The competitive condensation solution for tankless gas water heaters.

ISO Tankless is a heat exchanger to produce hot water. Its dimensions are adapted to be integrated in compact tankless gas water heater.

ISO Tankless is equipped with Sermeta’s technology, the Bluejet® premix burner. This innovation helps to reduce significantly NOx emissions.

Its high performance and reliable conception benefits from the SERMETA knowledge on gas condensing heat exchangers. The DHW temperature remains stable in any use thanks to a huge gas turndown ratio up to 30:1, which giving a high comfort level.

The use of stainless steel for the design of the ISO tankless guarantees performances over the whole tankless gas water heater product lifetime.

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.
  • Imperceptible water temperature fluctuation during simultaneous use of taps
  • Constant water temperature at the tap, whatever the demand, even for low flow rates.
Fast response time
Hot water is available immediately on tap.
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.
