If you’ve decided to replace your old water heater, you’re probably wondering how much it will cost to install a new 40 gallon tank. There are a lot of factors to consider, such as the type of tank you’d prefer – gas or electric? – as well as the permits required. Luckily, there are a few things you can do to keep the costs to a minimum.
Gas or electric
Depending on the size of your home, gas or electric 40 gallon water heater installation costs can range from $320 to $1,700. A 40 gallon model is suitable for most homes, with space for two people. Installation costs for a larger, 80-gallon model can run up to $3,200. Gas water heater installation is typically more expensive than electric, but it’s cheaper than electricity.
The cost to install a 40 gallon gas water heater can range from $370 to $1,500. Gas water heaters require vents, which can add to the total installation cost. On the other hand, an electric water heater requires a separate circuit breaker and a dedicated 240-volt electrical system. Gas water heaters require a professional to install them, which can increase the total cost.
The cost to install a water heater may include incidental materials. Additional costs for plumbing and electrical wiring are likely to be involved. In addition, you’ll need to pay for gas or water lines. Depending on the type of fuel, you may need to add an expansion tank. These tanks are essential for safety, as they prevent excessive pressure when water is heated. In addition, the installation of a new water heater may require new electrical wiring, which can cost as much as $1,500.
If you decide on a gas-powered model, you’ll need to make sure that the venting is correctly located. A power vent water heater costs about $500-$1000 more than a direct vent unit. The latter requires additional electrical work and wiring that can add hundreds of dollars to the cost. Finally, you’ll need to pay for a vent stack, which adds up to another $500-$600 to the overall cost.
In addition to flow rate, another important consideration for new water heater installation is the first-hour rating, which tells how much hot water the unit can reliably supply. For example, if your family of four uses 40 gallons of hot water when getting ready in the morning, an 80-gallon model won’t be enough. You’ll need a larger model with a higher FHR to meet your family’s needs.
Tank-style or tankless
When it comes to the installation cost for a tank-style or tankless 40 gallon water heating system, a few things need to be considered. Most homes do not have the AMPs necessary for an electric tankless system, so you will need to have 4 separate 40-amp breakers installed. This can run you several thousand dollars. Alternatively, you can hire a plumber or a contractor to perform the work for you.
The difference between a regular and a tankless water heater is the amount of space it takes up. Tankless heaters are more energy-efficient than traditional storage units, but you will pay for this extra space when you decide to install one. Tank-style water heaters can leak as they age, so if you go away on the weekend, you should consider a tankless model. It also doesn’t store water, so it’s much more energy-efficient and saves money.
While installing a tankless model is easier and cheaper than installing a tank-style water heater, the upfront cost will be higher than the latter. Electric models may cost less, but they can be more expensive to operate depending on your local electricity costs. Solar-powered water heaters cost the most to install, but they’re also more environmentally friendly. Despite their high price, solar-powered water heaters offer low up-front costs and require no maintenance and are free of charge.
While tank-style water heaters can be used throughout the year, they don’t store gallons of water. Instead, they heat water as it enters the system. Flow rate is a key factor in determining the system size that is right for your home. Add up the number of appliances and fixtures you have in your home, and figure out how much water you use. Then figure the total GPM of these appliances. Those that are independent of each other don’t count toward the total GPM.
In general, the installation costs of a tank-style or tankless 40 gallon water heating system vary. For single-family homes, a whole-house tankless water heater may be enough. Similarly, a single point unit can be sufficient if you only need hot water for the shower or sink. If you’re in a small apartment, you may want to opt for a tankless model instead.
Before installing a new water heater, make sure to check with your local building jurisdiction. Some areas require permits for electrical and plumbing changes, and a water heater can cause problems if it doesn’t meet current code requirements. Gas lines may also need permits, since they can explode if they’re not installed correctly. In addition to the local codes, there may be other statewide codes that must be followed.
The Building Division also requires a permit to install a water heater, and is often the place to go for such an inspection. In Atlanta, for example, some counties require sellers to obtain a certificate of compliance prior to selling an item. The inspector will inspect the installation to ensure that it follows code and does not pose a fire hazard. In some areas, the government has increased spending on water systems, and some cities have begun improving theirs.
Plumbing permits for water heaters are required when installing a new water heater, as well as when replacing an old one. Permits are usually inexpensive and simple to obtain. Building departments can provide a handout that outlines the process, and are happy to answer any questions you may have. In addition to building permits, electrical permits may also be required if you’re making any changes or modifying your home’s electrical system.
The only exception to the requirements is if you’re installing a water heater in an attic. For this type of installation, you’ll need an attic with an access way that is sized at least three times the width of the largest component. A standard 40-gallon water heater should be accessible from the attic through an opening at least one foot above the roof. You’ll also need to create a platform that’s 30 inches by 30 inches. You’ll also need a permanent 120-volt receptacle outlet and lighting near the appliance.
Some other projects require a permit for a 40-gallon water heater installation. Some of these involve moving an existing water heater or changing its location, and these also require a permit. If you plan to relocate a heating unit, you’ll need to modify the gas lines, install new drains, and vents. In addition to this, you’ll also need a permit for installing an accessory dwelling unit.
The materials used in a 40-gallon water heater installation cost are a major factor in determining the total cost. These are made from a variety of different materials, including high-density polyethylene polymers (HDPE), fiberglass, and galvanized steel. The internal lining and external insulation of the tank also contribute to the price. Some models have high-quality glass linings, while others use stainless steel or other corrosion-resistant materials. Additional plumbing is also required, which can cost between $8 and $10 per linear foot.
Depending on the model, a 40-gallon gas-powered water heater installation cost can range anywhere from $350 to $1,500. The installation of a gas water heater requires a vent stack and additional wiring, which can add to the overall cost. Electric water heaters, on the other hand, require a dedicated 240-volt electrical system with a separate circuit breaker. A 40-gallon water heater installation cost is significantly higher than that of an electric model.
In addition to pipe fittings and discharge pipes, a water heater installation also requires additional incidental materials. These materials can include solder, pipe thread compound, gas or water piping, and gas connectors. Additional materials may also increase the total cost of a water heater installation. So be prepared to pay extra for installation. If you’re going to hire someone to install your water heater, take the time to research the costs of the materials used in a 40-gallon water heater installation.
