What is the Most Efficient Hot Tub?

Although it might not be the first thought you have when considering buying a hot tub, taking some time to think about its energy efficiency can play a big role in the future enjoyment of your new purchase.  After all, who wants the time that’s supposed to be spent relaxing in the hot tub to be riddled with worries about how much it’s costing to keep the thing running?  By investing in energy-efficient components from the outset you’ll be able to enjoy the full use of your hot tub with the comfort that you’re not needlessly wasting money or power.  To answer the question of “What is the most efficient hot tub?” we’ve come up with a list of components that contribute to a hot tub’s overall performance.

Hot Tub Cover

The hot tub cover is probably the most important piece of equipment on a hot tub when it comes to conserving heat.  Most of the heat that escapes from the hot tub is through the water’s surface.  And although there’s not a lot that can be done about that when your hot tub is in use, it’s a fact that your hot tub will sit unused much more than it will be full of people.  And this is where a well-insulated hot tub cover is worth its weight in energy savings.  It becomes even more important in cold climates.  Make sure to invest in a properly fitted and well-insulated hot tub cover to reduce your energy bills as well as the time you have to spend waiting for your hot tub to get up to temperature before use.

Hot Tub Cabinet

Another hot tub component that needs to be well-insulated, especially in colder climates, is the hot tub cabinet.  After the water’s surface, the walls of the hot tub shell and cabinet are where most of the hot tub’s heat will escape from.  By ensuring that the cabinet is properly insulated you’ll be reducing your energy bills as well as the time it takes to heat up the water.

Heat Exchanger

The water pump and heating system are another area that can be very energy inefficient if not properly acknowledged.  Both these motorized parts create a lot of heat that is simply lost to the environment under normal conditions.  However, investing in a heat exchanger can redirect this wasted heat back into the water.  This reduces the reliance on the heating system and brings down your overall energy usage.

Water Heater and Pump

Water heaters and pumps are the biggest energy users in the hot tub system.  For the most energy-efficient system, look for units that rely on lower amperage while maximizing the water flow.  This will ensure the water is heated and circulated at a much lower cost than less efficient systems.


The filtration system plays a large role in keeping the water clean and fresh.  The more efficiently that a filtration system can cycle through the entire contents of the hot tub the less it needs to be used and the lower your energy bills will be.  Some filtration systems can cycle through the full volume of the hot tub over the course of a single soaking session. 

Automated Controls

A programmable control system allows the running of the hot tub to be automated.  Similar to a thermostat, such a system reduces the need to constantly monitor the water heater and pump.  Not every model features these types of controls, but they can greatly improve the efficiency of your hot tub.
