The question that drives almost every hot tub owner crazy is what the hot tub temperature when not in use is? This specifically applies to the more extended periods, when you’re not in a position to control the temperature manually. To put it simply, what temperature should you set your tub in when you’re heading out for a vacation? While you’d find many resources online, Richard’s Total Backyard Solutions suggests you to set this around 5 degrees lower than the original temperature. Depending on your climate, this will keep your water warm enough for it to reach the operating temperature zone quickly. Additionally, it also won’t waste any energy at the due moment.

However, if your vacation is an extended one for a week or more, or if it’s during the winter, it is perhaps a better idea to lower your temperature an extra notch. This is also viable from the perspective of energy savings. Many people try saving energy (while they’re on vacations) by either timing or shutting their lights and temperature control units. And guess what? This same logic applies to your hot tub as well. As you do this, you end up spending your days comfortably, knowing that there’s no unnecessary energy wastage.

Of course, you’re required to maintain some basic warmth in the tub water, regardless of the duration of your vacation. After all, none of us want to head back home to an icy cold bath. It is also not very energy efficient to spend a huge chunk of time in bringing your tub’s water to your preferred level of temperature.

Here, it is important to note that none of your hot tubs are perfectly insulated from the surrounding environment. Therefore they are constantly losing a small amount of heat leading your heaters and pimps to come on at periodic intervals.

Yes. The bigger difference you have between the temperature of the water and the surrounding environmental climate, the faster will your heat escape. This also means that when you’re not using the tub, getting the temperature down will save energy by keeping your heater at an optimal temperature. Although heating this tub back might consume some amount of energy, a longer duration of low water temperatures will be more than enough to make up the deficit.

Due to this reason, we’d suggest you to lower the temperature by 10 degrees if you’re heading for a vacation which is for around 7-10 days. This will let your system preserve minimum heat without uselessly using up the energy. The only issue with this system is that you won’t really be able to use the tub immediately after return. But that’s still worth a shot from the energy savings perspective.

So now that you know about the what the hot tub temperature when not in use is, start following this guideline right away to save on your energy bills like you always wanted to. Always remember that a rule of thumb to follow is keeping your hot tub 5 degrees below what it usually is.
