Test Parameters and What They Mean
Conductivity
Conductivity is a measurement of minerals in your furnace
water. While it is common to have minerals in water, in
excess minerals can cause many problems in hydronic
systems including scaling and corrosion.
pH
pH is a measurement of alkalinity (hard or soft water). For
outdoor furnace water and the water treatment used in
outdoor furnaces, it is better to have your water a little
harder than softer (recommended pH range is 8.5-10) as
the active ingredients in the water treatment neutralize
harder water easier than softer water.
Nitrates
Nitrates tested for are a measurement of how much
water treatment is in the water. Nitrates measured are

harmful elements in your furnace water. Nitrates also act
to neutralize harmful bacteria that may build-up in the

furnace water over time.
Glycol
Inhibited glycol provides anti-corrosion elements and
freeze protection for outdoor furnaces and is compatible
with Outdoor Furnace Water Treatment. Because outdoor
furnaces are open to the atmosphere systems and will
have fresh water added occasionally, oxygen is always
entering the system and will break down the glycol over
time to create glycolic acid which will harm your furnace
