Hot Water Heater Not Working?

You need hot water to shower, especially if it is cold outside. However, you feel that the water heater takes too long to heat the water. At best, you have lukewarm water to shower with because you simply cannot be late to work. 

If you are looking for a solution, The Belfast Plumber can help you out. Here are some reasons why your water heater is taking longer to heat:


The greater the distance between your water heater and the faucet or shower, the longer it will take for the water to get heated.

Low Volume Restrictor

If you have this installed on your tap or shower, it can delay the hot water.

Failing Water Heater

Sometimes, water heaters can get very old as they approach the end of their service lives. This means they can fail suddenly and you won’t get any hot water. A professional from The Belfast Plumber can come to check what is going on and even replace your water heater.

Sometimes, sediments accumulate inside the water heater and settle at the bottom of the tank. This usually happens where electric heating is located. If a layer of sediment is there, it can prevent the heater from producing hot water. An expert plumber from The Belfast Plumber can come out and sort this problem for you.

Small Water Heater

It could be that your water heater is of a very small size. Perhaps when you got the place, you were living alone. Now, you have a partner. In such a case, the water heater cannot keep up with the demand for heated water. The solution is to get a larger water heater.  Again, The Belfast Plumber can help you with this.

What you can do to get hot water faster?

There are a couple of steps that you can take to fix your water heater and make sure that you get the hot water you need. These are:

Getting A Hot Water Recirculation System

This system has the power to cut down the amount of water wasted while you wait for the hot water to come through the faucet. With the help of this system, the water will rush from the water heater to the tap. Second, the used water is redirected to the water heater, which keeps the water hot. The system is also activated by a timer or thermostat, which helps immensely. This recirculation system can be placed near the tap or the water heater.

Water Heater Without A Tank

This is another option if you want hot water continuously. Tankless water heaters, as the name suggests, don’t use tanks to contain or heat water. Instead, the water touches a heating element and becomes hot. The result is that you can get hot water almost immediately. It is also a good option because it saves you on gas bills. You can also opt for point-of-use tankless water heater units. These are much smaller and are used for individual taps. This is a perfect option for when you have a water heater at home that does not meet the demand. It is easy to install and is usually installed near the faucet.

Adjusting The Temperature

You can always adjust the water heater temperature, and this will give you heated water quickly. You will not have to wait for as long. However, before you change the temperature, you should know that the water heating bill will definitely go up. You will also risk burning yourself if you are not careful.

Insulate The Tank

Once you do that, there is a lesser chance of the heat escaping the water heater. Additionally, the heat will be recovered and this can also lead to a decrease in the gas bills. So you might want to go for this option if you are planning to save on the cost.

Just remember that it can get expensive. For instance, a water heater accounts for about 25 % of the energy’s home use. Consequently, it would help if you chose the water heater that meets your needs and does not put too much burden on your house.

How Long It Will Take You To Get The Hot Water Back?

It depends on the water heater and several other factors. Just remember that all storage water heaters do recover the hot water after a particular time. Some of the factors that aid in this are listed below:

Tank Size

If you have a larger tank, it will take a lot more time for the water heater to recover the heat and to provide you with the hot water immediately. So you might want to plan accordingly.

First Hour Rating

It will take less time for the water heater to recover if the FHR is higher and vice versa.

Fuel Type

It depends on the model that you have. Typically, gas models take a shorter time to heat the water as compared to electric heat waters which take twice as much time.

Temperature Rise

If the water that is circulating the pipes is cold, it will take a longer time to heat. However, if there is warm water circulating the pipe, it will barely take any time.

Look at it this way: if you have an average of 80 gallons gas water heater, it will take an hour for the water to become heated. Only after that will you be able to use it.

Last Words

A water heater is essential, and you have to make sure you choose the right one. If for some reason, it is not working properly and is not giving you the heated water within the time frame you expect, you should fix the problem by reaching out to us at Belfast Company.
