Customer Review: Great for the value
Summary: 5 Stars
I have a 100A service breaker in my house and this thing is fine. Sure my wires might overheat sometimes, but for the amount of time you are going to be heating water, there will be plenty of time for the wire to cool. If the wires heat too much then the breaker trips. Do the research yourself and take the advice from electricians to heart. Just be sensible about your power usage when heating water. As for failures, some people may have had failures due to not installing an expansion tank that allows the pressure increase created by heating water to be absorbed. Come on, you can replace this thing every 4 years and still save money over the tank water heaters. I have had this unit for 7 years and it has paid itself off many times more.
Another competitor to tankless is the heat pump assisted water heater. How many times has your air conditioner broken? The heat pump is essentially an air conditioner strapped onto a tank. Tons of moving parts and things that can go wrong. The corporations want you on a determined replacement cycle that they have factored into their business model. Go with TANKLESS anywhere, gas or electric, with only one moving part (a small flow sensor that detects when you need hot water). Do the calculations, yes the heat pump assisted units have high COF energy factors (2 or more), but you are still heating water all of the time during the night when you do not need it and using more electricity. If you are concerned about the electric tankless, then go with gas tankless, either way go TANKLESS. Do the math and you will find out that these heat pump assisted units add complexity and ridiculous amounts of failure points. All my tankless has is two 7,000 W heating elements, two 1/4 gallon tanks, one flowmeter and one logic board coated in epoxy to reduce failure (someone has commented that this fails so worst case, just replace the logic board). Gas tankless units are similar in efficiency and reliability, instead having a boiler to heat the water. NO moving parts = RELIABILITY.
