A combined grate and hot water heater for a fireplace which can be easily fabricated using conventional parts, easily installed and easily used is disclosed. The combined grate and hot water heater includes a rectangular shaped cradle for holding combustible materials to be burned which is sized and configured to fit into the fire chamber of the fireplace and a set of supporting legs for supporting the cradle on the floor of the fire chamber in spaced apart relationship. The cradle is made of a plurality of longitudinally extending and laterally extending heavy duty cast iron pipes interconnected by suitable pipe couplings so as to be in fluid communication with one another. A water inlet pipe and a water outlet pipe are connected to and in fluid communication with the pipes in the cradle for supplying water to be heated into the pipes and then allowing exit of the water after it has circulated through the pipes and has been heated by the fire produced on burning of the combustible materials. An inverted U shaped pipe section also made of heavy duty cast iron is coupled in fluid communication with the pipes in the cradle and extends vertically upward into the flue of the fireplace to utilize the heat present in the flue to further heat the water circulated through the pipes.
