Our Experience With the Product

I am totally impressed, or you can say obsessed, with this water heater because it doesn’t make any sound while heating the water.

It works so silently. Within 1-2 minutes, I get hot water from the tap.

The only problem that I faced after installing this water heater was that the heater requires 80 amps for heating the water, and we have got 100 amps of electric service in our home.

So, if you have got 100 amps or less electric service, then you shouldn’t buy this product.

Overall it is a good product but only messes up when it comes to consuming electricity.
