Product details

The Pentair MasterTemp 460736 is the 400 BTU natural gas pool heater in Low NOx form, rated in the 350,000 to 400,000 BTU band. It is the largest heater in the residential MasterTemp line.

Running it

The MasterTemp is meant to be as easy to live with as a home heating system. Digital temperature control sets the target, and the indicator lights on the panel make it obvious at a glance whether the heater is calling, firing or satisfied. Electronic ignition means there is no standing pilot to relight when the season starts.

Build

Heat moves through a copper heat exchanger, and the whole unit is built compact and quiet enough that it does not intrude on time at the pool. It is intended for inground residential pools and meets Low NOx emission requirements.

Before you order

This is the natural gas version. Confirm your gas supply and line sizing suit a 400 BTU appliance, and note that the heater ships by freight.

Questions and answers

What people ask about this product, answered by our pool techs.

What size is this heater?
It is the 400 BTU MasterTemp, rated in the 350,000 to 400,000 BTU band, the largest in the residential line.
Does it run on propane?
No. This is the natural gas model. Pentair builds the MasterTemp in propane versions under different part numbers.
Is there a pilot light to relight?
No. It uses electronic ignition, so there is no standing pilot.
How does it ship?
By freight. A 400 BTU heater is too large and heavy for parcel carriers, so plan on a curbside delivery.
