertia
  • Long life
  • Low sensitivity to the pH of water
