The MasterTemp 125 is Pentair’s low NOx gas pool heater for smaller installations, including above-ground pools, spas and in-ground pools up to 15,000 gallons. Their aim is to deliver the sort of energy efficiency and advanced operating features that were previously available only on larger, more expensive, models.
There are just two versions, one for natural gas and one for propane. To purchase a Pentair MasterTemp 125 from Pool Supply World – Click Here
As its name suggests the heater is rated at 125 BTU and is 82% efficient. This level of efficiency is possible due to its “pre-mixed combustion technology” which also enables fast heat-up. The heater weighs only 80lbs which together with its compact size makes it easy to install where required. It requires a 3/4″ gas line and a standard electricity supply. Plumbing connections are 1-1/2″.

The heater features a digital display/controller which rotates if required to provide easy access for programming and monitoring.
Price wise it is slightly more expensive than the MiniMax model it replaces but it is more powerful and has more features.
Heaters aimed at this market have not generally had rave reviews and it is therefore interesting that Pentair have chosen to market this as the baby brother of their successful MasterTemp model range. Hopefully this means that they are confident that it will be reliable.
Even though this heater has been available fora few years now, there are not a great many user reviews out there. Hopefully this means that most buyers are happy with it, we will have to wait a bit longer to find out.
