Fast Heating: Gas heaters are the clear winners when it comes to the speed of heating. A gas spa heater can add 1-2° per minute, whereas an electric heater may take an hour to add a few degrees. This lets you keep the spa at a lower resting temp, and heat it up quickly as needed.
If you have a 1,200-gallon hot tub and your gas heater runs on natural gas, $1 will be needed per unit of natural gas to heat your hot tub water in 30 minutes to 93 degrees. Since you require 4.71 therms to heat your hot tub water daily, it will cost you $4.71 per day of heating the water.
Modern manufacturers advertise the cost to run their hot tubs at about one dollar per day, with $50 per month at the high end. The energy cost of a hot tub varies based mainly on the heater, which usually draws between 1,500 watts or 6,000 watts.
According to the US Consumer Product Safety Commission, the water temperature of a hot tub is best between 100°F and 102°F.
Most spa owners expect their heater to take no more than 15 to 30 minutes to heat their spa to 102°F.
Before covering your hot tub, make sure to turn on the jets as this will accelerate the pace of your hot tub's heating. By running the jets, you're allowing the heated water to be circulated and evenly distributed to all areas of the hot tub.
So, what is the ideal hot tub temperature when not in use? A good rule of thumb to follow is always keeping your hot tub's temperature 5 degrees below what it usually is.
The maximum temperature of any given hot tub is almost always 104 degrees. On the other hand, most hot tubs have a minimum temperature of about 85 or 90 degrees. There are exceptions, though. Some hot tubs, such as those which use AnyTemp® spa technology, can reach temperatures as low as 62 degrees.
One question we sometimes get asked is should I leave my hot tub on all the time? The answer is yes! Hot tubs are designed to be left on permanently and this is how they work best. Of course, they'll need to be drained regularly but for the most part, they are left on 24/7.
Most hot tubs can be set as low as 26°C, but this would only be appropriate if it is a hot summers day and you want to use your tub to cool off. The maximum safe recommended hot tub temperature is 40°C, as anything higher than this can be dangerous, posing serious health risks to users.
For most people, a hot tub is worth the money if you use it regularly—and don't mind spending the time and energy it takes to maintain it. A hot tub can be a fabulous luxury. However, an unused hot tub is an expensive waste of energy, and a poorly maintained one can pose health risks.
Lay-Z-Spa Weekly Running Costs in the UK
The estimated running cost of a Lay-Z-Spa is around £7 - £10 a week. These estimates are based on the Vegas Airjet Model being used 3 times a week in the UK's average summer temperatures.
Although they are usually kept at temperatures between 99° F to 102° F, with a maximum heat of 104°F, you can lower the temperature for summertime use. Simply lower the temperature of your hot tub to roughly 85°F or turn off your heater altogether.
Propane gas is more costly, but produces slightly more BTU's than natural gas. Fast Heating: Gas heaters are the clear winners when it comes to the speed of heating. A gas spa heater can add 1-2° per minute, whereas an electric heater may take an hour to add a few degrees.
#1 Turn the temperature down on your hot tub
The easiest way to save money on your hot tub is to turn the temperature down a few degrees. Each degree will save you approx. 10% on your hot tub energy bill.
When it comes to hot tubs and spas there are really two ways of heating them. The first is gas and the second is electric. Gas hot tubs or gas-fired hot tubs use small swimming pool heaters to heat the water (around 100,000 BTU). These heaters can be natural gas or propane gas.
By draining and refilling with fresh water on a regular basis, you'll ensure your hot tub is clean, clear and safe. But the question is: how often should you do it? With average use, your hot tub should be drained and refilled about once every three or four months.
Yes! Hot tubs run on an electrical supply. They usually need between 13 and 40 AMPS of power to run. The electricity powers the heater, pumps, lights and all the other working components on the hot tub.
Draining Your Hot Tub For Winter
Although we recommend using your hot tub as normal during winter, some users will prefer to winterise (drain and turn off) their spa. This needs to be done thoroughly to ensure no issues occur when the hot tub is empty.
If you're a healthy adult, it's safe to use your spa at 102°F for as long as you wish. If you're over 65, even if you're in good health, you should consult your doctor to determine what's right for you. In many cases, you'll get the green light to stay in the spa as long as you're comfortable and feeling well.
Winter is a wonderful season to use a hot tub. The hot water & massage breathes life back to frozen feet and aching joints. Instead of winterizing the spa for the cold, why not make the most of your investment and enjoy it? New, energy saving hot tubs stay hot and ready all winter, without adding to your electric bill.
Well, in the case of your hot tub, it might not be the best idea. With the hot tub off, it will be unable to circulate and filter the water, that means stationary water which isn't being circulated. Water sitting in the pipework could end up going stagnant and causing problems when you return.
Temperature Limits
It is important to ensure that you stay under the recommended Maximum Temperature for Hot Tubs, which is 40°C/104°F. By exceeding the 40°C/104°F recommended temperature limit, you are putting your body at risk – let's all stay safe so we can carry on enjoying our tubs!
The maximum recommended temperature for a hot tub is 104°F (40°C), but that doesn't mean you have to keep it there. Setting a lower hot tub temperature will save energy and money, and will reduce evaporation, thereby preserving the chemicals in the water.
Health Benefits
The heat widens blood vessels, which sends nutrient-rich blood throughout your body. Warm water also brings down swelling and loosens tight muscles. And the water's buoyancy takes weight off painful joints. A dip in the hot tub might also help your mental state.
