Don't have but, desire one.

I have a Noritz tankless mounted outside and after five years it continues to be awesome. Installing the tankless turned out to be a few hundred dollars cheaper than replacing the standard one because the old one was not in a place that was allowed by new code so it would have had to be moved and the cost of relocating the standard one was very expensive.

I have a Noritz but previously had a regular water heater. I had constant problems with the traditional water heater, but no problems with the tankless. It takes up way less space too. I am very satisfied with this purchase.
