Installing of the Tankless Water Heater

How Much Does It Cost to Install a Tankless Water Heater

People have been switching to tankless water heaters for some time now, due to the many benefits brought to the table.

Even if the price may be twice and ever three times than the cost of traditional water heaters with tanks, tankless units are worth every single point when they fit the application.

Just to give you an idea, the installation of a tankless water heater can cost you from $1,400 to $2,500. It depends on many things, and when your house needs rewiring, you may have to pay up to $3,000.

How much do people typically pay for installation?

The moment you know that a tankless water heater is the right choice for your household, you should check the installation costs too.

Here are some numbers to look at:

  • Minimum cost- $600
  • Maximum cost- $1,400
  • National average price- $1,985
  • Average range- $1,470-$2,510

Traditional water heaters with the tank are losing ground as we speak, as people finally realized that having hot water on demand endlessly for less money is great. The only thing to worry about is the costs that add to the price of your tankless water heater!

What impacts the installation costs?

The majority of customers will pay somewhere between $1,470 and $2,510 for installing the new tankless water heater. The most significant aspects to impact the final costs are plumber’s work and the heating equipment you’re going to use. Don’t forget that you also need to buy some parts and materials required for the proper installation.

Speaking of which, it’s the gas-fired models that need venting, and therefore, several accessories. The gas connector kit, 2-piece brass valve set, a vent kit, mounting hardware, and some fittings will increase your costs. To give you an idea, you may spend $50-$100 for a vent kit, whereas $10 per foot should be enough for piping and insulation.

How much will you pay for professional plumbing?

Unless you’re a professional plumber, it’s better that you avoid installing the tankless water heater on your own. Even if you’re the DIY kind of person, you may still void the warranty when not installing the unit professionally.

Having said that, let’s note that you may pay somewhere from $50 to $125 per hour for a plumber. A straightforward install that doesn’t require running any other gas lines to the new unit should take 3-4hours. The installation may cost you somewhere from $150 to $600.

If you already have a water heater and you need to get rid of it, you will pay more. It’s the same when your household needs new or structural updates for the new unit.

If you go with a gas-fired model and have no gas hookup at the house, you will have to mount one for the new tankless water heater. Running a new gas line to a home is $500 for most regions.

You also need to make sure that the building is constructed according to the safety regulations for inhabitants. All structure modifications, renovations, or retrofits to the infrastructure must present a permit for providing compliance with the federal and local building, zoning codes, and construction. You will pay $200 to $500 only for the licenses.

Tankless or tank?

Installing a traditional tank water heater may cost you from $650 to $1,611 since the unit is cheaper and easier to install.

Also known as “boilers,” traditional tankless water heater is a common choice and has been around for more than a century. They can work for central heating and heat the water for the whole house. The main downside is the ample space they require for storage, so give it a good thought before choosing one of the two.

Should you go with a gas-fired unit or electric model?

You will pay more for a gas-fired unit, especially when considering the installation. Gas models also require venting and several accessories, which only increase the initial investment.

However, a gas-fired unit needs less fuel to operate, but the amount of gas required for the pilot light impacts the operating costs too. You can always cut down the gas usage by using a unit with intermittent ignition and not a pilot light.
