    Customers are mixed about the heating of the electronic component. Some mention that it keeps water hot, heats 300 gallons of tap water at about 2 degrees per hour, and a constant water flow activates the heater. Others say that the product didn't heat when received, it will not heat up cold water quick, and the heating element has failed.

    3 customers mention0 positive3 negative

    Customers are dissatisfied with the pressure switch in the electronic component. They mention that it takes a pretty hefty pressure to get the element to activate, and that it expects more psi than is typically seen in a unit. Some reviewers also mention that the switch is faulty and needs to be replaced.

    "...Additionally, the internal pressure switch takes a pretty hefty pressure to get the element to activate (turn on)...." Read more

    "...using this outside of a spa situation should know - the pressure switch does expect more psi than is typically seen in a pool filter pump return..." Read more

    "...I ended up pulling the unit apart and replacing the faulty pressure switch to make it work." Read more

    Works great so far.
    This thing is everything I hoped it would be. Works as advertised. Quite a bit bigger than I'd anticipated, but that's a good thing.I used this as a replacement heater for my mini hot tub and it heated 240 gallons of water to 104° in about 24 hours. As you can see it comes with several different sized attachments for various pipe sizes. I connected it to standard 1-1/2" pvc pipe that I got at Lowes.Nothing bad to say so far. I'll update if/when it ever dies.My only gripe is that I had to wait for it, but they probably build them as needed. Not enough to take a star off.
