Heat Saver is an essential part of the modem Heating Equipment PUT into your new home as fine a boiler as you please-and the newest and best radiators. If you stop there the heating equipment is not com plete. The boiler makes heat-lots of it, perhaps, and economically. The radiators putit into the rooms. But a third or more of it leaks out through the walls and roof. Costs you money. Does you no good. The modem complete heating system does not waste heat in this way. To the boiler and radia tors it adds the final essential-the Balsam-Wool Blanket which saves the heat-keeps it indoors. And such a modern complete heating system costs little or nothing extra. A smaller boiler is required. Fewer or smaller radiators. The saving pays all or at least a large part of the cost of the Balsam WoolPBlanket. Balsam-Wool is thick-you can get it in the rec ommended full inch thickness as well as the half inch. It is flexible. It tucks in-between the rafters, around doors and windows. It does the job thoroughly-stops heat as no thin, rigid "in sulating board" can do it. Balsam-Wool is sold through retail lumber deal ers. You should know more about it.
