No, it rises slower. The temperature in the hot tub changes because hotter water is introduced as cooler water is removed (to be heated). The hotter water mingles with the cooler water, and their temperature balances to an average.

That average will appear to increase rapidly initially. Then that rise will taper off as the hot tub temperature approaches the same temperature as the heated water being pumped into it. Mathematically: If the hot tub starts at 70 degrees and half of that water is pumped out and replaced with 110 degree water, the new temperature will be 90 degrees: (110 + 70) / 2 = 90.

A change of 20 degrees. If it happens again, the new equation is (110 + 90) / 2 = 100. A change of only 10 degrees.

This is simplified of course, but it demonstrates the basic principle. I hope this helps.

Nope Probably not. Most hot tubs have an electric or gas heater. These both transfer about the same amount of heat per second, not very dependent on the water temperature..

1 I'n not sure what you are asking, but if the question is whether the rate of temperature rise increases as with the temperature, the answer is a definite "No". The specific heat of water is not very temperature dependent and all the rates of heat loss go up as the temperature increases, including losses due to evaporation, conducction, convection, and radiation. All of these will slow the increase down.

This will ultimately cause the temperature to reach a limiting value.

It might all be the same unit (a closed system), but the heater is not in the water next you. It is separate. Cool water flows out of the sitting area of the hot tub, into the heater, and hot water flows out of the heater, and into the sitting area of the hot tub.

I get pretty consistent hot water out of the shower head, but the tub starts hot and gets cold. What could it be?

Cold water is coming out of the hot water faucets.

Were is the valve that conyrols hot and cold water in the tub.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
