Buderus' Thermoglaze process protects the interior of the horizontal standing ST Series tank from corrosion caused by most water types. Thermoglaze is a homogeneous, permanent protective coating, bonded to the interior of the metal tank. The large surface area heat exchanger allows for excellent recovery rates; heat exchanger increases with tank volume. The high density fluro-carbon free bonded foam insulation maximizes the protection against heat and temperature loss. The ST Series' optional recirculation of hot water provides instant hot water at the turn of the tap. It has an easy access cover for cleaning of the coil and tank interior, standard magnesium anode rod for active corrosion protection, and adapts readily to the Buderus Logamatic Control.
Long Term Dependability
The average life span of Indirect Fired Water Heater exceeds 20 years! That is two or three times the average life of a conventional gas, oil or electric water heater.
Superior Heat Exchange Surface Area
Large surface area heat exchanger for excellent recovery rates.
Stainless Steel Tank Construction
The inner domestic storage tank is constructed of durable, corrosion resistant stainless steel.
High density fluoro-carbon free bonded-foam insulation, resulting in a stand by heat loss of less than 1�/Hr.
Self Cleaning / Self - descaling
The inner, domestic tank is suspended within the outer tank so it is free to expand and contract as the pressure varies during hot water draws. Moreover, its corrugations amplify the movement and prevents the lime build up on the heat exchanger; thus maintaining its performance during the Ultra Series life span.
The Buderus Thermoglaze� process protects the interior of the tank from corrosion caused by most types of water.
Other Standard Features :
Product Warranty: 1 year parts / Limited lifetime heat exchanger
NOTE: ALL TANKS REQUIRE AN AQUASTAT TO BE PURCHASED EXCEPT FOR THE S-120...
