Just got my pool completed and had a Rheem gas heater installed. Ran it today and it is saying my water is heating but it’s not. The pool water temp goes from 75 to 90 in about an hour per the display but the actual water temp never moves from 71 or so. I’ve tried to restart the system but it still does it. Any help would be great I already contacted the pool company but it’s the weekend plus I want to be knowledgeable about it when they finally come. Any help would be greatly appreciated.

How are you measuring the actual water temperature?
What displays are you looking at for what?
If your gas heater is running then the heat is going into the water.

I just had a pool put in and had a heater installed, the heater is saying the water is hotter than what it actually is. Set the heater to 88 and it will go from 70 to 88 in an hour but the actual temp in the pool is 71. Any help would help so when the guys come to fix it they can blow smoke at me.

Please put the number of gallons in your pool in your signature.
Your heater can only heat your pool 1 to 2 degrees an hour.
Post a pic of the display saying your pool is 88.

I don't have a Rheem heater but looks correct. Maybe the folks with Rheems can verify the in and out are correct
Maybe an issue with the heater, they should fix it what ever the cause for free
Let me know what they find, sounds like the sensor isn't getting water flow.
I am waiting for the pool company to call me back but I am sure they will take their sweet time in getting back to me.
The inlet and outlet should be marked with arrows or the words inlet and outlet.
Which is the inlet and which is the outlet?
What is the pump speed?
What is the filter pressure?

Input on left, output on right. Looks correct for OP.

Inlet is the one in front has an arrow pointing towards the heater.
I have tried all pump speeds highest to lowest that the heater would run on.
Pressure in between 10 and 25 depending on pump speed.

Did you post a picture of the display when it shows how for Allen? Somebody with that heater may see something
Are you sure that the gauge is good? It looks weird.
Can you verify that the flow is good?
Have you backwashed the filter?
What is the exact model of the heater?
Are there any error codes?
Note: You should never leave the pump off when you have tabs in the feeder because the chlorine will destroy the heater.

Yes, there should be a check valve.
However, even with a check valve, the chlorine is so corrosive it will damage anything it can get to, including the check valve.
Tab feeders are bad news when the pump is off.
Didn’t post a pic of the gauge I turned the heater off cause it’s just wasting money on gas at this point.
Raypak technician came out and changed the thermostat everything is up and running now. Thank you everyone for your input and advice.
