In Singapore, water heaters have become popular due to their convenience in providing hot water, which is almost necessary during cold weather. It is important to note that there are two kinds of water heaters that a plumber can install an instant water heater and a storage water heater.

Below are some things that you should know during a water heater installation.


Ensure to Identify and Locate Place of Installation


Storage water heaters are usually installed above the false ceiling because of their bulky size. However, if you do not have the suitable space for your storage water heater, install an instant water heater instead.

For instant water heaters, a plumber can set this up against a plaster along with a drywall. They can also be installed by undergoing a drill installation which requires a stud. This is messy and not easy unless you are knowledgeable about it. If not, it is best to call a plumber to help you choose between a storage water heater or an instant water heater as well as install it afterward.


Check The Water Supply Route


The water that will pass through the showerhead, as well as the tap, will depend on what type of water heater you use. If you are using a storage water heater, the water in the pipes will be stored in the tank. Then, you can use them afterward. For an instant water heater, you can use the water instantly because it just takes a split second to heat the water. However, there can be signs that your water heater is faulty, when this happens you can experience water heater issues. These are the things that you should take note of during a water heater installation.


Make Sure The Heater Is Mounted Properly

When mounting a water heater like Joven or Everhot, one thing you need to check is the space between the water heater unit and the wall. A distance as small as 1.5 inches can be dangerous. There is still a need to put brackets, which is why a decent amount of space between the tank and the wall should be allotted. 


Inspect The Water Pipes


Copper and stainless steel pipes are durable – which is why they are the most popular choices of water pipes for storage water heater installations. Stainless steel pipes easily complement the bathroom, so it is preferred by some homeowners. On the other hand, copper pipes are better for other people because the corners have less bends. Given these varying preferences, check with your water heater service provider before the installation.


Check The Relief Valve Connection

You may avoid these causes of water heater failure if you make sure to pay attention to this component during installation. Relief valve connection is the one responsible for releasing water droplets into the air. The water droplets are directed into a drainage point by a tube that is attached to the relief valve. The rubber tubing connecting the valve to the drainage point is frequently missing and not attached. Hence, you have to ensure that your installer does not dispose of it during the instant water heater installation


Check The Mini Stopcock Valve


Stopcock valve functions as a tap that controls the flow of water. This can be found at the water pipe connecting to the inlet. This component is helpful if your water heater leaks or if you need to turn off the incoming water supply to the unit in case of water heater issues and maintenance.


Test Before Using


After the installation, you should not start up electricity lines but only the water valves to ensure your water heater safety. Remember to open the faucets and get the water running to the water heater for about 1-2 minutes. Shut the valves off. Get the inline filter off found close to the inlet, and remove any debris you find. Lastly, test the appliance to ensure that it is functioning correctly as well as make sure that no water heater leakage occurs.
