What is the cheapest way to replace a water heater?

When compared to traditional tank heaters, this tank is a good way to save money while still getting a high-quality water heater. A standard tank-style also offers you a longer warranty than most other models, which is a testament to its durability. This heater will last for about 15 years with proper maintenance. If you’re looking for the cheapest way to replace your water heater, this is the model you should go for. [1]

How much does it cost to replace a 50-gallon hot water heater?

Hot water heaters with a capacity of 50 gallons are intended for homes with a modest need for hot water, ranging from 3 to 5 occupants. Electricity, gas, or propane are all viable fuels for these tank-style heaters. Hot water heaters fueled by gas or propane are offered in a variety of efficiencies, which can lower their operating costs but raise their original cost. The total expenses you incur depend on performance, fuel type, and replacement site.
The cost of replacing a 50-gallon hot water heater ranges from $1,100 to $2,800 on a national level, with the majority of consumers spending approximately $1,800 to replace a 50-gallon gas hot water heater with the exact same type. It will only cost $770 to replace a 50-gallon electric hot water heater in a visible and accessible location. A high-efficiency 50-gallon gas hot water heater replacement project with upgrades will cost $4,200. It will be installed on a brand-new, challenging-to-access site.

How much does it cost to replace a 40-gallon gas water heater?

Standard 40-gallon water heaters range in price from $330 to $1,500 for the equipment alone, or from $500 to $2,500 when you add up the cost of installation. A 40-gallon water heater may easily accommodate the demands of a two-person household and can prove to be sufficient if you are looking for a cost-effective option.

Considerations for Replacing a Water Heater


There are a lot of varieties of water heaters, each manufactured by a different manufacturer. For example, Rheem, Bosch, Reliant, and Bradford White are a few of these, and each of them comes in a different price range. This is one factor that you should be aware of. The energy source will also affect your price range. The prices for gas and electric water heaters vary significantly.


You should also be aware that every heater has a different lifespan. A tank-style hot water heater lasts 10 to 15 years on average, while a tankless one might last longer.


In order to clear out any sediment on the bottom, hot water heater maintenance often involves draining the tank on a regular basis. While this can also be a DIY project, extensive maintenance might require a professional to drop in, so you will need to factor in the cost of possible maintenance.


The size of some hot water heaters necessitates floor mounting. This would mean that you would require some floor space for the installation. You can be sure that the cost of labour for a water heater that requires mounting will differ slightly from one that doesn’t.


You may incur extra charges of between $8 and $10 per linear foot if you require more plumbing to transport the hot water from your heater to your home.


In most places, installing hot water heaters doesn’t require a permit. Always check with your plumber or your local government for further information since this might vary from town to town.

Tank Removal and Relocation

On occasion, an installation will tack on extra fees to get rid of an old water tank in order for the new one to be placed. Also, if you wish to have a water heater moved or converted from one fuel type to another, the cost may vary substantially. A water heater relocation project might cost as little as $200 or as much as $10,000. Your water heater may cost extra to convert between different fuel sources. Changing from electric to gas, for instance, necessitates new gas lines, which can increase installation costs by $1,500 to $2,300.

Carpentry Work

Carpentry work can be necessary for your water installation, such as removing or installing woodwork in your attic to provide room for a heater. As a result, labour costs and labour hours increase.


For water heater installation, venting pipes, pressure valves, water and gas pipework, thread compound, solder, and other supplies are all needed. For installations that are more difficult, there might be a need for additional materials. This will affect the cost of installing your water heater. There is also the expansion tank. This tank is made to accommodate water’s thermal expansion while reducing excessive water pressure. Tanks for expansion range in price from $40 to $150.

What is the average labor cost to replace an electric hot water heater?

The cost of labor might range from $150 to $1,000 or more, however, depending on the type and size of the water heater. The cost of replacing a 50-gallon hot water heater will vary depending on the type of heater you choose. If you select a tankless model, you can expect to spend around $1,500 on the unit and installation. For a standard tank-style heater, you can expect to pay between $600 and $1,000 for the unit itself, and an additional $500 for the installation labor.

The cost of replacing a 40-gallon gas water heater will be lower than the cost of replacing a 50-gallon hot water heater. Tankless models are available for around $1,000, while standard tank-style heaters can be found for as little as $320 Installation costs will be similar to those for a 50-gallon hot water heater.

If you have a tight budget, it may be possible to find a used water heater for sale. However, it is important to remember that a used water heater may not have the same lifespan as a new unit, and it may not be covered by a warranty. When shopping for a new water heater, be sure to compare the cost of the unit itself as well as the cost of installation labor. In some cases, it may be cheaper to purchase a tankless unit and have it installed by a professional. However, if you have the time and ability to install the unit yourself, you may be able to save money by doing it yourself.

If you are unsure about which type of water heater is right for your home, or if you have questions about the installation process, it is always a good idea to contact a professional plumber. We are always open to hearing your questions and attending to every one of your needs. Even better still,  will be able to help you select the perfect unit for your home and walk you through the installation process step-by-step.

How long does it take to install a water heater?

The time it takes to install a water heater varies depending on the type of unit you have, the size of your home, and whether or not you are doing it yourself. In most cases, however, it should not take more than a few hours to complete the installation process. If you are having trouble installing the unit yourself, it is always a good idea to contact a professional plumber. They will be able to complete the job a lot quicker and make sure that everything is installed correctly. Our plumbers are skilled and will work hard to do the job in two to three hours if there are no problems or obstacles.

 You must make a few choices to begin your water heater replacement process, whether you are doing it willingly or compelled to do it after extensive repairs and annoying leakages. These are the steps that come with purchasing and installing a new water heater with us that you should be aware of:


Our service specialists will first pay you and visit you to assess your current water heater condition and assist you in choosing the best water heater for your requirements and financial position. This might involve swapping out your outdated water heater for one with a similar conventional tank or choosing one of our tankless options. We also provide funding choices.

Set a time for the appointment.

As we previously stated, an appointment must be scheduled as soon as possible if it is an emergency. Even if it isn’t, it must be made right away to avoid any potentially expensive breakdown. So, you pick a date that is most convenient for you once we work out the instalment agreement.

Clearing the area around the heater

To provide the repair specialists easy access to the heater, it is important that the entire area is clear of any boxes or other objects that may be nearby.

Taking Out The Old Heater

A new water heater must be removed using a few steps, just like when it is installed. It is necessary to empty the tank, cut off the electricity and gasoline, and then remove it. Because of the complexity of this process, it is handled completely by our trained professionals.


The amount of time required depends on where it is placed and how easy it is to enter. The new heater must also be brought inside your house and moved into the proper location. An electrical or gas source must be linked to the tank. Due to extra venting and safety concerns, if it is a gas heater, this will probably take a little longer. The plumber will check it out and make any necessary adjustments when the installation is finished and the tank is full.

How much does it cost to replace a tank water heater with a tankless one?

The cost of replacing a tank water heater with a tankless model will vary depending on the size and type of unit, as well as the complexity of the installation. Generally speaking, however, you can expect to pay somewhere in the range of $2,000 to $3,000 for the entire project. This includes the cost of the unit itself, as well as any necessary installation costs. Of course, if you have a particularly complex installation, or if you need to purchase additional hardware to accommodate the new unit, your total costs could be even higher. However, in most cases, the savings you’ll enjoy from having a tankless water heater will more than offset the initial investment.

One of the main benefits of tankless water heaters is that they are much more energy efficient than traditional storage tank water heaters. This is because tankless water heaters only heat water when you need it, rather than keeping a large tank of hot water on standby at all times. This can lead to significant savings on your energy bills as well as reducing your carbon footprint.

Another benefit of tankless water heaters is that they tend to have a much longer lifespan than traditional storage tank water heaters. This is because there are no internal parts that can rust or corrode over time, and they are not subject to the same thermal stresses as storage tank water heaters.

If you are considering switching to a tankless water heater, it is important to consult with a qualified plumbing or HVAC professional to ensure that your home’s electrical and plumbing systems are compatible with this type of water heater. O’Grady Plumbing offers a free consultation, so you can always drop in and get your inquiries attended to.
