The media could not be loaded. I live in upstate NY. We have decent summers but most evenings we drop down to mid 60° to high 50's. I purchased this for my inflatable hot tub. The hot tub heater works, but about 10-15 minutes later the temperature drops 6°. I've used the heater every night and my hot tub stays at 104° with this heater! This is the best investment I've made all summer!

I have an above ground 12x18 foot pool. It is the end of September in Kansas and I am trying to keep my pool up as long as possible. I tried another heater, and it sucked and lasted 2 days. This one gets much hotter and has warmed my pool from 77 to 87 degrees (with the addition of a 16 mil thick solar cover.) I am so happy with the quality, effectiveness and price!

Heater works great for reheating my inflatable hot tub. Unfortunately the factory heater stopped working. Perfect replacement. Better than factory. It will get unbearable hot if you do not use the digital meter/regulator. Would recommend for same issue or similar applications. ⭐️⭐️⭐️⭐️⭐️
