Frequently Asked Questions
What size pool does a 250,000 BTU heater suit?
It suits larger in-ground pools and pool and spa combinations that need faster recovery. Sizing depends on surface area, the temperature rise you want, and your climate, so have a pool professional size it for your install.
Is the 460733 propane or natural gas?
Liquid propane. Fuel is set by model. Order 460732 for the 250K BTU natural gas version.
Is the MasterTemp Low NOx compliant?
Yes. MasterTemp heaters are Low NOx certified, which is required in California and other regulated air quality districts.
Does it work with pool automation?
Yes. It integrates with Pentair automation systems for remote temperature control, scheduling, and push notifications on heater status.
Should I choose 250K or 400K BTU?
Go with 250K for a medium to large pool on a normal heating schedule. Step up to 400K if you have a large pool, a spa you want hot quickly, or a cold climate where recovery time matters.
What is the difference between MasterTemp and MasterTemp HD?
HD models use a cupro-nickel heat exchanger for saltwater, low pH, and high flow conditions. Standard models use copper and suit typical residential water chemistry.
Does it need professional installation?
Yes. Propane sizing, venting, electrical, and local code make this a licensed installer job, and improper installation can affect warranty coverage.
