Abstract
Abstract A heat storage vault in the form of an insulated enclosure having therein a plurality of serpentine pipes each with lengths extending back and forth within the enclosure with the lengths substantially equidistantly spaced both from the closest lengths of the common serpentine pipe and from the closest lengths of the other adjacent pipes, and a heat storage medium filling the enclosure and the space between the serpentine pipes and adapted to receive heat from at least one of the serpentine pipes when a heated fluid is conducted therethrough, store the heat within the heat storage medium, and provide heat to at least one other of the serpentine pipes as a fluid is circulated therethrough.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
125 words
A heat storage vault, comprising: an insulated enclosure of fixed dimensions; a plurality of independent, serpentine pipes each being isolated from the other serpentine pipes and each having substantially linear lengths extending back and forth within the enclosure with the lengths thereof substantially equidistantly spaced both from the closest length of the same pipe and equidistantly spaced from each closest length of each of the other independent serpentine pipes; and a heat storage medium filling the enclosure and the space between the serpentine pipe lengths; whereby substantial amounts of heat energy may be invested in the heat storage medium by one of the serpentine pipes and heat energy may be withdrawn from the heat storage medium by at least one other of the serpentine pipes.
Claim 2
Dependent Claim
125 words
A heat storage vault, comprising: an insulated enclosure of fixed dimensions; a plurality of independent, serpentine pipes each being isolated from the other serpentine pipes and each having substantially linear lengths extending back and forth within the enclosure with the lengths thereof substantially equidistantly spaced both from the closest length of the same pipe and equidistantly spaced from each closest length of each of the other independent serpentine pipes; and a heat storage medium filling the enclosure and the space between the serpentine pipe lengths; whereby substantial amounts of heat energy may be invested in the heat storage medium by one of the serpentine pipes and heat energy may be withdrawn from the heat storage medium by at least one other of the serpentine pipes.
Claim 3
Dependent Claim
31 words
A heat storage vault as set forth in claim 1 in which at least one of the serpentine pipes is connected to a substantially closed loop with a heat energy source.
Claim 4
Dependent Claim
26 words
A heat storage vault as set forth in claim 1 in which at least one of the serpentine pipes is connected to a solar energy collector.
