Frequently Asked Questions
What is the difference between this (460731) and the natural gas 200K model (460730)?
The 460731 runs on liquid propane and the 460730 runs on natural gas. All performance specifications — BTU output, cupro-nickel heat exchanger, LCD display, and 2-year warranty — are identical. Choose the LP model if you don't have natural gas service at your property.
Does this heater require professional installation?
Yes. Propane heater installation involves connecting to a propane supply line, electrical wiring, and proper venting. A licensed pool contractor or plumber must perform the installation to ensure safety, local code compliance, and warranty validity.
Is it compatible with salt water pools?
Yes. The heavy-duty cupro-nickel heat exchanger provides superior resistance to salt water corrosion.
What size pool is the 200K BTU suitable for?
As a general guideline, 200,000 BTU is typically suited for pools in the 15,000–20,000 gallon range depending on climate, desired temperature rise, and heat loss factors. A licensed pool professional can calculate the correct BTU requirement for your specific pool and location.
