    Looking for a Pro with Dectron Experience

    Just purchased a home in North Idaho with an indoor pool/spa. Both have covers. We have a Dectron Dry-O-Tron system which appears to be installed well with air outlets under all the windows. We have no problems with condensation but I need some help with understanding how things work, with settings that will lower overall energy costs and finding someone to maintain the pool and Dectron unit.

    Thanks!

    Dectron is a good system but must be maintained by an experienced person. Depending on the series system you have equates to the functions possible with that system.

    It most likely dehumidifies you indoor pool area first and foremost, it also has control over the room temperature and, depending on the model, it uses the energy used to dehumidify the pool room space to heat the pool water. You can also have different features including an Air Conditioning mode.

    The system must be on all the time. The fan must run all the time. And if you want to save energy the pool must be covered when not used. If attached to your home the pool room must be in a slight negative pressure to assist in keeping the chemicals/humidity from entering your home.

    The pool room temperature should be set about 2 degrees higher than the pool water temperature to create a thermal block when the cover is off. And the humidity should be in the 55% to 60% range along with keeping an eye on the room/walls to make sure condensation is not building up.

    The air filters need to be kept spotless. And, once again, someone with experience needs to maintain the system. If the system fails call your service person right away. Do not wait as moisture can build up in places where moisture can do a lot of damage in a short period of time.

    Maybe a steam humidifier would be appropriate with the cover on,

    to assure the Dectron unit had plenty of work to do.

    At least the pool chemistry would be more stable.

    With a pool cover installed there is less humidity to remove. Plus the pool covered also indicated the pool is not being used so no "splashing" of water by the occupants is taking place. That "splashing" is where a lot of the humidity in the air comes from.

    And with the pool cover on there is less load on the dehumidifier/heat pump so it will operated less, have less humidity to remove and have a more stable thermal barrier between the pool water temperature and air.

    Customers can save a lot of money and wear and tear on their systems by covering their indoor, as well as their outdoor, pools with a cover when not used.
