The OCE european-style convector comes in three different heights. Furthermore, the OCEH, OCEM and OCEB provide power ranging from 500W to 3000W. The OCE can be equipped with a built-in electronic thermostat (TH) or teamed with a wall-mounted electronic thermostat (OTH). When combined with the wall-mounted thermostat, the convector may be installed on an exterior wall. The OCE and its thermostats provide an ingenious heating system that maximizes both comfort and energy efficiency.
