<p>A grate 10 of interconnected hollow members is arranged at the base of the fireplace and is connected at its rear to a hollow main panel 12 having a sloping upper part 13. Water circulates in the grate 10 and panel 12 and absorbs heat when there is a fire in the grate, the efficiency of heat absorption being enhanced by the saw-toothed profile of the front surface of the panel 12. Heat not absorbed by the panel 12 is diverted by the sloping part 13 and impinges on the lower surface of a tank 14 which contains water and is arranged horizontally directly above the grate 10. Heat and flames ascending vertically from the grate 10 also impinge on the lower surface of the tank 14 which has a cross-section in the form of an inverted triangle and lower sides with saw-toothed profile again to enhance heat absorption. <IMAGE></p> |
