Slave heater aka. parallel heater

When several heaters need to be controlled with the same thermostat or external heat control system, Warmos Weli parallel heaters are the ones you need.

Oil-filled Warmos Weli parallel heaters are made from Walo, Warma and Wahva series (as 20, 40 and 60 cm high). The installation of parallel heaters is straightforward and the set can be controlled easily. In this case, all radiators are controlled by a master thermostat. The parallel heaters are powder-coated white, other colours are available on request.
