High-efficiency and independent gas fired convectors for every kind of environment.

Instant heating where you need it and when you need it: Calorio is an independent and modular system that allows different rooms to be heated to different temperatures, optimizing the heating by autonomously regulating the temperature of each single zone. Calorio adjusts therefore fuel consumption to actual requirements.

Features and benefits

  • Three minutes is all that it needs for Robur room heaters to warm up a room.
  • 30% savings compared to a central heating system.
  • Quick to install thanks to the easy installation of the support bracket and the position of the gas and electrical connections (external of the cover). Just one 50 mm hole through the wall for a concentric pipe is needed.
  • Supplied as standard with exhaust/intake air concentric pipe, external flue terminal in aluminium alloy, template, wall support bracket, LPG kit.
  • Safe and reliable because the combustion circuit is completely room sealed, and all products of combustion are exhausted outdoors.
