Basics of the Water Heaters 

You should be aware that the water heaters are machines that convert energy to heat thus creating and supplying hot water throughout your place. How does a hot water heater work? Before we answer the question, there are some different types of systems concerning water heaters. Most of the residential units can although be divided into two categories: 

Tank-type Water Heaters 

This is the most common and used water heater by most people. It is simply a tank that is used to hold and store hot water. This type of water heater is mostly found in older homes as opposed to new modern age homes. 

This type of water heater is losing its popularity slowly simply because it is very inefficient today. The tank-type water heaters hold the heated water till the time of need at your place. 

How Tank-type Water Heaters Work 

The water heaters that have tanks can either run on electricity or rather fuel and have about three pipes for transferring water. The work of the pipes is to respectively bring in cold water, move out hot water and one acts as the safety valve of which in case the temperature or rather the pressure exceeds the safety limit, water is released from the water heater tank. 

The pipe that brings cold water in, ensures water is brought so as to undergo heating, where the elements of heat are found at the tank’s bottom. When the water is undergoing heating, it rises towards the tank’s top in order to be released by the pipe that releases hot water. 

In case you are not using hot water, the water remains in the heater’s tank continuously undergoing heating. In case hot water has all been used, you can experience a delay that may force you to be patient as the tank refills. As of now, you can be able to know how the tank-type water heaters work. 

Tankless Water Heaters 

Tankless water heaters nowadays are widely known by many people simply because of the increased efficiency of energy. These types of water heaters heat the water when demanded to, instead of continuously running in order to keep the water hot. 

However, it has some disadvantages that include low flow rates, particularly if your water heater unit doesn’t have at least a small unit for storing water. The water storage units are supposed to increase the flow rates while the hot water present is being used instead of holding it. 

How The Tankless Type of Water Heaters Work 

The tankless type of water heater works by the use of a coil that heats the cold water. Most people wonder how a water heater works, well we got you covered. There are two kinds of tankless types of water heaters that include standalone and boiler-mounted. 

The boiler-mounted water heaters depend on the boiler to produce heat as opposed to the standalone water heaters that use a gas fire together with a heat exchanger and a coil.  

Basic Troubleshooting 

Temperature issues 

How does a hot water heater work? You already know now and you should also be aware of the troubleshooting mechanisms. In case the hot water is not present, first check the breaker. In case there is a fuse that has blown it could be one of the problems as to why the heater is not working. 

Be sure that you have identified the problem. In case your thermostat and the electrical breakers are okay, the possible problem could be the heating element which has malfunctioned and has to be instantly replaced. 

In case the hot water is not enough, the most likely problem could be with the thermostat. In case you are at least receiving some warm water, the water would be least warm and quickly running out. 

In case the thermostat has malfunctioned, you should be aware of the type of water heater present in order to locate it very easily. On some of the electrical models, you can find it behind the access panel, which is not used after the initial setup.

 In case the water is very hot, the most likely problem could be again at the thermostat. You should be able to check this before already changing the setup temperature as the primary solution. In case this solution doesn’t help, the most likely problem is an issue concerning wiring that a professional should handle. 

Takes a long time to heat 

In case your water heater takes a long duration to heat, the most likely problem could be at the heating unit or rather the thermostat. You can also read the user’s manual to check the duration at which the water heater present takes to refill its supply. 

Low water pressure 

Most of the older homes tend to have bad water pressure because of their original plumbing. The most likely solution to this problem could be replacing some pipes so as to ensure the water pressure is increased. Another problem could be the presence of a leak in the pipes. 

Smelly water, rust, and dust 

In case your water is rusty, the most likely solution is for you to replace the anode rod or you should replace the tank in case the tank is corroded. In case your water smells bad, the most likely problem could be bacteria growth. The most likely solution is for you to flush the tank and also replace the anode rod.
