Hot Water Tank Replacement Costs (Expert Guide 2023)

When your hot water system is on the fritz, it’s most likely time for a Sutherland Shire area plumber to perform needed repairs.

And since most units of hot water systems have a life expectancy of anywhere from eight to 14 years, if it’s acting up and older than that, it may be time for a new hot water system, so you’ll need to know the hot water system replacement and hot water system installation cost.

We’ve compiled a list for you of the types of units available, some information about them, and the hot water heater costs of each appliance. Keep in mind, these are estimates and don’t include the labor and other parts necessary for hot water installation.

4 Types of Hot Water Heaters

1. Conventional tank

This type of hot waters system typically consists of a cylindrical tank that is insulated to retain heat. The tank is usually made of steel, with a glass-lined interior to prevent corrosion. Water is heated and stored inside the tank, and a thermostat controls the temperature to maintain a consistent level of hot water.

Smaller conventional tank models, with a capacity of around 25 liters, typically have one heating element, while larger models, with a capacity of up to 400 liters, have two heating elements for faster heating operation. These heating elements are typically made of copper or stainless steel and are designed to heat the water quickly and efficiently.

One of the main advantages of a conventional tank water heater is that it can supply hot water to multiple taps and appliances simultaneously, making it a good choice for larger households. However, the stored water can cool down over time, which means that the heater may need to cycle on and off frequently to maintain the desired temperature.

Overall, a conventional tank water heater is a reliable and cost-effective option for many homes, particularly those with higher hot water demand.

tankless water heater2. Tankless

Uses heated coils to heat the water as it runs through the unit continuously. These on-demand models are becoming more popular because their energy savers as well as have no limit to how much water can be heated so that you won’t run out of hot water anymore.

The hot water system prices of the above-mentioned gas water heater costs range from $450-$1,800. The prices vary depending on the size and style of the unit in question. The lifespan of each also varies.

Now that we’ve looked at electric water heater costs and gas water heater costs, let’s look at hybrid (or heat pump) and solar water heater:

3. Hybrid

A hybrid takes the heat from the air and uses a pump and heating element to heat the water. This type of electric hot water system installation costs more and needs to be placed in an area where it doesn’t get too cold and needs enough air around it to work properly, generally outdoors. Heat pump water heater work by extracting heat from the surrounding air and using it to heat up the water. They are more energy-efficient than traditional electric or gas heater, which means lower electricity bills over time.

However, hot water installations can be more expensive, with prices ranging from $3,300 to $4,000. Another important thing to consider is that heat pump systems can be noisier than other types of hot water systems, so it’s important to take that into account when deciding where to install them. Nonetheless, if you’re looking for a more energy-efficient and environmentally friendly option than traditional electric or gas hot water systems, a heat pump system may be a good choice for you.

solar water heater4. Solar

These solar hot water systems are also becoming more popular particularly if you live in an area like Sutherland Shire where you get a lot of sun. These solar hot water systems are more expensive, as it can range from $3,600-$6,500, depending on whether they are rooftop models or split system models.

These are great if you are considering factors like energy efficiency, as these use the sun’s energy to heat up the water, which means they are not reliant on electricity or gas. This can result in significant operating cost savings on your energy bills over time.

Another benefit of solar hot water system is that they are environmentally friendly, producing zero greenhouse gas emissions. However, it’s important to note that the initial cost of installation can be higher than other types of hot water systems.

Additionally, if you don’t get enough sunlight in your area, a solar hot water system may not be the best option for you.

Also, some models have a gas-powered backup system for when the solar system isn’t getting enough sun and needs a boost. They’re extremely efficient and profitable.

5. Heat pump water heater

Heat pump water heaters are becoming increasingly popular due to their high energy efficiency. This electric hot water system work by extracting heat from the surrounding air or ground and using it to heat water. They can be up to three times more efficient than conventional electric water heater and can save you a lot of money on your energy bills.

However, they can be more expensive to purchase and install than other types of water heaters.

6. Condensing water heater

Condensing water heaters are highly efficient gas-powered water heaters that use a secondary heat exchanger to extract more heat from the combustion gases. These types of electric hot water systems can be up to 98% efficient and can provide significant energy savings.

However, they can be more expensive to purchase and install than other types of gas water heaters.

7. Point-of-use water heater

Point-of-use water heaters are small, compact water heaters that are installed close to the point of use, such as a sink or shower. They are ideal for small spaces and can save energy by eliminating the need for hot water to travel long distances.

However, this hot water system is only suitable for supplying hot water to one or two fixtures and may not be suitable for larger households.

8. Indirect water heaters

Indirect water heaters use a separate boiler to heat water indirectly. This type of hot water system can be highly energy-efficient and can provide a large amount of hot water, but require a separate boiler and are more complex to install. This hot water system is also typically more expensive than other types of water heaters.

9. Tankless coil water heaters

Tankless coil water heaters use a heating coil installed inside a boiler to heat water. This type of hot water system is energy-efficient but can be less reliable and may require regular maintenance. They are typically only suitable for households with a high demand for hot water and a boiler already installed.
