An instant water heater is a convenient gadget for home use. Water heaters are usually fueled by gas or electricity, which are both convenient and efficient. However, the water heater is not without its problems. Fortunately, when something is amiss you will quickly notice. Below are 5 common problems associated with an instant water heating system.
Inadequate Hot Water
It is important that you get a heater that is commensurate to household water heating demands. If the heater is undersized, it is unlikely to supply adequate hot water. A faulty part in the heater may interfere with sufficient water heating. Faulty gadgets may include an electric thermostat, heating element, gas pilot and pilot control valve. Sometimes water may not heat beyond lukewarm temperature.
Hot water may also be supplied just briefly before it turns cold. This is often caused by a faulty heating element. Certain parts tend to get loose with continued use. Sometimes all that is needed is to tighten a particular part. Should you identify a damaged part, you’d have to replace it. Inadequate hot water may also be caused by improper plumbing. Faulty installations frequently cross hot and cold water links.
Excessively Hot Water
The sound of boiling water in the heater indicates water that is too hot. You may also have emissions of steam or hot water from the faucets. Temperature and pressure settings need to be checked. Adjustments can be made where appropriate. The pressure valve may have been improperly placed. Or it may be damaged which calls for replacement.
You may hear some rumbling or popping sound when the heater is in use. This usually indicates boiling water at the bottom of the water tank. It is caused by an accumulation of sediment in the tank. To resolve this problem you need to remove the sediment. This can be done by flushing the water heater. Electric water heaters may occasionally give a high pitched whining sound. This is caused when scale substance accumulates on the heating element. You need to clean the tank and elements to eliminate the scale.
You may identify dripping or puddles at the base of the water heater. Possible causes are overheating, corrosion, faulty plumbing or excessive pressure. To correct overheating you need to reduce the thermostat setting. Corrosion usually calls for replacement of the heater. Check plumbing connections to ensure that all is in order. Faulty connections must be corrected. Excessive pressure may cause the temperature and pressure valve to leak. A leaking valve needs to be replaced. Be sure to maintain pressure settings within an ideal range.
Corrosion in the water tank is the most frequent cause of water discoloration. A faulty anode rode may also cause water to discolor. Anode rods are usually placed in the water tank to prevent rust. They dissolve slowly and counteract rust formation. A faulty anode rode needs to be replaced.
