tankless water heater installation

Tankless water heaters are becoming more popular for homeowners looking to update their home’s amenities. However, installing a tankless water heater entails more than just replacing the old system with the new one since installation and pre-installation considerations for operation and compatibility are sometimes necessary.

They have many benefits over traditional water heaters, but there are some things you should consider before installation. Here are the most important factors to consider about a tankless water heater installation.

Installation Cost

The installation price is another financial factor when purchasing a tankless water heater. Tankless water heaters can be 2-3 times more expensive than traditional heaters. Fewer plumbers are competent in installing tankless water heaters since they are much more complex.

Additionally, most tankless water heaters need a gas hookup to function. The cost will also depend on the size and type of heater you choose and whether you need to modify your home’s plumbing or gas lines.


Proper ventilation is critical when installing a tankless water heater. Most models require special direct-venting, meaning the installation process can be more complex and expensive.

Avoid carbon monoxide leaks using Category III stainless steel venting material for all tankless water heaters. It is the only type of venting material that meets the American National Standards Institute (ANSI) standard for tankless water heaters. Make sure you factor in the cost of any necessary ventilation upgrades when budgeting for your new water heater.

Water Pressure and Flow Rate

Tankless water heaters work by heating water on demand, requiring a high water pressure and flow rate to function properly. The minimum water pressure required is typically between 10-25 psi.

If your home doesn’t have adequate water pressure, you’ll need to install a water pressure booster pump, increasing the installation cost. Additionally, if your municipality has low water pressure, you may not be able to use a tankless water heater at all.

Another critical factor is the flow rate, which is the water the heater can deliver in a given period. Most tankless water heaters have a flow rate between 4-8 gallons per minute (GPM).


Since they are often installed on a wall, tankless water heaters are smaller and require less energy to heat and transport water. Tankless water heaters slowly heat water than traditional ones because hot water is not always kept in a tank.

Tankless water heaters are less likely to run out of hot water than traditional heaters since they heat water on demand. It can be a major convenience if you often have large groups of people over or if you have a big family.

You’ll never have to worry about taking a cold shower again!

Energy Efficiency

One of the main reasons people switch to tankless water heaters is for energy savings. Tankless water heaters can be 24-34% more energy efficient than traditional storage-tank water heaters.

This efficiency translates into lower energy bills and a smaller carbon footprint.


Tankless water heaters typically have a longer lifespan than traditional storage-tank water heaters. With proper maintenance, tankless water heaters can last 20 years or more.

It is because tankless water heaters have fewer moving parts and are less likely to break down over time.


Installing a tankless water heater can be a great way to save money and energy in the long run. However, there are a few things you need to consider before making the switch.

When budgeting for your new water heater, make sure to factor in the cost of installation, ventilation, and water pressure. Additionally, keep in mind that tankless water heaters have a slower flow rate than traditional heaters.

With proper research and planning, installing a tankless water heater can be a great way to update your home.
