How Much Is A Natural Gas Water Heater?

The typical cost of replacing a water heater is $1,200, which includes the cost of the new unit as well as labor.

What is the cost of a 40-gallon hot water heater for your home?

Water heater installation involves more than simply the water heater itself. Take a look at the following common factors.

  • The position of your water heater in your home will have an impact on the labor costs. If the water heater must be installed in a basement or a difficult-to-reach section of the attic, for example, the installation cost will be higher.
  • Electricity venting: As previously said, power venting can cost anywhere from $600 to $1,100. Direct venting might add anywhere from $500 to $1,000 to the cost of your installation.
  • Size: The number of people in your home determines the size of your water heater, and prices rise as the size increases. A 40-gallon water heater may successfully cover the needs of a two-person household and costs between $320 and $1,600. A 75-gallon (average price of $900 to $3,000) or an 80-gallon (average price of $1,000 to $3,200) water heater may be necessary for homes with five or more occupants.
  • Water heater installation necessitates the use of a range of materials, including venting pipes, pressure valves, water and gas pipework, thread compound, solder, and other items. For more intricate installations, a skilled installer may utilize additional materials.
  • Local permits (if required): Depending on the location of your home, local permits may be required for water heater installation. These permissions can sometimes be purchased for a fee.
  • Expansion tank: For your installation, a professional installer may remove an expansion tank. This tank is built to withstand water’s thermal expansion while also preventing excessive water pressure. Expansion tanks range in price from $40 to $150.
  • Price of tank removal: An installer may charge extra to remove an old water tank.
  • If you need a water heater relocated or converted from one fuel type to another, the cost varies substantially. It can cost as little as $200 or as much as $10,000 to relocate a water heater. Converting your water heater’s fuel type might be pricey. Switching from electric to gas, for example, necessitates the construction of new gas lines, which might cost an additional $1,500$2,300.
  • Carpentry work (if required): Carpentry work may be required depending on what your water installation demands, such as removing or adding woodwork in your attic to fit a heater. This increases the cost of labor and the number of hours worked.

What is the average lifespan of a gas water heater?

A water heater’s life expectancy is estimated to be eight to twelve years based on the manufacturer’s recommended service life. This varies depending on the unit’s location and design, as well as the quality of the installation, the maintenance schedule, and the water quality.

Is a natural gas water heater less expensive than an electric water heater?

Standard water heaters, by far the most prevalent option, heat water using a gas flame or an electric heating element.

Gas water heaters are often less expensive to operate than electric water heaters, depending on your local utility bills. They’re also more expensive up front than an electric car. However, based on energy savings, gas heaters often pay for themselves in approximately a year.

Gas ranges from $300 to $600; electric ranges from $250 to $500. The cost of installation ranges from $700 to $2,000.

  • Have a capacity of 20 to 80 gallons (However, surprise! The most crucial factor isn’t the gallon capacity. Rather, it’s a performance metric known as first-hour rating. (See below for more on the first-hour rating.)

When should you replace your hot water heater?

Nothing, least of all a water heater, lasts forever. During the course of a typical home’s occupancy, a resident will almost certainly need to replace a water heater. The problem is that most homeowners are unaware when their water heater is approaching its end of life. Not knowing this, on the other hand, can put you in serious danger if your heater breaks down due to age.

How Long Do Water Heaters Last

Water heaters typically survive between eight and ten years. While it is typically advised that heaters be replaced at the age of 10, the necessity to do so may occur before or after this time frame. Whether or not a heater begins to display symptoms, it should be replaced after ten years from the date of manufacture.

Signs of a Bad Water Pump

If a water heater exhibits the following symptoms, it should be replaced immediately:

Water heaters do not all have a ten-year life expectancy. The sole exception is gas water heaters, which only last six to eight years on average. As a result, if you only live in a home for seven or eight years, you’re likely to be liable for replacing the water heater if it’s gas-powered.

Serial Number

To find out how old your water heater is, look for the serial number on the manufacturer’s sticker, which is normally located on the upper side of the tank. The number, on the other hand, does not display the date in a format that is easily recognizable. Instead, you’ll see a series of digits that look like this:

Each number begins with a letter that represents the month of the year. The letters G, D, and I stand for the seventh, fourth, and ninth months of the year, respectively, so the numbers refer to heaters made in July, April, and September. The first two digits of the year in question are represented by the first two numbers following the letter; hence, the three serial numbers are for heaters with the following dates of origin: 07/2006, 04/2004, and 09/2007.

Which is better: a 40-gallon water heater or a 50-gallon water heater?

With a larger tank, you won’t have to worry about running out of hot water. Water heaters with a capacity of 50 gallons have a longer lifespan. 40-gallon heaters typically last eight years, but 50-gallon heaters can last up to 12 years. Because 50-gallon heaters have thicker tanks, this is the case. As a result, they have a lower risk of developing leaks.

A 50-gallon water heater has a lifespan of 8 to 20 years, which is significantly longer than the average water heater.

An extra ten gallons may not appear to make much of a difference. However, going with a 50-gallon water heater implies going with a more cost-effective water heater.

A 50-gallon water heater, according to experts, is less expensive to operate than a 40-gallon water heater. Furthermore, a water heater with a capacity of 50 gallons is more efficient than one with a capacity of 40 gallons.

American Standard heaters are covered by a four-year guarantee as standard. While this is more than some brands provide, it is far from industry-leading, and if a long warranty is one of your top priorities, there are better options especially given the greater price you would pay for this brand.
