Harvia's published figures. Room volumes are a guide: glass, stone and other heavy or uninsulated surfaces need more output, and we size equipment for the actual room. Electrical supply, protection and installation in Australia are designed and carried out by a licensed electrician to the manufacturer's instructions.
