I bought this system about 2 months ago and installed it myself but I'm a licensed electrician. I would definitely make sure you use a licensed electrician. This unit requires at least a 200 amp service panel, you will need a 125 amp breaker in the main panel and 3ea-50amp breakers in your sub-panel. Wire size from main panel to sub-panel will be 2 gauge and 8 gauge from sub-panel to your hot water heater. I live in the Pacific Northwest and this unit works perfect for my whole house needs. You will not be disappointed if you purchase this unit and Great Savings on my energy bill.

            Replaced 4 of these in 9 months all under warranty but not worth the hassle. Cheap Chinese plumbing and electrical components as confirmed by their staff. Pipes were stainless instead of copper. Not a good idea. Heaters developed leaks. The last one after only 1 week. If you purchase, plan to become an expert in water heater replacement.
