The backflow preventer creates an isolated or closed plumbing system. For some homeowners, thermal expansion could produce leaky faucets or set off the relief valve on hot water heaters, or in some cases, other damage may occur. Thermal expansion occurs when your hot water heater heats the water, causing it to expand. In order to control thermal expansion, simply lowering the temperature setting of the hot water tank to 115-125 degrees (which is sufficient for most purposes) might reduce the possibility of thermal expansion. A plumber may recommend the installation of one of the following two types of products to control thermal expansion: Thermal expansion tank on your hot water heater.

modify Gao so that the circuit of Ref. 1 replaces 102 and the 103 of Gao is positioned in place of solar heater 1 of Ref. 1 so that in the combined teachings the outlet of 112 is connected where the outlet of 1 in Ref. 1 is located and the inlet of 111 is connected where the inlet of 1 in Ref. 1 is located and further replace pump 115 of Gao with pump 3 of Ref. 1
A person of ordinary skill in the art prior to the effective filing date of the claimed invention would have been motivated to make the above modification(s) because:
it would allow for Gao to still cool the dielectric fluid and to utilize the heat generated to heat water in a domestic hot water storage tank while preventing over heating of the water in the storage tank and in the liquid cooling chassis as well (Ref. 1, ¶ [0011], The invention offers the advantage that when a preselected temperature is reached, the pump in the cooling line is automatically switched on, thereby cooling the energy converter. This effectively protects the energy converter from high thermal loads.)
Joo teaches of:
a water replenishing kit, configured to provide water to the water tank kit (Fig. 3, 141 and 120 make up the water replenishing kit that provides water to the water tank 110)
The combined teachings can be modified to meet this/these limitation(s) as follows:
modify 2 of Ref. 1 so that is has a the water feed pipe and expansion tank 141 and 120 of Joo supplying water to 2 and an outlet 150 leading to a plumbing fixture
A person of ordinary skill in the art prior to the effective filing date of the claimed invention would have been motivated to make the above modification(s) because:
It would allow for the water tank 2 to be refilled and expanding water heated within the water heater tank kit of the combined teachings to be compensated for (Joo, Pg. 7, lines 17-22, As illustrated in FIG. 3, the water heater (100) according to the present invention has a hot water tank (110) that heats water through a heater (115) and stores the heated hot water, and an expansion tank (120) that receives hot water expanded in the hot water tank (110) when the hot water tank (110) is overheated.)
Regarding claim 19, the combined teachings teach of the digital boiler system of claim 18, and the combined teachings further teach:
further comprises an open expansion tank kit, supplying water to the water tank kit (Joo, Fig. 3, 120 is an open expansion tank that supplies water to the water tank kit)
Claim(s) 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gao (US 20200015383 A1) in view of DE 29813325 U1 hereinafter referred to as Ref. 1 and Joo (KR 20090129829 A) (previously cited) and in further view of Thomasson (US 9702586 B2)
Regarding claim 20, the combined teachings teach of the digital boiler of claim 18, however, the combined teachings fail to explicitly teach:
further comprises hot water reservoirs storing the water heated in the water tank kit.
Thomasson teaches of:
further comprises hot water reservoirs storing the water heated in the water tank kit (Fig. 1, the interior of 19 is a first reservoir and the interior of 31 is the second reservoir which stores the heater water from 19)
The combined teachings can be modified to meet this/these limitation(s) as follows:
add an outlet to tank 2 of Ref. 1 and connect it to additional tank 31 of Thomasson so that the heated water from tank 2 flows into the additional tank 31 of Thomasson and then flows out of 31 to a plumbing fixture so that the combined teachings has a first reservoir in the interior of tank 2 and a second reservoir in the interior of tank 31
A person of ordinary skill in the art prior to the effective filing date of the claimed invention would have been motivated to make the above modification(s) because:
it would allow for the water temperature within the tank 2 of Ref. 1 to be maintained at a much higher temperature allowing for a much larger amount of hot water to be maintained increasing the overall efficiency of the system (Thomasson, Col. 4, lines 43-47, Energy is absorbed in proportion to availability. By drawing hot water from the main water heater, the solar heated water is always mixed with cooler water yet the amount of available hot water is increased substantially, thereby improving the efficiency of the main water heater)
Claim(s) 24 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gao (US 20200015383 A1) in view of DE 29813325 U1 hereinafter referred to as Ref. 1 and Joo (KR 20090129829 A) (previously cited) and in further view of Bourke (WO 2006032083 A1).
Regarding claim 24, the combined teachings teach of the digital boiler of claim 18, however, the combined teachings fail to explicitly teach:
wherein the flow control valve is configured to simultaneously direct a first portion of the dielectric fluid through the heating coil in the water tank kit and a second portion of the dielectric fluid through the coil of the dry cooler, a ratio of the first portion to the second portion varying based on the temperature detected by the thermostat.
Bourke teaches of:
wherein the flow control valve is configured to simultaneously direct a first portion of the dielectric fluid through the heating coil in the water tank kit and a second portion of the dielectric fluid through the coil of the dry cooler, a ratio of the first portion to the second portion varying based on the temperature detected by the thermostat (Fig. 1, 26; ¶ [014], The bypass valve can operate over a range of temperatures to progressively open the bypass path and close the flow of heated fluid to the heat transfer means as the temperature increases within the said range of temperatures)
The combined teachings can be modified to meet this/these limitation(s) as follows:
modify 14, 16 9 and 10 of Ref. 1 so that 9 and 10 operate over a range of temperatures and gradually switch the flow of dielectric fluid from the tank to the dry cooler until the maximum temperature within the tank is reached
A person of ordinary skill in the art prior to the effective filing date of the claimed invention would have been motivated to make the above modification(s) because:
It would allow for more gradual control of the flow switching valve ensuring that the maximum temperature is not overshot within the tank (Bourke, ¶ [076], In one embodiment, the sensor/valve trip 149 can be set to cause the piston to gradually change over between the normal operating position and the over temperature position by gradually moving the piston as the temperature of the water enters a range of temperatures, finally cutting off the normal path when a maximum temperature threshold is reached)
