WATER PIPING AND CONTROLS

Antifreeze solutions expand more than water. For example, a 50% by volume solution expands 4.8% for a 148°F temperature rise while water expands about 3% for the same temperature increase. Allowance for this expansion must be considered in sizing expansion tanks and related components.

4.The flow rate in systems utilizing glycol solution should be increased compared with a water system to compensate for increased heating capacity.

5.Due to increased flow rate and fluid viscosity the circulator head requirement will increase. Contact the pump manufacturer to correctly size the circulator for a particular application based on the glycol concentration and heating requirements.

6.A strainer, sediment trap, or some other means for cleaning the piping system must be provided. It should be located in the return line upstream of the boiler and must be cleaned frequently during the initial operation of the system. Glycol solution is likely to remove mill scale from new pipe in new installations.

7.Glycol solution is expensive and leaks should be avoided. Weld or solder joints should be used where possible and threaded joints should be avoided. Make up water should not be added to the system automatically when a glycol solution is used. Adding make-up water may significantly dilute the system.

8.Check local regulations to see if systems containing glycol solutions must include a back-flow preventer or require that the glycol system be isolated from the water supply.

9.Do not use galvanized pipe in glycol systems.

10.Use water that is low in mineral content and make sure there are no petroleum products in the solution.

11.Mix solution at room temperature.

12.Do not use a chromate treatment.

13.Do not use glycol solution in a system that may reach temperatures above 250°F.

14.Refer to Technical Topics, #2a published by the Hydronics Institute Division of GAMA for further glycol system considerations.

F.SPECIAL APPLICATIONS

1.If the boiler is used in conjunction with a chilled medium system, pipe the chiller in a separate secondary loop.

a.Assure that the boiler circulator is disabled during chiller operation so chilled water does not enter the boiler.

b.Install a flow control valve (spring check valve) to prevent gravity flow through the boiler.

c.See figure 3.8 for recommended system piping.

2.For boilers connected to heating coils in a forced air system where they may be exposed to chilled air circulation, install flow control valves or other automatic means to prevent gravity circulation of the boiler water during cooling cycles. See figure 3.9 for illustration.
