    Comments about Reliance Sta-Kleen 1212 Series Tall Gas Water Heater:

    Best warranty I found on a water heater. Chose this unit from Abt over certain other brands as only option by several local plumbers. Researched these brands and found on their website pitches to plumbers for discounts and marketing, but not much evidence of better value, performance, time in service over basic units from big box discount retailers. Most of these offer only 6 yr warranty with option for 9 yr for more money for essentially the same unit (seems like road hazard insurance on tires). This Reliance hot water heater unit is built of thicker steel from what I can tell, has unique design features like inlet that limits sediment accumulation, special tank anti-corrosion lining. Price was excellent, installed with all fees, this deluxe unit did not cost any more than quotes from 3 other plumbers for a basic model of another brand, installed.

    Service and delivery comments:

    Slight problem confirming the time and date, but quickly fixed, Abt and installers went above and beyond to make everything right. The installers were quick, professional and made all connections with skill and care.
