New Pentair ETi 250 Heater for a smaller inground residential pool
Installed just over a week ago, it's already been used a fair bit for an indoor 45,000 liter (12,000 gallon) salt water pool in southern Ontario. Specialized unit (reportedly commercial grade with a titanium heater exchanger), so its a bit pricey, but there are not a lot of options out there for an indoor residential pool. Thankfully, it was on sale. We got 12 years out of our last heater (different brand). Its quiet, sleek, simple to operate, and reportedly has 96+ efficiency (meaning that 96 cents of every dollar spent on natural gas goes into heating the water). The temperature read and preset features are very convenient. Its still early days, but so far its working great! Many thanks to William for the quick turnaround on the unit, and also to our installer Charlie, both were very professional.
