Construction and design elements involved in a spa or hot tub

The design and construction of the spa is the most important aspect in determining the cost of operation.
While the preceding factors indeed may affect cost, design and construction can dramatically affect the cost
of operation. Imagine two hot tubs identical in size, holding the same amount of water, located in the same
backyard, used identically, but that have dramatically different operating costs. How could one of these hot
tubs cost $20 per month to operate and the other cost $100 per month to operate? The difference between
the two spas is based on the following three important cost-saving factors:

Method of Insulation.
Imagine a $4000 spa that costs over $100 per month to operate, while a $6000 spa costs only $20 per
month to operate. Why such a difference in operation costs? The methods of insulation. Of all the factors
previously mentioned, nothing is more important than having the proper insulation in your hot tub.
Sometimes paying more in the beginning for your hot tub will end up saving you significant amounts of
money down the line.

Over 95% of spa manufacturers offer one of the following methods of insulation: basic insulation, full foam
insulation, and layered insulation. We highly recommend looking for a spa with proper full foam insulation for
cost efficiency. When looking for a spa, look for insulation with a high R-value that is installed behind all four
walls of the cabinet, as well as the base. Check how the manufacturer installs their plumbing as well.

Built-In Energy Saving Features.
There are many different features offered on today's hot tubs that can save on the cost of operation. The
following are some features to look for in your hot tub:

(1) Economy Mode Operation.
This feature, regulated by the control panel, lowers the water temperature when the spa is not in use,
reducing the cost of operation by up to 20%.

(2) Automatic Shut Off.
This control panel feature turns off the spa's pumps, blowers, and lights within a set amount of time if and
when you forget. This not only saves on operation costs, but also helps to extend the life of your equipment.

(3) Diagnostic Fault Display.
This control panel feature acts as a troubleshooter for your spa, often allowing you to solve many problems
over the phone. This can eliminate the need for costly service calls.

(4) Automatic Freeze Protection.
This feature turns the water pumps on in freezing weather if your spa's heater should ever fail, saving you
from expensive repair costs.

Quality of Cover.
The cover retains the spa's heat and moisture, therefore, it is imperative to look for a quality cover to keep
operation costs at a minimum. We recommend looking for a 1.5 lb. foam density cover for the best energy
efficiency. Also look for heat seal gaskets that will protect against vapor loss in the cover's crease. In addition,
look for a cover that has at least a 4" skirting that covers the spa's shell and a portion of its cabinet.
