1. A heat transfer unit for a prefabricated vessel, the heat transfer unit comprising:
a central rod;
a plurality of peripheral rods surrounding the central rod and connected to the central rod, each of the plurality of peripheral rods extending between a first end and a second end, the first end and second end of each of the plurality of peripheral rods connected to the central rod, the plurality of peripheral rods movable between a first collapsed position and a second bowed position, wherein in the second bowed position a midpoint of each of the plurality of peripheral rods is spaced from the central rod relative to in the first position, and wherein a distance between the first end and second end of each of the plurality of peripheral rods in the second bowed position is less than a distance between the first end and second end of that peripheral rod in the first collapsed position, and wherein each of the plurality of peripheral rods is biased towards the second position when in the first position such that each of the plurality of rods returns to the second position when not under the influence of an external biasing force or wherein each of the plurality of peripheral rods is biased towards the first position when in the second position such that each of the plurality of rods returns to the first position when not under the influence of an external biasing force; and
a heat transfer element connected to one of the plurality of peripheral rods.
