Our take on the Ruud Avia Natural Gas Low NOx Pool and Spa Heater 264K BTU

The Ruud Avia is a natural gas pool and spa heater rated at 264,000 BTU with a low-NOx burner and 84% thermal efficiency. It uses a polymer header and cabinet to resist corrosion from pool chemistry, and it needs a 4-inch flue and a 3/4-inch gas line. At $2,839 at PoolSuppy4Less as of November 7, 2026, it sits at the low end of its recent range across the three stores that carry it.

Pros
  • 264,000 BTU heats a mid-size pool quickly
  • Low-NOx burner meets many regional air-quality rules
  • 84% thermal efficiency is solid for a gas pool heater
  • Polymer header and cabinet resist salt and chemical corrosion
  • Runs on 120V or 240V with only 1.2 amps draw
  • CSA and ANSI certified
Cons
  • Natural gas only; no propane version
  • Needs a 4-inch flue and proper venting, which limits placement
  • 135 pounds and about 32 inches wide, so it is not a one-person install
  • Low-NOx units can be pickier about gas pressure and airflow

What reviewers say

Owners of Ruud and Rheem gas heaters in this family generally report fast heat-up and few problems when the unit is sized and vented correctly. Complaints tend to center on installer setup and on corrosion or sensor faults in older units rather than the heater itself.

What people mention
  • Heat-up speedPraisedOwners say the 264K BTU output warms a mid-size pool in a few hours rather than a day.
  • NoisePraisedReviewers describe it as quiet for a gas heater, with the blower barely audible from the house.
  • CorrosionMixedThe polymer header resists salt and chemicals, but some owners report rust on cabinet fasteners over time.
  • InstallationCriticisedSeveral complaints trace back to venting and gas-pressure setup, which the manual says must be done by a licensed installer.
  • ReliabilityMixedMany units run for years without issue, while some owners report failed sensors or pressure switches.

Questions and answers

Is this heater worth it over a cheaper 200K BTU unit?
If your pool is around 20,000 to 25,000 gallons, the extra 64,000 BTU cuts heat-up time noticeably. For a small pool or spa, a smaller unit saves money.
Does it work with propane?
No. This is the natural gas model. Ruud sells separate propane versions, and converting this one is not a field kit.
What size gas line and vent does it need?
A 3/4-inch gas connection and a 4-inch flue. Undersized gas pipe is the most common cause of ignition problems on these heaters.
How much electricity does it use?
Very little. It draws about 1.2 amps at 120V or 240V, so it can share a standard circuit with the pool pump controls.
When is the price lowest?
Pool heater prices tend to dip in late fall and winter, outside swim season. At $2,839 as of November 7, 2026, it is already near the bottom of its recent range.
Where is the Ruud Avia Natural Gas Low NOx Pool and Spa Heater 264K BTU cheapest?
