The Buderus Thermoglaze® Hot Water Advantage

In North America the average household spends

around 30% of energy costs on their domestic

hot water. With this in mind Buderus designs its

hot water tanks to work more economically and

efficiently. Buderus pioneered new methods of

producing and storing domestic hot water,

so you are assured of greater operating

efficiencies, lower fuel consumption and

consistent hot water, all while saving money.

Buderus’ patented Thermoglaze® is a ceramic material which is thermally bonded

to the internal components of the tank to provide a glass-like coating. This unique

coating protects against the corrosive affects of minerals that naturally appear in

water, maximizing the life of the tank, while minimizing the number of service calls.

Constructed of the highest quality materials, including the Thermoglaze® coating

on all the interior surfaces, Buderus tanks also have excellent insulation resulting in

less than a ¼°F loss of heat per hour. The larger surface area of the heat exchanger

in a Buderus tank delivers excellent recovery rates.
