Open Loop - Ground Water Systems

Shut off valves should be included for ease of servicing. 
Boiler drains or other valves should be “tee’d” into the 
lines to allow acid 

fl

 ushing of the heat exchanger. Shut 

off valves should be positioned to allow 

fl

 ow through 

the coax via the boiler drains without allowing 

fl

 ow into 

the piping system.  P/T plugs should be used so that 
pressure drop and temperature can be measured. Piping 
materials should be limited to copper or PVC SCH80. 

Note: Due to the pressure and temperature extremes, 
PVC SCH40 is not recommended.

Water quantity should be plentiful and of good quality. 
Consult table 3 for water quality guidelines. The unit can 
be ordered with either a copper or cupro-nickel water 
heat exchanger. Consult Table 3 for recommendations. 
Copper is recommended for closed loop systems and 
open loop ground water systems that are not high 
in mineral content or corrosiveness. In conditions 
anticipating heavy scale formation or in brackish water, 
a cupro-nickel heat exchanger is recommended. In 
ground water situations where scaling could be heavy 
or where biological growth such as iron bacteria will 
be present, an open loop system is not recommended. 
Heat exchanger coils may over time lose heat exchange 
capabilities due to build up of mineral deposits. Heat 
exchangers must only be serviced by a quali

fi

 ed 

technician, as acid and special pumping equipment 
is required. Desuperheater coils can likewise become 
scaled and possibly plugged. In areas with extremely 
hard water, the owner should be informed that the 
heat exchanger may require occasional acid 

fl

 ushing.  

In some cases, the desuperheater option should not 
be recommended due to hard water conditions and 
additional maintenance required.

Water Quality Standards

Table 3 should be consulted for water quality 
requirements. Scaling potential should be assessed 
using the pH/Calcium hardness method. If the pH 
<7.5 and the calcium hardness is less than 100 ppm, 
scaling potential is low. If this method yields numbers 
out of range of those listed, the Ryznar Stability and 
Langelier Saturation indecies should be calculated. 
Use the appropriate scaling surface temperature for the 
application, 150°F [66°C] for direct use (well water/open 
loop) and DHW (desuperheater); 90°F [32°F] for indirect 
use. A monitoring plan should be implemented in these 
probable scaling situations. Other water quality issues 
such as iron fouling, corrosion prevention and erosion 
and clogging should be referenced in Table 3.

Expansion Tank and Pump

Use a closed, bladder-type expansion tank to minimize 
mineral formation due to air exposure. The expansion 
tank should be sized to provide at least one minute 
continuous run time of the pump using its drawdown 
capacity rating to prevent pump short cycling. Discharge 
water from the unit is not contaminated in any manner 
and can be disposed of in various ways, depending on 
local building codes (e.g. recharge well, storm sewer, 
drain 

fi

 eld, adjacent stream or pond, etc.). Most local 

codes forbid the use of sanitary sewer for disposal. 
Consult your local building and zoning department to 
assure compliance in your area. 

Water Control Valve

Always maintain water pressure in the heat exchanger 
by placing the water control valve(s) on the discharge 
line to prevent mineral precipitation during the off-cycle. 
Pilot operated slow closing valves are recommended 
to reduce water hammer. If water hammer persists, a 
mini-expansion tank can be mounted on the piping 
to help absorb the excess hammer shock. Insure that 
the total ‘VA’ draw of the valve can be supplied by the 
unit transformer. For instance, a slow closing valve can 
draw up to 35VA. This can overload smaller 40 or 50 
VA transformers depending on the other controls in the 
circuit. A typical pilot operated solenoid valve draws 
approximately 15VA..

Flow Regulation

Flow regulation can be accomplished by two methods. 
One method of 

fl

 ow regulation involves simply adjusting 

the ball valve or water control valve on the discharge 
line.  Measure the pressure drop through the unit heat 
exchanger, and determine 

fl

 ow rate. Since the pressure is 

constantly varying, two pressure gauges may be needed. 
Adjust the valve until the desired 

fl

 ow of 1.5 to 2 gpm per 

ton [2.0 to 2.6 l/m per kW] is achieved. A second method 
of 

fl

 ow control requires a 

fl

 ow control device mounted 

on the outlet of the water control valve. The device is 
typically a brass 

fi

 tting with an ori

fi

 ce of rubber or plastic 

material that is designed to allow a speci

fi

 ed 

fl

 ow rate. 

On occasion, 

fl

 ow control devices may produce velocity 

noise that can be reduced by applying some back 
pressure from the ball valve located on the discharge line. 
Slightly closing the valve will spread the pressure drop 
over both devices, lessening the velocity noise.  

NOTE:  

When EWT is below 50°F [10°C], 2 gpm per ton (2.6 
l/m per kW) is required.
