The Harvia WL110 protective bedding is made of aluminium-zinc-coated steel that is painted black. WL110 is designed for wood burning heaters with a water tank and other large wood burning heaters, such as the Harvia 36 model.
The protective bedding is used when, for example, the fireplace or wood burning heater is installed onto a waterProofed tile floor. If the fireplace or wood burning heater is installed onto a wooden floor with the protective bedding, a protective sheath must be used as well.
