Frequently Asked Questions
What does HD mean on a MasterTemp?
HD is the heavy duty version, built with a cupro-nickel heat exchanger instead of copper. It handles saltwater, low pH, high flow, and generally harsher water chemistry.
Should I buy the 460806 HD or the standard 460732?
Choose the HD if you run a saltwater pool, your water chemistry swings, or you have had a heat exchanger fail before. The standard 460732 is the better value on typical residential water.
Is the 460806 natural gas or propane?
Natural gas. Fuel is set by model.
What size pool does 250,000 BTU 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.
Should I step up to the 400HD?
The 460805 is the 400K BTU HD model. Go bigger if you have a large pool, a spa you want hot quickly, or a colder climate where recovery time matters.
Is it Low NOx compliant?
Yes. MasterTemp heaters are Low NOx certified, which is required in California and other regulated air quality districts.
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.
