BOLD TYPE indicates Low NOx models.
ΔT = Temperature Rise, Degree F@GPM FLOW
GPM = Gallons per Minute Flow
ΔP = Pressure Drop, Foot thru Heat Exchanger
MPS = Minimum Pipe Size, NPT
SHL = System Head Loss
* Must utilize optional cupro-nickel tubes. If over 25 grains per gallon, a water softener/treatment system must be utilized.
Table I: General Specifications Uni-Temp 80 Hot Water Supply Systems
Piping—Domestic Hot Water
Supply Heaters
Table I above provides data for selecting in-line pumps
for use in a Uni-Temp 80 system for a single heater
and tank according to the following:
1. Flow rates are based on water hardness as meas-
ured in grains per gallon.
Soft: 0-4 grains per gallon.
Medium: 5-15 grains per gallon.
Hard: 16-25 grains per gallon.
2. Maximum Flow Rates:
0133 22 GPM
0181-0401 45 GPM
0514-1826 90 GPM
2100-4001 200 GPM
3. Pressure drop values (ΔP and SHL) and minimum
pipe sizes are for two-pass heaters.
4. Sizing based on heater and tank being placed 5
feet apart. The equivalent length of pipe, valves
and fittings in the system is as follows:

1-1/2" NPT = 70 Ft (0181-0401)
2" NPT = 75 Ft (0514-0824)
2-1/2" NPT = 80 Ft (0926-1826)
3" NPT = 85 Ft (2100-4001)
Additional pipe fittings will increase the system
head loss.
5. Select a pump based on the water hardness, flow,
and system head loss.
6. If heater is more than two stories above the tank,
consult the factory.
NOTE: GPM flow rates are limited by maximum
acceptable velocity through heat exchanger tubes.
Heater models 0514 through 1826 may be provided
with an integral rear-mounted pump. This must be
specified at time of order.
MINIMUM INPUT ADJUSTMENT: Model Types WH
have minimum input ratings as specified on their indi-
vidual rating plates. Minimum input controllers have
been pre-set at the factory. Consult with factory repre-
sentatives if a minimum input problem should occur.
