How Much Electricity Does a Swim Spa Use?

You may be looking for a swim spa because you don’t have enough room in your backyard for a full-sized swimming or lap pool.  Or maybe you’re enticed by the thought of being able to afford a place to swim and soak in a hot tub without buying two completely separate units.  You might be attracted by the fact that a swim spa should be cheaper to run than a full-sized swimming pool and complimentary hot tub.  But then this might get you wondering how much electricity does a swim spa use?  In this article, we’ll go over some of the factors that affect the operating cost of a swim spa and give some tips on how to keep these costs as low as possible.

Swim Spas and Your Electricity Bills

Determining the actual cost of operating a swim spa will depend on a number of different factors which may be hard to generalize for owners in different parts of the country.  Of course, the cost of electricity in your area will be the leading indicator of what your actual electric bill will work out to.  Beyond your local rates for electricity, there are a number of other variables which will affect your operating costs.

Swim Spa Size

The size of your swim spa will play a role in the size of your electricity bills.  It only stands to reason that a larger swim spa will cost more to operate than a smaller one.  But buying a small swim spa to save money on your electricity bills may be looking at the situation from the wrong angle.  You’re going to want to buy a model that works best for the number of people you expect to be using it and how they plan to use it.  If you fixate on operating costs to the detriment of comfort, you may end up with a large purchase that doesn’t achieve its full potential. 

Amount of Use

The amount of use that your swim spa gets will also determine how much it costs to run.  The bills of a family that uses their swim spa on a daily basis will naturally be higher than that of a family that practices their stroke once or twice a week.

Type of Use

Some people like to use their swim spa simply as a place to cool off.  Others take their swimming practice very seriously.  Whereas others prefer to turn up the water temperature and soak away their aches and pains.  The type of use your swim spa gets will affect your electricity bills accordingly.


Those who live in relatively warm climates will not have to pay as much to keep their water heated compared with those who have harsh winters.  And unlike swimming pools, it’s possible to keep your swim spa running all year round regardless of how cold your winters get.  But you’ll definitely pay for the pleasure.


The amount of insulation that surrounds the cabinet of your swim spa will play a significant role in how much it costs to keep your water at a constant temperature.  Inground models benefit from the insulating properties of the ground that surrounds it.  For above-ground models, the type and amount of insulation you choose should be dependent on the climate in your area.  The colder the climate the more cost-effective extra insulation will be.

Water Temperature

To keep your electricity costs to a minimum it’s best to keep your water temperature constant.  This means leaving the water heater running when the system isn’t in use.  It may seem like this will cause your electric bills to skyrocket, but it will actually take much more electricity to bring your water up to temperature every time you want to use your swim spa.  Set your preferred temperature and leave it there.
