Curious question, figured what better place to ask than the physics forum.
So I just picked up a used hot tub. Was running great when I bought it. Filled it up with water, turned it on, started its cycle. It can take over 24 hours for the tub to reach 102 degrees.
There's a 12 inch heating tube in which water rushes past, "heating" the water which gets pumped back into the tub. Now I when I touch the heating tube, it doesn't feel hot to the touch. Though perhaps it won't feel warm/hot until the water equalizes in temp? Perhaps a strong flow of freezing water would essentially cool the heating element just as much as it would be heating it up, so I wouldn't immediately feel the tube get hot?
Anyone have any thoughts on this? (or perhaps it should get piping hot immediately and my heater is busted) I'm thinking I should feel some sort of heat...
