Hot Tubs Fact Sheet: Energy Efficient Hot Tub or Spa

Not all Hot Tubs are built the same. While most manufacturers offer an energy efficient hot tub, the true cost of owning and operating a hot tub is not usually revealed until you get it home. Recent advancements in engineering and technology by hot tub & spa companies like Arctic Spas have made great improvements in reducing operating costs that go along with owning a hot tub or swim spa.

The last thing you need to worry about when relaxing in your hot tub is the cost to operate it. At Arctic Spas, we are transparent about the cost of operating our Hot Tubs. Every Arctic Spas hot tub is designed with FreeHeat™ Technology and retains ambient heat from the pump motors, operating costs are about $1 per day. Talk about a low-cost, high-reward investment!

Let’s learn about the most recent improvements that can have a significant impact on your utility bill.


Choose the Most Energy Efficient Hot Tub

Purchasing a hot tub for your home is an investment. It can be tempting to stick to a tight budget and purchase a lower cost hot tub. The problem with this is that the upfront savings result in increased long term costs. We think you will find that purchasing a higher quality tub means you’ll save significantly in monthly operation costs.

Heating costs are the #1 ongoing expense of operating a hot tub. Maintaining water temperature is key. The more you have to heat a tub, the higher your energy bill will be at the end of the month. Let’s explore some Energy Saving features.

Energy Saver Hot Tub Features

When looking for an energy-efficient hot tub, there are certain features you need to keep an eye out for. Pay attention to the cover, tub wall insulation, and pump system.


It’s vital that your hot tub has a well-insulated cover that creates a tight seal on the top of the tub. This will trap the warm air and energy in the tub. Even a small leak will increase the evaporation rate, which also increases the dissipation of heat.

You should choose a cover with closed-cell insulation. This will reduce water absorption and increase the useful life of your cover. Our Mylovac™ cover is an upgrade that’s well worth the investment. It features foam twice as dense as the industry standard. The insulation is then wrapped in a polybag material and vacuum sealed. This sealed insulation is then paired with locking straps, carry handles, longer wind flaps, and insulating baffle to give you the most protective cover on the market.

Tub Wall Insulation

Your next step is to look at the insulation around the tub walls. Many lower-quality tubs lack sufficient insulation in this area. Look for a tub with thick wall insulation around five inches. Keep in mind that thicker isn’t always better. Insulation follows the rule of diminishing returns, so you get a smaller and smaller benefit, the thicker the insulation.

We sell hot tubs with a FreeHeat™ Perimeter Insulation System. This unique system uses high-density polyurethane foam from the lip underside and on the entire cabinet wall. You’ll never see fiberglass used, which is a cheap and ineffective insulation material for hot tubs because there’s a high risk of it getting wet and becoming ineffective.

Pump System

The pump for your hot tub needs to combine water flow and efficiency. Our AquaFlow Pumps do just that by pulling minimal amperage while also producing extremely high volume water flow. At low speed, the pump can move 50 gal/min through the filters.

Select Your Energy Efficient Hot Tub

As you can see, an energy efficient hot tub will make a significant difference in your expected operating costs. To know if a hot tub is energy-efficient, look at the cover, wall insulation, and pump. This will tell you how much energy the tub needs to run and how well it will retain the heat that’s generated.
