How to modernize a heating system effectively?

Small buildings, big challenge: how to modernize a heating system effectively?

HEATER CONDENS water unit heaters are designed specifically for projects like these:

  • - Low supply temperatures – energy savings when used with heat pumps and condensing boilers
  • - Intelligent power modulation – EC motors adjust output to actual heating demand
  • - Compatibility with all heat sources – from heat pumps and condensing boilers to traditional coal-fired boilers
  • - Fast and easy installation – simple wall or ceiling mounting
  • - Wide output range – 10–120 kW for precise sizing across different building volumes
  • - Mobile app control – remote temperature control and adjustment via smartphone
