    • Works well for above ground pool.
Works great for keeping my 10ft Intex above ground pool at 90 degrees. Took off a star for unlabeled wires (color is not standard for USA) and a pressure sensor that would work much better with a lower pressure level.

    • Water pressure cutoff switch ... demands too much pressure for such a tiny heater.
Not a bad tiny heater for the price. I am using it to take the chill out of my 14x36 above ground pool. It's not going to turn my pool into a spa! But it does makes it alot more comfortable to enter the pool. In 24 hours it increased the temp by 4°. There was a problem at first because of the water pressure sensor cutoff switch. (If the pressures isn't at a specific flow ... heater won't start). Easy fix ... had my electrician bypass that switch ... now the heater does the job I purchased it for. ... show more

    • heater
The unit does not use American standard fittings on both ends and you will need to find a way to adapt it. So you will need to use 1 1/2 neoprene adaptors to make it work. The adaptors can clamp to the outside of the fittings on the unit.

    • Did not work
This heater never worked, the light turns on and looks like is working but it doesn't heat the pool, I installed it a small above ground pool, left it on for over 24 hours and and the water temperature didn't raise at all, Waste of my money an time :(

    • PVC size didn’t match up
The only problem was the pvc size wasn’t an exact match (a bit smaller), which was an easy fix, but a bit of a hassle.
