I had a tankless heater installed last year after finding out the new tanks were too big for my crawl space. My house has 2 closets I was unwilling to give up.

The first tankless heater was installed and it was a nightmare as I had too have a second electrical box installed to handle it which was quite expensive. The water heater worked a short time then began to fluctuates in temp. The line was flushed then flushed again. It got worse I finally insisted on a replacement and before it was available the other once popped and made a huge flash spark and smelled hot. Turned it off and shut off the breaker. It fried the internal fuse on the water heater.

Got the second one installed which was not cheap as it took electricians several hours to repair the electrical line and replaced fried areas. Was without hot water for a very long week. The new one is having temp fluctuations...right away. What more can I do?
