Pool Water Warmer Than Air

Experts recommend that you keep your indoor pool room heated to two to four degrees warmer than you keep the water temperature.
Pool water warmer than air. This again means the hvac system and dehumidification equipment will be under designed. Since the pool water temperature will not change that much within one or two hours the cooler air makes the water feel warmer than it was previously. Solar pool covers as well as liquid pool covers will assist in trapping the heat in the pool. The more warmth and humidity in the air the more efficient the heat pump will be.
When it comes to heat retention inground pools will stay warmer for longer because of the insulative properties of the ground surrounding the pool. Sometime the air temperature will drop even lower than the pool water. When the evening air cools down from the heat of the sun the difference between the air temperature and the pool water changes. Water evaporates at a faster rate when the air around it is cooler.
Of course this can be used with a water heater or a similar system that allows the water to be warmed. Other important factors that could affect temperature are things like water features and wind conditions. Where is the airflow directed. Because the water takes more heat from your body.
