Product Description

Pentair MasterTemp 125,000 BTU Heater - 461059 is designed for smaller bodies of water such as above-ground pools up to 15,000 gallons of water.  It comes with all of the great features found on larger in-ground pool heaters and has the highest efficiency of any heater in its class at 83%.  The digital display is easy to use and has a information-rich display and control pad.  The display can also be rotated to place it front and center for any installation orientation.  This model includes a 110 Volt cord for easier installation for those that do not want to hard-wire the heater.

The MasterTemp heater is engineered for super-quiet operation and won’t intrude on your poolside leisure time.  A tough, rustproof composite exterior handles the heat and weathers the elements.

Safe operation is assured through a series of features, including; a water pressure switch that senses the pump is running to prevent overheating; high limit switches assure the heater turns off if water temperature exceeds factory set limits; manual gas shut-off when service is required; stack flue sensor also guards against overheating.

Compare energy efficiency ratings and you’ll find MasterTemp heater at the top of the list.  Comfort and economy can go together.  With a hot surface ignition (no pilot light) and push-button, digital controls, MasterTemp is as easy to operate as your home heating system.  Plus, user-friendly indicator lights make system operation and monitoring a snap.
