How Heat Recovery Works
Unlike units equipped with a 4kW electric heater built into the system the heat recovery system has been developed to make use of
heat generated from the hot tub pump motor. Water passes through a heat jacket wrapped around the outside of the pump motor
collecting the natural heat generated by the motor and recycling that heat back into the hot tub.
For this reason it is important to know that the mechanics in a heat recovery system are different from a separate heating system and
therefore; you hot tub will demonstrate some distinct difference. Listed below are some of the difference you should account for:
1.
Your hot tub motor will only have one speed, “high speed.” Do not be concerned that your hot tub seems to run
constantly until your desired water temperature is reached. In most cases your hot tub will reach a desired temperature in
approximately 24 hours. Depending on your start-up water temperature and the temperature you have programmed.
After your desired temperature has been reached your hot tub will cycle on and off to maintain temperature.
2.
Your hot tub is equipped with an automatic filtration system. The filtration system is set from the factory to cycle every
12 hours. If your hot tub filtration cycle is starting at an awkward time of the night we suggest you plug your tub in at a
time where the 12 hour filtration will activate at an appropriate time. For example, if you plug in your tub at 8:00 pm the
next filtration cycle will begin at 8:00 am. Whereas, plugging the unit in at 3:00 pm will cause the filtration system to
start at 3:00 am.
3.
Your filtration cycle can be changed to operate more frequently than every 12 hours. It is possible for your hot tub to
register a higher temperature then what you have set it for, if your filtration system is operating frequently. Keep in
mind that a heat recovery system heats the water whenever the motor is running and therefore, a filtration period will
heat your water when it is activated. If you have set your water temperature to 100 degrees and the topside reads 102
you may need to reset your filtration cycle to a program which activates less often.
4.
If your hot tub seems to be loosing temperature or not heating check to make sure your cover is on.
Frequently Asked Questions
Q.
I have noticed water on the outside of my hot tub- is my hot tub leaking?
A.
A small puddle of water around the outside of your hot tub can be produced by water collecting and
rolling off of your cover. Check to see if the water is coming off of your cover. This is normal. If this
is not the problem you may want to call your dealer and have a technician come out and examine your
fittings.
Q.
My hot tub seems to be running all the time, is this normal?
A.
This is not a problem with your spa. There are a few reasons why your spa will run through out the day.
1.
Your spa checks the temperature of water approximately every 20 minutes. In order to have a correct
temperature it circulates the water in your tub for approximately 3 minutes.
2.
Should the spa pack determine the temperature in your spa has changed an adjustment will be made by
the spa pack, in most cases a temperature loss is indicated and therefore, the pack will turn on the
heating element for whatever duration is necessary. In the case of a heat recovery pack the motor will
run producing heat for your hot tub water until it reaches temperature.
3.
Depending on your Volts Alternating Current or VAC your hot tub will heat at either 1kW (110VAC)
or 4kW (220VAC). The duration of heating time will change depending on the VAC supplied to your
hot tub.
4.
In addition to checking water temperature, your hot tub is pre-programmed to circulate the water for
filtration. It is possible for your hot tub to take a temperature reading and go into a filtration cycle at
the same time. Typically, your filtration cycles occur twice a day.
Q.
My hot tub motor does not shut off when I push the button to turn the motor off?
A.
Many hot tub user turn off their hot tub when exiting, however; it is important to know—your hot tub
motor must be running in order to heat the water (standard 1kW-4kW element or heat recovery),
therefore; your hot tub may continue to run if the temperature in your hot tub has dropped below the set
temperature. Heating your hot tub water overrides your ability to turn off your hot tub motor.
