Stainless steel heat exchanger - AFUE - Heating

THE reference in condensing gas heat exchangers for domestic applications

Isothermic® is a stainless steel heat exchanger equipped with the exclusive Sermeta technology: hydroforming. This innovation facilitates flue gas circulation and heat transfer. It is intended for the domestic heating and combi boilers.

Regarding the AFUE “Annual Fuel Utilization Efficiency”, 95% of the energy in the fuel is transferred to heat. In addition to its AFUE rate, Isothermic® has an amazing energy efficiency that reaches up 98%. This innovative product permits to reduce pollutants emissions up to 25% compared to non condensing products.

The Isothermic® casing is made of a double structure cover, built in stainless steel and composite, this conception guarantees minimal heat losses.

Isothermic® is the worldwide bestseller heat exchanger for heating and combi boilers.

Product benefits +
Ease of maintenance
By removing only a few nuts, full access to the combustion chamber is easy at any time.
Low fume pressure losses
The uniform space between the water tubes ensured by hydroforming allows low fume pressure losses.
The Isothermic® coating is made of double structure in composite and stainless steel. The composite material choice offers lightweight and constant quality.
The Sermeta Signature
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.
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
Sermeta heat exchangers and their burners reduce CO2 emission by -25%. CO2 and NOx emissions from our heat exchangers are below regulatory requirements.
    Thanks to our 28 million heat exchangers on the market, the release of 52 million pounds of CO2is avoided every year, thus protecting our environment.
The quality is at the core of our manufacturing processes: 100% of our products are tested on the production line, that is 2.6 million of heat exchangers each year.
    Our 28 million heat exchangers worldwide in use demonstrate our products reliability and the customer service quality that we offer to our clients.
