The SuperStor Ultra is true advancement in hot water generation. By tying the Ultra into your existing or new boiler as a seperate zone with a circulator or zone valve, it will start the boiler only when the Ultra requires hot water and transfers heated energy through the high output exchanger to produce larger amounts of hot water.
2" of insulation around tank allows less than 1/2 degree per hour heat loss; the best in the industry.
Stainless steel tank allows manufacture to offer limited lifetime protection plan (as a installer, we have never had a leaky tank or had to replace a Super Stor, ever).
Consider this, based on a full tank of 115 degree hot water, a 40 gallon electric water heater 1st hour rating is about 40 gallon. A 40 gallon gas (40,000 btu) has a 1st hour rating of about 76 gallons ((about 3 showers)) and a Super Stor SSU 45 has a 1st hour rating of 292 gallons. Thats Awesome!!! Then think about the heat loss. A typical gas or electric water heater tank has 1" of insulation and then a gas water heater has a flue with a constant draft stealing heat off of the steel tank. Now think how long a typical water heater lasts 6 - 10 years?
Stainless steel indirect water heaters with 2" of insulation, maintenance free, and a lifetime warranty is awesome and well worth the money.
