In one aspect, the heated liquid for a self-power pump is provided. And the pump comprises an airtight container containing a heated liquid. Heated liquid inlet pipe extending to the top in the container, an end of the inlet pipe is positioned in the container. Heating the liquid outlet is located below the end of the inlet pipe. Bleeding pipe which extends up into the container, an end of said breathing pipe is positioned within a container, positioned higher than both ends of the outlet and inlet pipes, but is positioned lower than the inner side of the upper part of the container. The opposite side end of the breathing pipe is located on the outside of the container, located below the said container base, be received by the open container, the side opposite to the terminal can be locked out in heated liquid accumulated within said open container during pump operation. Self-fluid or liquid heating system incorporating the pump power can be operated without an external source of power for the pump. In another embodiment, the fluid heating and storage tank is provided. And wherein the tank includes a device for inducing a second fluid through the, storage tank is isolated from the first fluid inlet and a storage for a first fluid having a first fluid outlet tank, and the first fluid. The apparatus includes first and second pipes and heat exchanger. The first pipe extends through the storage tank, is attached to the first and second fittings of the wall of the storage tank at the end of the first pipe. The second pipe also extends through the storage tank, it is mounted to the third and fourth fitting in the wall of the storage tank at the end of the second pipe. The heat exchanger is thereby disposed in the storage tank and fluidly interconnecting the first pipe and the second pipe. The tank may be formed as one or more upright orientation. Fluid comprising a fluid heating and storage tank, and a heater heating system, in different embodiments, or to use a pump for circulating a second fluid through a heater which may be a solar heater can not be used.
