BEROA BOILER

The HTW Beroa boiler achieves high levels of performance while achieving high savings in gas consumption, thanks to the condensing technology and its class A energy classification.

Beroa's most important priority is the safety of the user and the boiler itself. That is why it incorporates different protection systems to avoid or minimize possible damage as much as possible.

Main characteristics:

  • Its low gas consumption derives in low emission levels, thus complying with the European ErP Regulation.
  • Its condensing technology reduces the emission of polluting gases, making it sustainable and environmentally friendly.
  • Its stainless steel heat exchanger prevents corrosion and extends the useful life of the boiler.
  • It has a modulating DC fan that adapts to the user's demand, providing great energy savings.
  • With Open-Therm Protocol: a modulating system that communicates the boiler with an Open-Therm thermostat and allows a progressive increase in temperature, avoiding temperature peaks and consumption, reducing electricity consumption and improving the feeling of comfort.
  • Different protection systems: against pump and 3-way valve blockage, against freezing, 3-way safety valve and against gas evacuation problems.
  • Energy classification A.

Available powers: 24 kW - 28 kW - 35 kW
