Tub Electrical Question
« on: December 17, 2004, 09:41:18 pm »
Probably a dumb question but here goes:

Is it cheaper to set you tub at 80 degrees in the winter time if you are not going to use it versus just keeping it at 100?  My heater turns on when it reaches 2 degrees below the set temperature.  So, in other words,  does it cost more to maintain a tub temperature of 100 degrees or 80 degrees?

My first thought would be 100 would be more expensive but once your tub gets down to 80 degrees, is there really a significant difference in the time it takes to go from 80 to 77 versus 100 to 97?  

I am sure I learned the answer to this many years ago in school but have since destroyed those brain cells enjoying alcohol in the tub

I would think this would depend on several factors.


What kind of spa do you have?

What type of insulation does it have?

What size is your heater?

it is easy....

heat loss is a function of temperature differential.

so 80 degrees will use less energy.

This question has two answers. One would be the answer which would include a lot of arguing over minutiae and physical laws and stuff. It would only be proved or disproved in a lab.

The other answer is much more practical, and applies exactly to your spa: "try it and see."

I think the only answer worth anything for you is the second one.
