Frequently Asked Questions
What size pool does a 250,000 BTU heater suit?
Larger in-ground pools and pool and spa combinations. Sizing depends on surface area, temperature rise, and climate, so have a pool professional size it for your install.
Is the 460732 natural gas or propane?
Natural gas. Fuel is set by model. Order 460733 for the 250K BTU propane version.
Should I choose 250K or 400K BTU?
250K covers most medium to large pools on a normal schedule. Step to the 460736 at 400K if you want faster spa recovery or you are in a colder climate.
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. The 460806 is the 250K HD version. Standard models like this one use copper and suit typical residential water chemistry.
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 status notifications.
Does it need professional installation?
Yes. Gas sizing, venting, electrical, and local code make this a licensed installer job, and improper installation can affect warranty coverage.
