Depends on the size, the type of heating element, the water temperature and the ambient air temperature. I used to have a 300 gallon hot tub with a big natural gas heater; it took about 3 hours from "stone cold" to "102 degrees". I now have a 200 gallon tub with a small electrical heater; from 40 degrees to 102 degrees now takes about 20 hours.
Depends on what temp the water starts at and how hot you are expecting it to get. It will also depend on how powerful your heating element is for the hot tub. Typically you can expect about 1-2 degrees an hour. Within 24 hours a 500 gallon tub is typically hot! Leave the cover on the tub when heating it up. If you leave the cover off, a lot of heat can escape.
It depends on how slow you are
It takes about 3 days
Getting into a hot tub involves heat transfer through conduction and convection. Conduction occurs when your body comes into direct contact with the hot tub water, transferring heat from the water to your skin. Convection then takes place as the warm water circulates around your body, helping to further distribute the heat.
It is about £60 a- day but it all depends on what climate the tub is in and how hot you heat it to :) easy!
Hot tub covers can have long lives if they are cared for properly. Hot tub covers are mostly affected by dirt and sunlight so keep it clean and perhaps put a tarp over it if the hot tub is in direct sunlight.
Heat and dehydration. You risk heat stroke and death.
Sitting in a hot tub can lead to dehydration because the heat can cause your body to sweat more, leading to a loss of fluids. It is important to drink water while in a hot tub to stay hydrated.
Generally most hot tub heaters reach a maximum of 104 degrees Fahrenheit. Hot tub heaters are regulated to prevent excessive heat from harming our bodies. The following is a website that has a lot of detail about hot tub heaters. http://www.ehow.com/about_5031765_temperature-should-hot-tub.html
The time it takes to heat a 450-gallon hot tub depends on several factors, including the heater's BTU rating and the initial and desired water temperature. Generally, a standard electric hot tub heater (around 5.5 kW) can raise the water temperature by about 2-3°F per hour. Therefore, if you want to raise the temperature from 50°F to 100°F, it could take approximately 16-25 hours. For more accurate estimates, consult your hot tub's specifications and heater capacity.
The average-size hot tub holds approximately 475 gallons of water. The earliest known hot tubs were calderas. Hot stones were used to heat the water.
No, but hot tub folliculitis can be caused by hot tubs. See your health care provider for advice specific to your situation.
