Bus heaters



  • The small number of components makes the Hydronic long-lasting, maintenance-free and service-friendly
  • The flame monitor ensures that the flame is detected with a very high degree of reliability.
  • The intelligent temperature difference evaluation of the two sensors allows the early identification of excessively low water flow rates
  • The low voltage monitor prevents the battery from discharging.
  • Both temperature sensors are placed in waterproof sleeves and are therefore not positioned directly in the water circuit.
  • Due to the rotatable air scoop, combustion air can also be aspirated externally, which allows the system to be ideally adapted to the installation situation
