Fluid Testing and Treatment
Proper fluid quality management is essential to protect your investment and longevity of Greenwood boilers.
Before filling the boiler with water, draw a sample of the supply water to be used and send it to a Greenwood
authorized lab for testing (see below). The sample will be analyzed and specific recommendations made for
appropriate water treatment. Thereafter, annual testing of the boiler fluid with a Greenwood authorized lab is
recommended to ensure appropriate fluid quality. In addition, proof of annual water analyses and treatment is
required to maintain the warranty on Greenwood boilers.
Water sample analysis allows for matching water conditions to the appropriate mix of treatments. Target
fluid properties are as follows:
When filling the boiler, the water pH should be greater than 6.5 and have a pH greater than 8.5 once
inhibitor has been added. If the fluid that passes through the boiler contacts any copper component,
the PH should be maintained in a range between 8 to 10.
Chloride should optimally be below 30 ppm. In some parts of the country this is not possible, in
these situations 50 ppm is the absolute maximum.
Water hardness should be below 100 ppm (6-7 grains).
Nitrite is not included in our approved treatments as nitrites promote bacterial growth in vented
systems.
Conductivity should not exceed 3,500 mmhos in treated water. Without high nitrite levels, the
conductivity may be under 1000 mmhos (using Boiler Pro 925.)
Once treated, the pH and treatment level of the water should remain stable as long as the water is not lost and
added to the boiler. If water is added to the system:
1.
A proportionate amount of inhibitor should be added to maintain the appropriate level of protection
against corrosion and scaling.
2.
The system fluid should be re-tested annually.
Your expansion tank should include a sight glass to easily confirm water level. Check the water level each
time you stoke the fire to ensure the correct fluid level. Oxygen buildup causes corrosion inside the water
system. Keeping the water level full avoids oxygen buildup, especially during the summer months when the
furnace is not in use. Properly treated water should also be left in the boiler if it is not being operated for an
extended period of time.
