Abstract
Abstract A water heating system for providing heated water at a constant temperature at all locations of intended use in either closed or non-closed loop type distribution systems. The system employs a jet entrainer as a device for mixing water supplied thereto at different temperatures and maintains the temperature of the mixed water constant regardless of variations in the pressure of the water driving the device or being entrained by the device. The jet entrainer is constructed by providing an appropriate size nozzle, tee-shaped member and mixing chamber. The nozzle is then inserted into one end of the tee-shaped member and joined thereto to form a watertight seal. The mixing chamber is then inserted into the other end of the tee-shaped member and joined thereto to form a watertight seal.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
149 words
A system for supplying heated water at a constant temperature from a source to the inlets of a plurality of fixtures, said system comprising: a. water heater means having an inlet and an outlet, said outlet providing said source of heated water, and b. jet entrainer means having a first and second inlet and an outlet, said first inlet being connected to said outlet of said source of heated water, said second inlet being connected between a nozzle and a source of relatively cold water, and said outlet of said jet entrainer being connected to each of said inlets of said plurality of fixtures, said nozzle being positioned in said entraining means for providing a high velocity stream of water which entrains water from said first inlet in proportion to its velocity to thereby maintain the temperature of the water at said outlet of said entrainer means substantially constant.
Claim 2
Independent Claim
149 words
A system for supplying heated water at a constant temperature from a source to the inlets of a plurality of fixtures, said system comprising: a. water heater means having an inlet and an outlet, said outlet providing said source of heated water, and b. jet entrainer means having a first and second inlet and an outlet, said first inlet being connected to said outlet of said source of heated water, said second inlet being connected between a nozzle and a source of relatively cold water, and said outlet of said jet entrainer being connected to each of said inlets of said plurality of fixtures, said nozzle being positioned in said entraining means for providing a high velocity stream of water which entrains water from said first inlet in proportion to its velocity to thereby maintain the temperature of the water at said outlet of said entrainer means substantially constant.
Claim 3
Independent Claim
149 words
A system for supplying heated water at a constant temperature from a source to the inlets of a plurality of fixtures, said system comprising: a. water heater means having an inlet and an outlet, said outlet providing said source of heated water, and b. jet entrainer means having a first and second inlet and an outlet, said first inlet being connected to said outlet of said source of heated water, said second inlet being connected between a nozzle and a source of relatively cold water, and said outlet of said jet entrainer being connected to each of said inlets of said plurality of fixtures, said nozzle being positioned in said entraining means for providing a high velocity stream of water which entrains water from said first inlet in proportion to its velocity to thereby maintain the temperature of the water at said outlet of said entrainer means substantially constant.
Claim 4
Independent Claim
149 words
A system for supplying heated water at a constant temperature from a source to the inlets of a plurality of fixtures, said system comprising: a. water heater means having an inlet and an outlet, said outlet providing said source of heated water, and b. jet entrainer means having a first and second inlet and an outlet, said first inlet being connected to said outlet of said source of heated water, said second inlet being connected between a nozzle and a source of relatively cold water, and said outlet of said jet entrainer being connected to each of said inlets of said plurality of fixtures, said nozzle being positioned in said entraining means for providing a high velocity stream of water which entrains water from said first inlet in proportion to its velocity to thereby maintain the temperature of the water at said outlet of said entrainer means substantially constant.
Claim 5
Dependent Claim
21 words

Claim 6
Dependent Claim
26 words
The water heating system of claim 1 wherein the outlet of said jet entrainer means is also connected to the inlet of said water heater means.
Claim 7
Dependent Claim
52 words
The water heating system of claim 1 further comprising first balancing valve means connected between said source of cold water and the second inlet of said jet entrainer means and second balancing valve means connected between the outlet of said water heater means and said first inlet of said jet entrainer means.
Claim 8
Dependent Claim
29 words
The water heating system of claim 1 wherein said inlet of the fixture at the location of intended use is connected to the inlet of said water heater means.
Claim 9
Dependent Claim
37 words
The water heating system of claim 1 further comprising mono-flow means connected between the outlet of said jet entrainer means and said fixtures, said mono-flow means being further connected to the inlet of said water heater means.
Claim 10
Dependent Claim
50 words
The water heating system of claim 4 further comprising first check-valve means connected between said source of cold water and the second inlet of said jet entrainer means and second check-valve means connected between the outlet of said water heater means and said first inlet of said jet entrainer means.
Claim 11
Independent Claim
149 words
A system for supplying heated water at a constant temperature from a source to the inlets of a plurality of fixtures, said system comprising: a. water heater means having an inlet and an outlet, said outlet providing said source of heated water, and b. jet entrainer means having a first and second inlet and an outlet, said first inlet being connected between a nozzle and said outlet of said source of heated water, said second inlet being connected to a source of relatively cold water, and said outlet of said jet entrainer being connected to each of said inlets of said plurality of fixtures, said nozzle being positioned in said entraining means for providing a high velocity stream of water which entrains water from said second inlet in proportion to its velocity to thereby maintain the temperature of the water at said outlet of said entrainer means substantially constant.
Claim 12
Independent Claim
149 words
