Ecotemp Dazzels

I have had an L5 tank less water heater for 5 years. It works perfect at our cabin for outdoor showers and I also use it to heat water for my kitchen sink. I see now there is a tank less heater that I could leave installed outdoors and not have to cover the heater when not in use. I live in a northern Wisconsin climate and occasionally I get caught with a frozen heater. These heaters are really a great product. I am so glade I can get buy parts for the heater.

worked better than I had anticipated

It was easy to know what I needed to order after accessing the website. Everything on the install went as smoothly as it could. I did lose the use of my red indicator light but all else works perfectly

Must have water heater

This is a must have on-demand water heater. I use mine on a remote ranch and have an outdoor shower but also have it spliced into my really old trailer that long ago lost its own water heater. Now I have hot and cold water in the trailer too. This last winter I left it outside and forgot to drain the water. It froze and the regulator cracked. No problem, I called Eccotemp, spoke to Tom ( a really good guy)and he shipped me out a replacement regulator unit at a fraction of the price of a new unit. Great service and great product!

L5 gas/water valve

Item is reasonably priced. Quick shipping. Got it installed and have hot water again. The old valve failed when the plastic disc against the water diaphragm disintegrated. I hope this new unit has an improved disc. The old valve lasted a little over 14 months.
