Abstract

Form 24 (ss 21. 31. 34 and 142) ABSTRACT
The idea of saving energy by turning off electric or gas water heaters during low- or no-demand periods is not new. However, the concept of automatically controlling the times on a fixed schedule is revolutionary. The new invention, Energy Saving Device, is a computerized hot-water tank energy-use manager that can enable users to save a significant amount of money on their monthly water heating bills through efficient and comprehensive control of the heating unit.

Energy Saving Device is a programmable, computer-controlled device that controls water heater duty cycles over a period of hours, days and weeks. A control panel is provided for the user to change the shut-down schedule, manually over-ride the system and monitor current system settings. The device works with both electric and gas water heaters. An additional solenoid controlled valve is required for gas units.

SPECIFICATION
Thls Invention relates to a device that can control the flow of energy, electrical or hydrocarbon~ ~upplied to a hot water tank.
At present, a hot water tank malntains a supply GY hot water 29 hours a day, regardless of demand. This practice is very lnefflcient slnce energy ls con~umed malntalnln~ this supply of hot water, even though it may not be needed for several hours lnto the future.
I have found that enerqy can be saved by lnterruptln~ the flow of ~uel~(electrical or hydrocarbon) supplied to a hot water heater durlng the tlme(s) of a no load demand. An example o~ this could be at night time when hot water ls beinq maintalned at a preset temperature, but not consumed. To achleve thls, a programable machine is used to turn "ON" or "OFF" a remote switchlng apparatus, ie:relay or valve located on the energy supply line fed to the heatln~ element, dependant on user deflned demand times. Thls inventlon will therefore ellmlnate the overall consumption of energy needed to op~ate the water heatlng devlce~
. .
In drawings whlch lllustrate embodlment~ of the lnvention.
Flgure 1 ls the overall view of the control system.
Flgure 2 ls the ma~or component outllne of the computing devlce.
rhe device illustrated com~rlse~ of a maln control unlt that contalns the calculating dev ce, and remote swltching device th.3t contain3 the ap~aratus required to turn "ON" or "OFF" the flow ~,~ cner(3y fe(3 to the heatinc~ element.
The main control unlt contains a computing device that ls used to perform calculatlons on the data stored ln lts memory, or to ~ta entered lnto It by Its programmer. Whel) the user enter~ the requlred "ON" or "OFI~" tlme(3) of day vla a keyboard, the calculatlng devlce will then store this lnformation lnto lts memory for future use. By u~lng thl~ informatlon ln con~unctlon wlth ~reprogrammed data, the unlt wlll be capable of determlnlng when t~e output ~Ignal fed to the swltchlng apparatu~ 3hould be changed.
The computlng device is al30 capable of calculatlng the lead tlme re~ulred to roturn the water to the temperature o~ thc hot water he.1ters temperature 3et-point.
On command from the computlng device, a ~lgnal 1~ sent to an ellergy control swltch,ie:relay or valve,whlch ln tllrn controls the energy flow to the heating unlt, turnlng lt "ON" or "OFk".

Claims (4)

1. A device that can be programmed to control the flow of energy supplied to a water pressure vessel heating device.
2. A device as defined in claim 1. in which the flow of the heating medium energy source supplied to a water pressure vessel heating device, can be turned on or off by a remote switching unit.
3. A device as defined in claim 1. or claim 2. in which a person can program the time or times of day that the energy is supplied to a water pressure vessel heating device.
4. A device as defined in claim 1. 2. or 3. that can calculate the time required to reheat water to the value set by the water pressure vessels temperature control system.
