Immersion Heater Tank - Why is it domed at the bottom? Just wondering why the Copper Immersion tanks are domed at the bottom?...
Just wondering why the Copper Immersion tanks are domed at the bottom? - nearby must be a valid reason for it???
Answers: Your hot river storage cylinder (immersion heater tank) is subjected to dampen pressure, either from the cold marine tank surrounded by the roof if you have what is call a vented system or from the D water supply if you hold an unvented system. A domed surface can withstand this pressure better than a flat surface. The top of your cylinder is also domed for this reason. If it be flat, when under pressure, it would try to distort into a domed shape. This is also the motivation why large circular buildings similar to St. Pauls Cathedral have domed roofs. Imagine what would transpire to a boxed shape football if you tried inflating it. (perhaps not so bad, it might administer Pompy a better chance)
correct answer .... good
