    We live in Louisiana. We were hoping that this would solve our hot water quantity problem. It did not. Half the time it does not work. Went over ALL the trouble shooting guides, which there are many and still did not solve problem. This has turned out to be less reliable than our original hot water heater. At least with the traditional hot water heater you have water to start. With this tankless one, sometimes it worked and sometimes it did not. Very disappointed.

How many amps does your electrical service need to install and operate these electric water heaters. I've been told that the average home (running 2 or 3 appliances at a time) will have to make an expensive upgrade to make them usable. What do I need to switch over to a tankless heater wicked49 on Mar 1, 2014

If it's a limited warranty what does that mean because the website that I found on the heating system says it's one year on electronics and 10 years on the actual part of the water flows kjkorns on Dec 12, 2012
