Abstract: A heating system and method includes a water circulation system for heating the interior of a building. The system further includes a boiler for storing and alternatively heating the water, and a fireplace jacket positioned in a fireplace of the building. The fireplace jacket includes a serpentine shaped length of pipe for circulating water. Fireplace jacket inlet and outlet ports communicate with the boiler for circulating the water in a closed system. A heating system control system manages the circulation of the water in the circulation system. The control system includes a safety unit having a thermometer, and the control system automatically circulates the water when the water is heated to a specified temperature. The control system automatically switches between using fossil fuel to heat the water in the boiler and using the fireplace jacket to heat the water in the boiler.

Abstract: A portable multi-purpose outdoor fire container and hot water storage system comprising a first container of a cylindrical configuration with an open bottom surface and an open top surface with a cylindrical side wall therebetween is disclosed. The container has a grate supported by the opened top surface with the bottom surface capable of supporting firewood thereon. The container also has an air vent with handles in the side wall selectively openable in the sidewall at an intermediate extent thereof. A second hot water storage container in a box-like configuration is provided with rectangular sidewalls, a closed bottom and an open top with a lid positionable to close the open top. The hot water storage container is water impermeable for the storage of hot water therein.

Abstract: A low profile, high efficiency, fireplace boiler wherein a burner tray supports a number of gas fired burners and artificial logs within a hearth area of the firebox and about which logs the gas and flames are distributed. Combustion air is drawn from a conduit that surrounds an exhaust conduit at a chimney and circulated via a distributing manifold to the space beneath the burner tray, where it mixes with the fuel. Additional secondary air is directed from ports at intersecting levels of the tray to create flickering. Heated exhaust gasses are directed by a baffle to contact exposed walls of a liquid filled heat exchanger formed into the top and rear walls of the firebox and to pass through the bottoms of a number of vertical plenums mounted within the heat exchanger behind the baffle. A spring biased explosion door is provided beneath the burner tray. Liquid is circulated through the heat exchanger to distribution conduits arrayed about the premises.

Abstract: A direct vent gas fireplace is provided with a heat shield forming a combustion air expansion and distribution chamber covering a substantial portion of the upper surface of the firebox enclosure and having a circular combustion air inlet opening in its upper surface and being in communication with the lower portion of the firebox, and the products of combustion from the firebox are directed out of the fireplace through a pipe extending through the upper enclosure surface and out through the combustion air inlet opening in the heat shield with the axis of the pipe being offset from the center of the inlet opening so that when a combustion air inlet duct is sleeved over the pipe and connected to the inlet opening a portion of the combustion air path between the pipe and duct which feeds into the combustion air expansion and distribution chamber is substantially widened to provide space for the combustion air to expand outwardly rather than backing up the combustion air duct.

Abstract: In a method for manufacture and mounting of fire-places, e.g. stoves, a lower and an upper half of the fire-place are manufactured separately and transported to the mounting place. The lower half is positioned and subsequently the upper half is lifted by means of a wheel-supported lifting frame, adjusted into its correct position and fastened by means of mortar to said lower half, whereupon connection to a smoke flue and a chimney is made. A device for mounting fire-places, e.g. stoves, comprises a wheel-supported lifting frame having a unit for lifting prefabricated fire-place halves to which lifting means are attached. The frame has such dimensions that lifting a distance corresponding at least to the height of said lower fire-place half is possible.

Abstract: A hearth having an air supply through the bottom, a metal dish arranged at a predetermined height above the bottom and defining an area for preheating combustion air which then flows upwardly around the contour of the dish to form a curtain of preheated air. A belt may be provided surrounding the dish which defines an air inlet slot. The method comprises introducing combustion air into the hearth in the form of a continuous stream to form a continuous ascending air curtain laterally surrounding glowing embers in the hearth. Water or water vapor may be introduced into a zone having a temperauture high enough to decompose the water molecules, thereby locally activating combustion.

Abstract: A solid fuel combustion chamber combusts the fuel utilizing underfire and overfire air. Both the underfire and overfire air derive from a common intake port, with a controllable vane determining the ratio between the two air sources. Gas flow from the solid fuel combustion chamber enters a gas combustion chamber designed to produce turbulence and thereby promote further combustion. The gas flow is then accelerated in a gas flow chamber and directed to the circulating fluid carrying tubes of a heat exchanger. The heat exchanger includes a condensation chamber which extracts sufficient heat from the gas flow to produce a condensate. An injection system superheats the condensate and injects it into the solid fuel combustion chamber to thereby reduce residue accumulation.
