California's Title 24 is a California swimming pool code impacting the pool and spa industry by mandating higher energy efficiency, requiring renewable/electric heating (like heat pumps) over gas for new pools/renovations after 2026, setting strict pool control standards (like timers, smart features) for efficiency, and adding safety rules (like barriers) for residential pools. The industry must adapt to these evolving standards for construction, equipment, and operation to ensure compliance, focusing on reduced energy use and enhanced safety.
Quick Summary:
- Gas heaters alone are no longer allowed for new or newly heated pools
- Heat pumps and solar heating are the preferred options
- Gas heaters are still allowed, but only as secondary (backup) heat
- Variable-speed pumps are required
- Single-speed pumps and motors are being phased out
- All equipment must be Title 20 / Title 24 compliant
Pool & Spa Heaters: What’s Allowed vs. Not Allowed
ALLOWED POOL & SPA HEATERS (Title 24 Compliant)
These heating options meet California’s 2026 energy standards:
Heat Pump Pool Heaters (Primary Heating):
- High-efficiency electric heaters
- Can serve as the main heating source
- Lower operating costs over time
- Fully Title 24 compliant on their own
Solar Pool Heating Systems:
- Uses rooftop solar collectors
- Must cover: 60% of pool surface area (residential), 65% (public/commercial pools)
- Proven, long-term compliant solution
Hybrid Systems (Best of Both Worlds):
- Heat pump + gas heater
- Solar + gas heater
- Solar + heat pump
- Gas heater acts as supplemental / backup only
Gas Heaters (With Restrictions)
- Gas heaters are still allowed if: They are NOT the primary heat source
- Paired with: Solar heating, or A heat pump, or On-site renewable energy (e.g., solar PV supplying ≥60% of annual energy)
- No continuously burning pilot light is used
NOT ALLOWED UNDER TITLE 24 (2026)
- These setups do not comply with new installations or newly heated pools:
- Gas heater as the only heating source
- Electric resistance heaters used alone
- Gas heaters with continuous pilot lights
- Non-certified heaters not listed in the MAEDbS database
-
Existing pools are often grandfathered, but new installs or upgrades trigger compliance
Pool Pumps & Pump Motors: What’s Allowed vs. Not Allowed in California Swimming Pool Code
ALLOWED POOL PUMPS & MOTORS
Variable-Speed Pool Pumps (Required):
- Automatically adjust speed for efficiency
- Must default to low-speed filtration
- Reduce electricity usage dramatically
- Required for: New pools, Replacement pumps, Many remodels
Title 20-Certified Pump Motors:
- Replacement motors from 0–5 total horsepower (THP) must comply
- Must meet DOE and California efficiency standards
- Must be listed in the Modernized Appliance Efficiency Database (MAEDbS)
NOT ALLOWED PUMPS & MOTORS
- Single-speed pool pumps
- Non-certified replacement motors
- Oversized pumps that exceed flow limits
- Pumps without proper time-switch or control functionality
- California is phasing out inefficient motors entirely between 2025–2027, depending on horsepower
Do These Rules Apply to My Pool?
Title 24 Typically Applies If You Are:

- Adding heating to an existing pool
Title 24 Usually Does NOT Apply If You Are:
- Repairing existing equipment only
- Replacing parts without changing the system type
- Using a portable electric spa (Title 20 compliant)
