Sample Specifications
TR_______or equal
1. Hot water tank designed for production of domestic hot
water using hot water as heating source. The principle
consists of two concentric tanks. The inner tank con-
tains domestic hot water and the outer tank contains
heating system water. The inner tank shall have a capac-
ity of ________gallons.
2. The inner tank material shall be 304L corrugated stain-
less steel or higher corrosion resistance stainless steel,
and have a working pressure of 150 psi or more. The
cold water connection into this tank shall extend to near
the bottom of the tank. The hot water connection shall
be at the top of the tank. Tank shall be designed to be
self descaling.
3. The outer tank material shall be carbon steel with a built
in air vent. The working pressure shall be 45 psi max-
imum.
4. The tank shall have a minimum of _________ square
feet of heat transfer surface.
5. The outer tank shall have a minimum of 2 inches of
polyurethane foam insulation or insulation with an
equivalent “R” factor value installed on all sides.
6. The tanks shall be installed in a steel cabinet which has
been finished with a baked enamel paint.
7. The inner tank shall be equipped with a dry well. In the
dry well shall be a remote sensing bulb to indicate water
temperature in the tank, and an additional remote sens-
ing bulb for a low voltage thermostat. The thermostat
should be adjustable from low to high temperature.
The thermostat shall open the circuit when the tempera-
ture rises above the set point and shall close when the
temperature has no more than a (6) degree differential
between the opening temperature and the closing tem-
perature.
8. Tank shall be installed with a temperature/pressure
relief valve. Valve shall relieve pressure at 150 psi.
Relief temperature shall be 210 degrees.
