NEED TO HEAT AN INDOOR POOL, DO I HAVE TO PUT IN A DEHUMIDIFICATION UNIT, THERE IS AN EXHOUST FAN IN THE POOL AREA. WHAT IS THE BEST WAY TO HEAT THIS AREA?
Heating the water elsewhere and pumping to the pool willl give good uniformity of temperature. By exhausting sufficient amount of air (to remove extra moisture) you can maintain the area condition. But there will be heat loss from the system and your energy bill increases. If you want I can provide you with an equation for the rate of moisture addition to the area.
