How Much Electricity Does A Hot Tub Use?

Having your own personal hot tub is the perfect way to soothe sore muscles and unwind, however, many people want to know how much electricity a hot tub uses before deciding to make a purchase. The truth is that hot tub electricity consumption can vary based on a number of factors, including the quality of the model.

Read below to find out how much electricity a hot tub should use as well as tips on how to select an energy efficient model so you are not faced with a soaring utility bill.

Heating Costs

The electricity cost of your hot tub depends on several factors – the water temperature, the unit price per kilowatt hour as well as how frequently you use your hot tub. Typically, with a quality, energy efficient model, you can expect to pay less than £.076 per day. Be aware of buying a cheap hot tub, although the upfront price tag may seem attractive, they will almost always cost more in the long run. Low-quality models with poor insulation can easily double your hot tub energy consumption.

How to Save

If you are running your hot tub 24/7, your hot tub will be using more electricity, however, there are some ways that you can reduce the operating cost. Look for a model that has a circuit timer which can be programmed to heat your tub during off-peak hours to save on your per unit energy costs. If your hot tub does not have a circuit timer, you can always manually reduce the water temperature by a few degrees when the hot tub is not in use.

Water Volume

Another factor to keep in mind is the water volume of your hot tub. An average sized hot tub will hold approximately 250 gallons of water, however, larger models can hold up to 500 gallons. The more water that is in your hot tub, the more electricity usage it will require to keep the water heated.

If you are shopping for a hot tub and want to ensure that you choose an energy efficient model, here are the top features that you should look for.

Hard Covers

A heat shield, hard cover for your hot tub is one of the best ways to retain heat, saving on electricity consumption. You want to choose a well made, durable and lockable cover that features a tapered design and has insulation baffles around the fold. A quality cover will keep the cold air out and the heat in.


The faster your hot tub can filter its water, the more energy efficient it will be. In fact, Hydropool manufactures some of the most energy efficient hot tubs in the world – boasting an impressive filtering speed of just 15 minutes for all the water in your tub.

Efficient Pumps

An energy efficient pump can reduce your hot tub energy consumption by 25% compared to other pumps. Look for a pump with the highest flow rate with the lowest energy output.

CEC Certified

If you want the highest standard in energy efficiency for your hot tub, choose a CEC certified model. The California Energy Commission is a strict guideline that is only awarded to hot tubs which are the top of the line in energy efficiency standards.
