Indirect Fired Water Heaters

ATI designs pump mounted indirect fired volume water heaters with extended life expectancies when properly maintained. Components may wear out, however, repair of these components costs substantially less than a new tank type water heater. Tank-type water heaters are “disposable” pieces of equipment that are frequently replaced.

Indirect fired volume water heaters are designed to operate scale-free, even when used in hard water areas. Tank-type water heaters can operate scale-free only if all the calcium and magnesium carbonate are removed from the water prior to letting the water enter the tank. Water softeners are only partially successful in removing all scale-forming properties and are often inoperable due to lack of proper service and maintenance attention

Indirect fired water heaters do not need cathodic protection and are not susceptible to corrosion in potable water. Tank-type water heaters depend on coatings on the tank walls PLUS cathodic protection to prevent corrosion failures. If the anode is not checked and/or replaced at regular intervals, corrosion protection is lost.

Indirect fired water heaters have high recovery efficiency and the efficiency remains high. Tank-type water heaters may have high efficiency when new, but efficiency decreases drastically as the inside surfaces become insulated as layers of scale accumulates.
