The Harvia WL550 protective sheath is designed and approved for wood-heated Harvia wood burning heaters (Harvia 20 Pro/SL/Duo, 20 Boiler/20 SL Boiler). The protective sheath considerably reduces the safety distance to combustible materials – in practice, this makes the wood burning heater fit in a smaller space. The protective sheath is attached to the wood burning heater and conforms to the shape of the wood burning heater, making the combination sleek.
