1. A solar preheater, comprising: a central body having a base and an outer cover, wherein the base is arranged to receive the outer cover;a storage heater tank having a first top inner portion and a first bottom inner portion;a solar collector arranged between the base and the cover, wherein the solar collector comprises a solar collection surface;a cold fluid inlet tube having a first end and a second end, wherein the first end extends through the solar collection surface and past the outer cover and the second end extends through an opening and curves upwardly to discharge inside the first bottom inner portion of the storage heater tank;a hot fluid outlet tube having a first end and a second end, wherein the first end extends through the solar collection surface and past the outer cover, and the second end extends through an opening and curves upwardly to discharge inside the first top inner portion of the storage heater tank;a storage heater tank arranged between the solar collector and the base and configured to receive the cold fluid inlet tube in a bottom portion and the hot fluid outlet tube in a top portion;a first thermal collection mechanism and a second thermal collection mechanism comprising: a plurality of solar collector tubes, wherein each of the plurality of solar collector tubes comprises a first end removably attached to the base, a body that runs alongside the solar collection surface, and a second end removably attached to a central collector;a plurality of solar collector ribs, wherein each of the plurality of solar collector ribs is configured to latch onto each solar collector tube,wherein the first thermal collection mechanism is operated by heat transmitted directly from the plurality of solar collector ribs; andwherein the second thermal collection mechanism is operated by expanding and contracting the solar collection surface as each of the plurality of solar collector ribs forms or breaks contact with the solar collection surface; anda central tube placed inside the storage heater tank, wherein the central tube comprises a first opening operably connected to a base unit used to support the solar preheater over a surface that the solar preheater is placed on, wherein the central tube includes a plurality of lower recesses and a plurality of upper recesses configured to allow for fluid transfer. 2. The solar preheater of claim 1, further comprising a spacer comprising a non-conductive material to avoid formation of a thermal bridge between the storage heater tank and the outer cover. 3. The solar preheater of claim 1, further comprising a valve mounted over the central collector and configured to switch from an open position, allowing for fluid communication between each solar collector tube and the storage heater tank, to a closed position, foreclosing fluid communication between each solar collector tube and the storage heater tank. 4. The solar preheater of claim 3, further comprising a thermal actuator arranged to move the valve from the open to the closed position. 5. The solar preheater of claim 1, wherein the solar collection surface comprises a first conductive material layer. 6. The solar preheater of claim 5, wherein the solar collection surface comprises a second thermal isolating material layer. 7. The solar preheater of claim 6, wherein the solar collection surface comprises a third reflective material layer. 8. The solar preheater of claim 7, further comprising a thermal isolating material tank layer used to isolate the storage heater tank. 9. The solar preheater of claim 1, further comprising a diffuser housed in the storage heater tank and configured to receive discharge of contents from the second end of the cold fluid inlet tube. 10. A solar preheater, comprising: a central body having a base and an outer cover, wherein the base is arranged to receive the outer cover;a storage heater tank having a first top inner portion and a first bottom inner portion;a solar collector arranged between the base and the cover, wherein the solar collector comprises a solar collection surface, the solar collection surface comprising a central tube configured to support the solar preheater, wherein the central tube comprises a first opening operably connected to a base unit used to support the solar preheater over a surface that the solar preheater is placed on, wherein the central tube includes a plurality of lower recesses and a plurality of upper recesses configured to allow for fluid transfer;a cold fluid inlet tube having a first end and a second end, wherein the first end extends through the solar collection surface and past the outer cover and the second end extends through an opening and curves upwardly to discharge inside the first bottom inner portion of the storage heater tank;a hot fluid outlet tube having a first end and a second end, wherein the first end extends through the solar collection surface and past the outer cover, and the second end extends through an opening and curves upwardly to discharge inside the first top inner portion of the storage heater tank;a storage heater tank arranged between the solar collector and the base and configured to receive the cold fluid inlet tube in a bottom portion and the hot fluid outlet tube in a top portion;a first thermal collection mechanism and a second thermal collection mechanism comprising: a plurality of solar collector tubes, wherein each of the plurality of solar collector tubes comprises a first end removably attached to the base, a body that runs alongside the solar collection surface, and a second end removably attached to a central collector;a plurality of solar collector ribs, wherein each of the plurality of solar collector ribs is configured to latch onto each solar collector tube,wherein the first thermal collection mechanism is operated by heat obtained transmitted directly from the plurality of solar collector ribs;wherein the second thermal collection mechanism is operated by expanding and contracting the solar collection surface as each of the plurality of solar collector ribs forms or breaks contact with the solar collection surface; andan electric heater comprising a housing and one or more resistive heating elements, the heater configured to heat fluid stored in the storage heating tank. 11. The solar preheater of claim 10, wherein the electric resistor comprises coating for reducing plaque formed over the electric resistor and for allowing the solar preheater to be operated autonomously. 12. A method of using a solar preheater to receive solar radiation, comprising: using a plurality of ribs to transmit heat toward a top portion of a collector tube;expanding a solar collection surface to contact a bottom portion of the collector tube;moving a thermal actuator using a thermal collection surface; andopening a double-seated valve configured to allow fluid communication between the collector tube and a storage heater tank.
