Helping you get the most out of your
hot water system
To keep water heaters running at peak efficiency, it’s important to
remove scale from inside the tank. Regular scale removal saves money and
prolongs the life of the entire water heating system.
Scale is a hard, whitish coating that can build up on any surface that
comes into regular contact with hard water. Hard water contains more
minerals than soft water, and mineral levels vary from city to city.
Generally speaking, groundwater contains more minerals because minerals
from the soil are in the water. River or lake water usually contains
fewer minerals and, therefore, is softer.
A problem that needs to be addressed
Scale buildup can reduce the useful life of a water heater and greatly increase operating expenses. Scale that accumulates
inside a water heater covers the inside walls and heat exchanger
surfaces, increasing operating time as these surfaces lose direct
contact with the water.
As little as 1/16" of calcium scale on the heating transfer surfaces can
reduce heating efficiency drastically. That means the heater has to run
more often and longer, shortening its life, increasing repair costs and
driving up operating costs.
Often the heater will make loud knocking or rumbling noises because of
water boiling between the scale and the tank wall.
The hot water may smell musty or look murky, and will discolour surfaces
that it contacts. Occasionally there will be white flakes in the hot
Reduced energy efficiency
Maintaining higher operating temperatures and heating water through a
layer of scale increases the water heater’s energy consumption.
Scale build-up can reduce a gas water heater’s efficiency and also reduce its life. All else remaining equal, energy consumption
increases as the scale thickens.
