To conserve energy, the water heater will not utilize a continuously operating, integral circulation pump between the
storage and heating section.
The water heater will be a vertical fire tube design that is constructed and stamped in accordance with Section IV,
Part HLW of the ASME code. Both the storage and heating sections of the water heater will be National Board
Registered for a working pressure of 150 psi and will be pressure tested at 1-1/2 times working pressure. For maximum
thermal strength, the fireside of the heating surfaces will be of boiler-grade steel. For corrosion protection, the waterside
of the heating tubes will be sealed in copper. The heating tubes will be rolled, beaded, and seal welded into the tube
sheets. The combustion side of the tube sheet will be insulated by a layer of ceramic fiber that will protect the tube sheet
from both thermal stresses and failure that can result from the accumulation of scale and precipitants.
