The first things that affect the price of your installation are where it will be placed and what type of plumbing your home requires? Some homes need extensive reworking for their hot water system before they can accommodate a tankless water heater.

Size of Your Home

The size of the house also plays a role in why tankless water heater installation is so expensive. A small or medium-sized house may require only one unit. But larger homes need multiple units to provide enough hot water for everyone at once. The more units you have to install, the more expensive it will be.

Cost of the Unit

Of course, why tankless water heater installation is so expensive has a lot to do with the price of your unit itself! If you purchase your unit for cheap or secondhand, expect that money to show up in your installation costs. Just like buying anything new, purchasing an energy-efficient product comes with a higher price tag.

Type of Plumbing You Have

The final question is why tankless water heater installation is so expensive; the question can be answered by looking at what type of plumbing you have in your home. Suppose the place where the unit will be installed doesn’t currently have any hot water. Then you’ll need to install new piping. You can expect either a higher or a lower cost depending on the type of construction of your home.


The next thing that affects installation price is the type of system you require. Gas systems are typically less expensive than electric. But it depends on where you are living and what energy sources are available to your home. Suppose the electricity in your area comes from renewable or green sources like solar or wind power. Then an electric system may be cheaper in the long term.

Get an accurate estimate

The more information you have about your home and the unit. The easier it is to get a realistic estimate of the cost. If possible, coordinate with an installer before purchasing your water heater so that they can provide you with a rough idea of what installation will look like.

Then they will likely charge more for their services than someone who works directly for the company that makes your tankless water heater unit if you want to be sure that your installation is done right. If so, you might need to look for someone with more experience.

The size of the water heater
