Claim 1
Independent Claim
354 words
A fireplace heating and cooling system, comprising: a firebox having a mouth for the introduction of fuel and a throat for the exhaustion of combustion gases; a water reservoir mounted on top of said firebox having an external wall through which is mounted a water inlet and a water outlet, and having a central passage formed by an interior wall of said reservoir, communicating with said throat, with first heat exchanging elements mounted on said interior wall within said central passage for absorbing heat from said combustion gases and second heat exchanging elements mounted on said interior wall within said reservoir for transferring said absorbed heat to the water stored in said reservoir; a valve means connected to said water inlet and water outlet, having a first position connecting said water inlet to a pressurized water supply and said water outlet to a hot water outlet; said water reservoir having third heat exchanging elements mounted on the outside surface of the external wall of said reservoir; an air plenum formed around said external wall of said reservoir having an air inlet and an air outlet mounted therein and connected to a space whose temperature is to be maintained, for conducting air across said third heat exchanging elements, to transfer heat between said water and said air; a fourth heat exchanging element connected to a heat sink, through which water is circulated by means of a pump, having a water inlet and a water outlet; said valve means having a second position connecting said water inlet of said water reservoir to said water outlet of said fourth heat exchanging element and connecting said water outlet of said water reservoir to said water inlet of said fourth heat exchanging element; said air being warmed in said plenum for heating said space and said pressurized water being warmed in said reservoir with said valve means in said first position, for supplying hot water, after combustion has occurred in said firebox; said air being cooled in said plenum for cooling said space, with said valve means in said second position, when no combustion has occurred in said firebox.
Claim 2
Dependent Claim
354 words
A fireplace heating and cooling system, comprising: a firebox having a mouth for the introduction of fuel and a throat for the exhaustion of combustion gases; a water reservoir mounted on top of said firebox having an external wall through which is mounted a water inlet and a water outlet, and having a central passage formed by an interior wall of said reservoir, communicating with said throat, with first heat exchanging elements mounted on said interior wall within said central passage for absorbing heat from said combustion gases and second heat exchanging elements mounted on said interior wall within said reservoir for transferring said absorbed heat to the water stored in said reservoir; a valve means connected to said water inlet and water outlet, having a first position connecting said water inlet to a pressurized water supply and said water outlet to a hot water outlet; said water reservoir having third heat exchanging elements mounted on the outside surface of the external wall of said reservoir; an air plenum formed around said external wall of said reservoir having an air inlet and an air outlet mounted therein and connected to a space whose temperature is to be maintained, for conducting air across said third heat exchanging elements, to transfer heat between said water and said air; a fourth heat exchanging element connected to a heat sink, through which water is circulated by means of a pump, having a water inlet and a water outlet; said valve means having a second position connecting said water inlet of said water reservoir to said water outlet of said fourth heat exchanging element and connecting said water outlet of said water reservoir to said water inlet of said fourth heat exchanging element; said air being warmed in said plenum for heating said space and said pressurized water being warmed in said reservoir with said valve means in said first position, for supplying hot water, after combustion has occurred in said firebox; said air being cooled in said plenum for cooling said space, with said valve means in said second position, when no combustion has occurred in said firebox.
Claim 3
Dependent Claim
24 words
The system of claim 1, wherein said air inlet and air outlet of said plenum is connected to a forced air central heating system.
Claim 4
Dependent Claim
65 words
The system of claim 1, which further comprises: a second plenum surrounding said firebox having an air inlet connected to the ambient and an air outlet; an air grate in the mouth of said firebox having an air inlet connected to said air outlet of said firebox plenum and an air outlet connected to the ambient; whereby the air in the ambient may be heated.
Claim 5
Dependent Claim
15 words
The system of claim 1, wherein said hot water is used as hot tap water.
Claim 6
Dependent Claim
18 words
The system of claim 1, wherein said hot water is passed through a radiator to heat the ambient.
Claim 7
Dependent Claim
15 words
The system of claim 1, wherein said heat sink is a bulk of subterranean soil.
Claim 8
Dependent Claim
13 words
The system of claim 1, wherein said heat sink is a water well.
Claim 9
Dependent Claim
40 words
The system of claim 3, wherein said air inlet of said second plenum and said air outlet of said air grate are connected to said plenum formed around said external wall of said reservoir to further heat the air therein.
