Pentair MasterTemp Gas Pool HeaterDespite its functionality this pool heater is compact. It measures only 21″ x 21″ x 28″ (L x W x H) so is easy to install even where space is limited. A rotating digital display ensures that the controls are easy to see and use regardless of how the heater is positioned. The cabinet is a tough composite material which is not affected by heat or the weather.

However, the key selling points are:

  • It is certified for low NOx emissions so can be used where NOx emission restrictions are enforced.
  • It has an efficiency rating of 84% (using the standard copper heat exchanger) making it one of the cheapest to run gas heaters.
  • Heats up fast due to its fully pre-mixed system – which also contributes to its efficiency – so no waiting around for your pool to heat up.
  • Easy to operate – required temperatures can be set at the touch of a button and a digital display shows the water temperature, whilst five LEDs show you what is going on.

There are also two “heavy duty” models which use a cupro-nickel heat exchanger. This stands up better to heavy use and poor pool chemistry but reduces the efficiency to 82%. ASME versions are also available for commercial use.

The Pentair MasterTemp heaters have a series of features designed to ensure safe operation but you can’t please everybody. For instance there is a factory set maximum water temperature which annoys some users (there are discussions online about how to get round this). However, overall this heater is a good choice if you need a low NOx gas heater.
