How much Electricity does a Spa Pool and Swim Spa Use?

Spa pools: the ultimate symbol of luxury. Whether you call it a swim spa, a jacuzzi or a whirlpool - there is no better way to relax and heal your body at the end of a long day. However, the cost of running a spa pool is a universal concern among prospective buyers – often the only thing standing between somebody and their own personal spa tub.

The heater in the spa pool is the main electricity siphon, ranging between 2000 watts (2 kWh) up to 9000 watts (6 kWh) in larger models. Most are around the 3000-4000 range. The pumps vary, but usually run around 1500 watts, making the average around 5000 watts (5kWh).

The main concern with all prospective spa pool owners is, “How much is that going to cost?” This post will provide an overview, including how much your spa pool will cost to run, how you can keep your electric bill low and exactly which spa pool is perfect for your needs.

How much does it cost to run a spa pool or swim spa?

The good news is that the bulk of the costs associated with a spa pool is paid upfront. It is best you spend more money upfront if you want to save on electricity. The primary way that manufacturers reduce running costs is by way of spa insulation, and this can get expensive. Spa pools are an investment, and the more money you put in initially, the better quality you can expect. You can also expect your electric bill to be far larger if you try to save some money upfront on your tub.

For a high-quality, well-insulated and energy efficient model from our premium Hot Spring collection, you can expect to spend about a dollar a day to operate your tub. For a lower quality or under-insulated model, costs can run as high as 5 dollars a day. Much of the costs are dependent on two factors: your electric provider and the climate you live in.

In New Zealand, the leading providers of electricity for the North and South Island respectively are Genesis Energy and Contact Energy. The average monthly Genesis bill in the North Island is about $200, whereas the average monthly contact bill in the South Island is about $171.

Let’s say you’re really excited about your new purchase, and you hop in the spa every day for the first month. This means a poorly-insulated but fully paid off spa pool could end up costing you over $150 a month – almost doubling your electric bill. A disappointing scenario for spa owners is they consequently don’t end up soaking as much or worst case, drain the spa water and leave the spa switched off due to the high energy costs to regulate heat in the winter. 

Investing in a high-quality tub will not only save you money on future electricity bills but has the added benefits of guarantees and reliability. Used the exact same amount, a well-insulated spa pool could cost as little as $30 a month! 

For comparison, the low quality spa pool would take up between 43-47% of your electric bill depending on where you reside. Meanwhile, a high quality spa pool would only be 6-7% of your monthly electric bill. 

We are proud to be the only spa company to have our running costs independently tested and proven. If you would like an assessment, our spa pool energy calculator will give you an indication of costs based on the spa model and climate. 

Does my location impact my spa pool electricity spend 

To a lesser extent, where you live also plays a key role in understanding how much your spa pool will cost to run. In a relatively static climate such as in Auckland, running a premium spa pool every other day could cost you around $40 a month in summer or about $70 a month in winter. A name-brand spa such as Hot Spring could use almost 50% less electricity in the same time, whereas a budget spa might use 20-30% more electricity – costing you more in the long run.


How can I reduce the amount of electricity my spa pool uses?

The amount of electricity you use will also depend on how you use your tub. For example, it’s better for spa pools to have a circulation pump and massage jets pump. Your tub draws far less power running on just the circulation pump than the massage jets so consider this when making your purchase.

While investing in a well-insulated tub will get you a step ahead in reducing costs, there are a couple of other handy tips that can save you money in the long run. With a bit of extra investigation, you can find out exactly how easily you can save money on your spa. Download our Energy Efficiency Checklist to unlock more helpful energy features when considering your spa pool purchase. 


Heat pump systems are more efficient than electric element heating units

The primary energy draw in an electric spa pool is the heater. Spa pool heaters are generally capable of raising the temperature about one degree Celsius per hour, no matter what heating unit you use. Conventional, built-in heating units use an electric element to heat the water. This is a hassle-free and convenient way to enjoy your tub. However, if you’re looking at saving some money, you should look at a heat pump for your tub.

Spa pool heat pumps use air flow instead of the standard element method of heating your tub. While they heat at about the same pace, heat pumps are a more energy-efficient method of raising water temperature. Generally, these are external units, and if you’ve already made the purchase, you’ll have to get a spa technician to install it near your tub.
