A heating system for heating a confined area with an open-hearth wood-burning fireplace. A fireplace jacket is provided which comprises a multi-chambered double-walled arrangement or a grate member. Log supporting portions of the jacket slant upward slightly in order to prevent a pinging sound by creating convectional force when water is circulating therethrough. The grate member includes first and second headers formed from prisms with triangular bases, and water conducting pipe portions extending on three sides of a fire burning in the open-hearth fireplace. The fireplace jacket is readily utilizable with a conventional forced-air furnace in association with a heat exchanger disposed in the furnace cold air return. Combustion air for the fire is provided from an area external of the confined area to be heated by the heating system.
