Step 1: Pre-Installation Preparation

There are a few essential tasks that must be completed before the actual installation. This includes determining the position of the water heater, ensuring all the necessary tools are handy, and if there is an old system, it should be discarded. This process can take 1-2 hours, depending on the complexity of the whole process.

Step 2: Removing the Old Water Heater

If you are replacing the old water heater, then removing it is the next process. This involves first shutting off the water supply, then draining the old tank, and, at last, disconnecting the connections. For the water heaters, wiring the unit correctly is essential. This process can take around 1-2 hours, depending on any unexpected complications that may arise.

Step 3: Installing the New Water Heater

The actual installation process of the water heater starts with removing the old water heater and connecting the new unit to the existing plumbing and utility connections. This includes attaching the water lines and ensuring proper ventilation. So, how long does it take to install a water heater? This step can take around 2-4 hours, depending on the type of water heater and the complexity of the process.

Step 4: Testing and Inspections

After the installation is done, thorough testing is required. It is essential to make sure that everything is working properly. There are no leaks. The temperature is proper. All the settings are correct. This process can take around 1-2 hours.

Step 5: Cleanup and Final Touches

Once everything is done and properly installed, then the final thing to do is clean up the whole work area and make any final adjustments if required. This process includes discarding the old water heater and checking the installation area is left in good condition. This process usually takes 1 hour.

When Do You Need a New Water Heater?

When Do You Need a New Water Heater?

If you suddenly get cold water during a shower or you have to use chilly cold water for washing dishes, but you are not getting warm water. This means that your water heater is not working anymore. Also, there may be some cases in which water leaks around the water heater. Then, it is a signal to replace your water heater.

Some signs show that your water heater is showing signs and having problems. It’s a good idea to pay attention to these signs. Before the water heater completely stops working, it can be costly.

Here are some of the key indicators that you need a new water heater:

  • Age of the water heater: A water heater typically lasts from 8 Years to 10 Years. Even if it runs perfectly, you must consider replacing it as your unit runs or exceeds this age range.
  • Rust and corrosion: Rust and Corrosion are signs of wear and tear on the water heater’s tank and connections. Rust weakens the metal and can eventually lead to leaks. Corrosion can affect the efficiency of the water heater as it inhibits heat transfer. Check for any reddish-brown stains, flaking metal, or signs of deterioration around the tank and fittings.
  • Leaking: Any presence of water near the water heater, whether it is a small puddle or pooling beneath the unit, suggests a leakage. While some leaks can be repaired, significant or persistent leaks might need to be replaced because repairs might not be long-term solutions.
  • Inadequate warm water: If your water heater is unable to supply adequate hot water for your needs, then it indicates there may be a problem with the water heater. Sometimes, sediment builds up in the bottom of the tank of the water heater. This insulates the water heating. This results in the reduction of the efficiency of the water heater. While these issues can, at times, be fixed, if they continue regularly, a new water heater may be a preferable option.
  • Strange noises: Sediment buildup in the bottom of the tank of the water heater is frequently the origin of strange noises from the machine. Strange sounds include gurgling, popping, or rumbling. Removing the sediments from the water tank might be helpful in some cases, but if the sound continues, then it could be a sign that the water heater needs to be replaced.
  • Rusty water: If the water appears to be rusty or discolored, it suggests the water inside the tank is deteriorating. This could be due to rusting mastering inside the heater. You can get rid of this discolored water after running the tap for a few minutes. But if the disclosed water persists, then it is a clear indication that the heater’s internal components are deteriorating.
  • Increased electricity bill: Old water heaters can become less energy efficient because of the sediment buildup, reduced heating performance, and increased heat loss from the tank. If you notice a significant rise in the electricity bill without any other explanation, you should check whether your water heater is contributing to the increased energy consumption or not.
  • Physical damage: Dents, cracks, or other physical damage to the water heater tank can affect the structural integrity of the tank. Physical damage decreases the efficiency of the water heater and increases the risk of leaks. Even though the damage seems small, you must address the problem immediately.

Types of Water Heaters and How Long Does it Take to Install

Types of Water Heaters and How Long Does it Take to Install

  • Tank Water Heater: Tank water heaters are the most common type of water heater. They are available in various sizes. They store and heat water in a tank. The installation of a Tank Water Heater takes around 2 to 4 hours approximately.
  • Tankless Water Heater: Tankless water heaters are currently the most demanding water heaters. This type of water heater heats water directly as it flows through the unit. They are more energy efficient. However, these water heaters are more complex to install because they need proper venting and gas/electric connection. The installation might take 4 to 8 Hours approximately.
  • Point-of-Use Water Heater: Instead of providing warm water to the whole house, the point-of-use water heater only supplies hot water to a specific part of the plumbing fixture, like a kitchen sink and many more. They have a small tank to store a limited amount of water for immediate use. The installation of these types of heaters is relatively quick and takes approximately 1-2 hours.

Point-of-Use Water Heater

  • Solar Water Heater: Solar water heaters use energy from the sun. This reduces yearly utility costs as they consist of solar collectors and storage tanks. They have a large insulated tank where the water is stored. It is stored until it is ready to be used. The solar water heaters are mounted on the roof with solar panels. Installation time can vary significantly depending on the type of solar system you choose. And how long does it take to install a water heater? It can take up to 8 to 16 Hours or more.
  • Hybrid Water Heater: A hybrid water heater works differently than the traditional one. It utilizes a heat pump to extract heat from the ground and the air instead of burning direct fuel to warm the water. A hybrid water heater can use about 60% less electricity than a standard tank water heater because of this unique heating method. The installation time can range from 4 to 6 hours.


  • Combination Boiler Water Heater: A combination boiler water heater is a single unit that does two things- it warms up the house and heats the water in different plumbing fixtures of the house. This water heater doesn’t cost much to run, which is good for smaller homes. The installation might take around 3 to 5 hours.
  • Condensing Water Heater: Condensing water heaters are typically used with natural gas. They use heat from the exhaust gas that may be otherwise wasted. Condensing water heaters keep your electricity bill lower and use energy efficiently. And how long does it take to install a water heater? The time of installation of these water heaters may take up to 4 to 6 hours.
