As the Harvia protective sheaths are wood burning heater model-specific, no compromises have been made in terms of design or performance. The protective sheath is available both as a full version and as a one-sided sheath, which can be installed on either side of the wood burning heater. The protective sheaths are made of steel sheet that is painted black. If you also need to protect your floor, the black WL100 protective bedding matches the style.
