So I am going to replace my water heater and would like some advise.....Have a Seaward 11 gallon that has lasted 16 years and still going but not thrilled with the aluminum tank. Also, appears to be a lot of corrosion and feels moist underneath so maybe this is a good time. I like the Isotemp units (8 gallon due to space) but they have two designs; both have ss tanks but the "SPA" model has a Polypylene exterior ($542) with the "Basic" having a ss exterior ($738). Is there a real issue with a plastic exterior? It appears that all else is the same. Also they come standard with a 750 watt coil however can upgrade to $1,200 watt. My Seaward has a 1500 watt coil.
Would love to hear from experienced users..........
Thanks
