I am used to swimming in friends' pools who have traditional gas/propane/electric element heaters where the water simply passes through a hot element of some sort and returns to the pool warmer than it left it. when you feel the jets/returns in these pools the water feels significantly warmer than the surrounding water when the heater is on. Now i have a pool of my own after recently purchasing a house. It has a hayward heatpro titanium heat exchanger 110k btu model hp21104t. I turned it on for the first time today and i noticed that the water coming out of the jets is barely any warmer than the pool water. is this normal? its about 75 degrees outside and my pool is about 67 degrees. i had it set to 90 just for testing purposes. is this normal performance for a heat exchanger? i'm not complaining that it isn't heating the water fast enough in the pool, i'm just curious as to how it can even heat the pool if the water coming out of it is barely warmer than the water leaving the pool? FWIW, the heat exchanger read a temperature of 69 deg, the SWG (downstream from heat exchanger) read a temperature of 70. I understand how a heat exchanger works, as it is basically just an air conditioner in reverse. the pool water runs through the condenser and the refrigerant that is 'cooled' by the pool water absorbs heat from the air at the evaporator. i know they do not heat as quickly as gas/element heaters but i imagine that the water should be more than a degree warmer than the pool water.
Side note, when i first turned it on the fan wouldn't turn on. i called hayward and they said either my fan motor is bad or that the motor is not getting voltage. i take off the front panel to see that one of the wires on the board going to fan was CUT. anyway i fixed it and it fired right up. the compressor was working as i could hear the relay.
