Reasons to have Campbell Heating & Air Descale your Water Heater:
Noisy water heater operation: Water heater noises may be the first thing people notice when the water tank scale layer has become thick enough to interfere with good water heater operation.
Longer water heater “on” time & slower water heat-up rate: You can reduce the cost of making hot water with your oil, gas, or electric-fired water heater by removing scale from the tank bottom. The scale layer on the tank bottom (or on an electric water heater’s electrodes) interferes with heat transfer into the hot water.
This means that the water heater will have to operate longer (and you will spend more on hot water costs) than necessary to re-heat incoming water. Clean your water heater tank to reduce your water heating cost by improving heat transfer into the water and correspondingly shortening the water heater “on” cycle time.
High water heater costs to operate, repair, replace: For the same reasons as above: running the water heater longer just to get the water hot enough means higher water heater operating expenses. In addition to higher energy costs to heat the water, unnecessary heater replacement, and in the case of electric water heaters, early failure of the heating elements are common results of heavy scale problems.
Hot water quantity has diminished – not enough hot water: By slowing heat transfer into the hot water in the water tank, the apparent hot water quantity will also be reduced, because incoming cold water is not heated as rapidly when occupants are drawing hot water out of the tank. Thus the incoming cold more quickly dilutes and cools the hot water that remains in the tank during use. Clean the water heater tank to increase hot water quantity.
User dissatisfaction – with the water heater because of less hot water, slower hot water recovery, and higher hot water costs lead to unhappy building occupants who may have no idea that a water heater scale problem is the cause. If dissatisfaction leads a consumer to replace a water heater that could have just been descaled, there may also be unnecessary heater replacement expense.
Extend the water heater life: Because scale on the water heater tank bottom insulates the tank bottom from the water inside the tank, the bottom of an oil or gas fired water heater will become hotter as the scale layer gets thicker. These increased temperatures weaken the water heater tank bottom and shorten the life of the water heater. Similarly, scale deposits on the electrodes in an electric hot water heater shorten the life of the electrodes. Clean the hot water tank regularly to extend its life.
Protect water heater warranty: If a water heater tank fails, the manufacturer may not honor the water heater’s warranty if the failure is due to the accumulation of excessive scale inside of the water heater tank. Water heater warranties typically indicate that the tank is warranted against leaks due to rust, corrosion, or chemical action of the water but the warranty will exclude a tank failure due to scale.
