A water heater is one of the costliest appliances you will install in your home. Even in the best of the machines, you may encounter some problems or malfunctions at times.

Though sometimes, there are problems which can be easily solved. While some of them may involve dismantling the unit and checking for the problem. If there is a problem with your unit we suggest you call upon a licensed and professional plumber.

Some of the most common problems that are faced by people are listed below.

Temperature Problems

Sometimes the water can suddenly turn scalding and too hot to be bearable. In such cases the problem can be as small as that of the thermostat setting on the unit. Generally the optimum temperature at which the thermostat should be set is 550 C – 600 C (1300 F – 1400 F).

Noise Problems

At a point, you water heater may start to make some peculiar noises. There may be sediments or debris accumulated inside the water tank. These debris start to make noise as they come in contact with the heating element and start to burn away. Usually, flushing the tank out may solve this problem. If, even after flushing, the noise prevails, it may be time to change the heating element.

Deteriorating water quality

The Anode rods present in the heater will prevent the insides from rusting and will help maintain the water quality. These rods are hard and brittle and wear off after a point of time and have to be replaced. If there is black or rusty water coming out, these rods may have to be replaced.

The black water may be a result of the residue from the rods getting mixed in the water and the rust may be a result of the water reacting with the steel in the anode rods’ absence.


There are many complaints regarding leaks in a water heater. Unfortunately, there is no specific reason or a standard solution for this. The best option would be to call upon a professional.

Water Heaters in winter

In winters, there may be a deficiency of hot water due to sub-zero temperatures, outside. It may be a result of insufficient pipe insulation. Using a heat tape or a pipe insulation will be a good option. Check for particularly drafty spots around the water heater. If there are any, adding extra insulation to the walls can help.

Care should be taken while handling a water heater that the gas line and the electricity are switched off. Even the water line valve must be turned off to avoid the flowing water being spewed everywhere. If you are unsure, or you’re not confident about your skill or ability to solve the problem, immediately call a water heater specialist in your area.
