Frequently Asked Questions
What size pool does a 200,000 BTU heater suit?
It fits mid-size pools and pool and spa combinations. 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 460731 propane or natural gas?
Liquid propane. Fuel is set by model. Order 460730 for the 200K 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.
Is the Smart Heater Bypass Valve Kit worth adding?
It diverts water around the heater when heating is not called for, which reduces flow restriction and pump load. Pentair rates the savings at up to 35% of annual operating cost. It is sold separately.
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.
