How to Install a Tankless Water Heater: A Complete Guide

Tankless hot water heaters have changed how we get hot water. Unlike regular tanks, tankless heaters give you hot water when you need it. This saves space and saves energy. 

This guide will help you how to install a tankless water heater, pointing out important steps and tips for a good setup. If you feel unsure about doing this yourself, think about contacting experts like Aquilina Plumbing and Rooter.

Before starting with the installation process, it's important to know why many homeowners choose tankless water heaters. These units:



• Provide endless hot water so no one in the home has to wait for the tank to refill.
• They save energy because they heat water only when you need it, which can lower your energy bills.
• Have a small, stainless steel design that saves space and adds style to your home.
• Need less care compared to tank-style systems, which means lower costs over time.
• Last longer than regular water heaters, making them a smart choice for your property.
  

Tools and Materials Needed for Installation

Make sure you have these tools and materials ready before starting:

• Screwdrivers
• Adjustable wrench
• Pipe cutter
• Heat-proof sealant
• Stainless steel venting parts
• Gas supply line pieces
• Electrical wiring (if needed)
• Tank for extra air
• Pressure release valve
• Measuring tape and level

Using the right tools and materials makes the installation easier. It also helps to lower the chances of mistakes.

Step-by-Step Installation Guide

1. Remove the Old Water Heater

Start by turning off the water supply and the main water source. Then, disconnect the water and gas supply valves and the power sources. To drain the old unit, open a hot water faucet and let the water run out completely. After it's drained, disconnect the water line, gas line, and electrical connections. Be sure to throw away the old unit according to local rules.

2. Choose a Location

Select a spot for the new unit that follows the tankless water heater installation guide from the maker. The area should have enough airflow and easy access to care. Make sure the wall can hold the weight of the water heater. Think about using a black iron pipe when looking at how close it is to water and gas lines. This can lower the need for big plumbing changes.

3. Mount the Tankless Water Heater

Attach the unit to the wall with the brackets given. Follow the instructions carefully for proper placement and stability. Use a level to check that the unit is straight and tightly secured. This will help avoid any problems while it is in use.

4. Install the Exhaust Vent

For gas-powered units, it is important to install the exhaust vent right. This helps to safely send gases out through the outside wall. Use stainless steel vent pipes and other parts made of stainless steel. These are sturdy and safe to use. Make sure the vent system meets local building rules and the maker's guidelines. Good venting is key to stopping dangerous gases from building up in your home.

5. Connect Water Lines

Attach the cold water line to the unit's inlet and the hot water line to the outlet. Connect them to the water heater valves. Use a pipe cutter to get good fittings. Use a sealant that won’t break down with heat to stop leaks. It is also a good idea to put in a pressure relief valve and a tank to handle changes in water pressure. Check all connections to make sure there are no leaks or loose fittings.

6. Connect the Gas Line or Electrical Supply

• For Gas Units: Install the gas supply line and upgrade your line if you need to meet the higher demand. Use a soapy water solution to check for leaks. Make sure your gas line is the right size and installed to meet the unit's needs.
• For Electric Units: Make sure the unit is connected to a dedicated circuit breaker that follows local electrical rules. Good electrical connections are important for safety and to work well.

7. Purge Air from the Water System

Before you turn on the unit, remove air from the water pipes. You can do this by opening all the faucets in your house. Let the water run until it flows steadily and has no air pockets. This step helps the system work well and stops damage to the purge valve and the unit.

8. Test the System

Turn on the water supply and look for leaks. Power on the unit or light the pilot flame for gas models. Open a hot water faucet to see if the system is working well and giving hot water when needed. Watch the unit for a few minutes to make sure everything is working smoothly.

Can you put a tankless water heater in any house?

Yes, you can install tankless water heaters in most homes. However, you need to think about things like water habits, electricity levels, and room size. It is a good idea to talk to an expert to see if a tankless water heater will work in your home.

Common Mistakes to Avoid

• Not upgrading your gas line when needed can cause poor performance and safety risks.
• Skipping the pressure relief valve may lead to damage and safety issues.
• Mounting the unit wrong can create problems with operation or safety.
