Design with upper outlet:

  • Indirect heaters with volumes between 100–160 litres with enamelled vessel and high performance heat exchanger designed to be placed on the floor under the suspended gas boiler.
  • All outlets including the outlets of the heat exchanger are directed upwards for easier connection with the suspended gas boiler.

Most common use

  • Preparation of hot water in premisses equipped with gas boilers.
