Hello,
We opened our pool last July and ran it through mid-November. We had the pool as hot as 95 degrees in 35 degree weather. We opened first of this month and pool heated from 48 degrees to 85 degrees in about 24 hours. All of the sudden, the heater won't heat.
Pool builder/HVAC/plumber are at a loss for what is going on. Temperature sensor seemed bad, as heater thought the pool was 95 degrees when it was only 65. So if I cranked up temp past 95, it would kick back on. But even then, the water coming out of the return jet was barely warmer than regular water, whereas last season, the return jet water was super hot to the touch. They fixed this sensor/thermostat and it is now reading correct temp. They also said there wasn't enough gas getting to the unit so they changed a flexible pipe to a straight pipe and a gas regulator (didn't make sense to me b/c it all of the sudden went bad).
So anyway, they say it isn't throwing off any error codes and at 10am today they had it all running and they thought it was good to go. It's been running since 10am (9+ hours) and it has only gone from 68 to 72 degrees, and the water coming out of the return jets remains lukewarm at best. From online calculators, this heater should heat my pool up 1 degree every 37 minutes, so it should have gone to at least 82 degrees by now. The heater is still firing, exhaust is very hot, thermostat/temp sensor works, but the water isn't getting heated. Water isn't bypassing heater, as the only return jet pipes go through the heater.
Please help, as my pool builder is out of ideas. I'm wanting to swap the unit out entirely for warranty, but if there's a quick fix, I'm all ears.
Thanks in advance.
