The Roxell Siroc Turbo cannon heater runs on gas or oil. Siroc Turbo is 100 % efficient due to the open combustion that keeps all the heat generated indoors. The energy performance of the Siroc Turbo is therefore very high. LED lights indicate the status and defects, so you can identify the cause of a problem immediately. Roxell has given this basic appliance a wide set of features that ensure a reliable performance.
