Natural gas and LPG models are available. Everything looks perfect, but customers warn that the unit is a low power one, for small pools only. Beside some complaints about plastic cabinet, there are remarks that heating is much slower than expected... or the users have had unrealistic expectations.
The other MasterTemp units come with more power – from 175K to 400K of BTUs and prices from $1800 to $2200. All Pentair pool heaters are available in natural gas and LPG option, and utilizing HD cupro-nickel heat exchanger option instead of copper heat exchanger built-in standard models.

There are natural gas and LPG models with standard (copper) or heavy-duty (cupro-nickel) heat exchanger. Users have evidenced in their online reviews features they love – remote control and dual thermostat. One of the minor complaints is vertical plumbing fixtures for water supplies.
