Pool Heater Not Heating in Chula Vista, CA
Pool Heater Not Heating is one of the more common calls we get from Chula Vista homeowners. No heat, short cycling, or an error code usually points to ignition, gas or airflow, or a scaled heat exchanger. Chula Vista runs on Sweetwater Authority / Otay Water District at 12-16 gpg, which is hard water. Around here that means a split market of aging west-side plumbing and hard-water equipment strain out east, and it shows up in problems exactly like this one.
Likely causes in Chula Vista
- Failed igniter, flame sensor, or pressure switch
- Insufficient water flow tripping the high-limit
- Scale buildup inside the heat exchanger from hard water
- Gas supply or valve problem on a gas heater
- A failing control board on an older unit
What to check before you call
- Confirm the pump is running and flow is strong
- Check the thermostat is set above current water temperature
- Look for an error code on the display and note it
- Clear leaves and debris from around the heater intake
