I have been browsing and can't believe how many companies are out there...prices ranging from $275- $1100. The specs don't look much different and the only difference I can see are the warrenties. E-tankless has the best life time for everything, pricing about $600 for a full house two showers at the same time. But Niagra has a model for $275...close to the same specs. All are 240 single phase and have 2 to 3 40 amp breakers.
Any advice and write ups on these and or other similar products?
