Using A Hot Tub
Spa Outside In The
More and more people are using their hot tubs outside
throughout the winter months. Although the wintertime is the most pleasurable season to
use an outdoor hot tub, there are certain precautions you must take to ensure the proper
operation and energy efficiency of your unit.
Setting your controls: If your spa has an Auto Heat or
Freeze Protect system, make sure that it is activated as soon as the temperatures start to
drop at night. Many spas have a Timer - Auto Heat button on their control boxes. Flip the
button to the Auto Heat mode. This will ensure that the water in the spa and the jet
piping doesn't freeze.
If your spa has a Topside Thermostat Control, make sure
that it is set past the Freeze section, well into the Heat or High portion of the dial.
If your spa does not have an Auto Heat or Freeze Protect
mode, but it does have a timer system, you'll want to reset the time to give you the best
possible protection against freezing. If you have an Infinite Cycle Timer, it is a good
idea to set it to come on for 15 minutes every hour.
This will ensure good hot water circulation through the
pipes as well as keep the water nice and hot. If you have a timer that is set with brass
and silver colored pins, it is a good idea to purchase additional pins so that you can set
it to go on 15 - 30 minutes every two hours.
If your spa does not have Auto Heat, Freeze Protection or a
timer, you must keep the spa running on low speed heat mode 24 hours per day until there
is no more danger of freezing temperatures. If this is the case, you should probably call
an electrician and have him install a timer on the electric line that feeds your spa. This
will save you a lot of money !
On many spas, there is a thermostat dial on the heater unit
itself. This dial should be set at the High or Maximum position. If you find that the spa
does not stay hot enough, increase the running time. If the spa gets too hot, decrease the
thermostat setting. Do not decrease the running time !
Heating your spa: According to the electric company,
"It costs less to maintain the temperature in a controlled environment than it does
to let it get very cold and then BOOST the heat up on demand". Most outside spas
provide the ideal "controlled environment". Don't let your spa water get cold
and then CRANK the heat up right before you use it. Aside from running the risk of a
freeze up, this method of heating will cost you a tremendous amount of money in energy
bills. It is recommended to maintain your water temperature on a consistent daily basis
during the winter.
Remember...the colder it is (inside or outside), the longer
it will take for your spa to heat up. Spas must run considerably longer during the winter
to achieve the same heat rise as in the warmer months.
Draining your spa: It's no fun to have to drain and clean
your spa when it is freezing cold out ! It is a good idea to clean and refill your spa in
mid-December when the temperature is still somewhat mild. This way, the spa should not
have to be drained again until the end of February or the beginning of March - depending
on use - when the temperatures are milder once again.
Keeping the heat in: Now that you have nice fresh water,
and you have set all your controls for the maximum energy efficiency and safety, don't let
all that great heat escape ! It is strongly recommended that you use a Thermal Blanket
under your regular "hard" hot tub cover. The Thermal Blanket floats on the water
surface and caps all the water heat inside the tub. Thermal Blankets are very inexpensive
and work great!
