If you are worried about the price of installing a tankless water heater, then you might consider installing your unit yourself. A lot of homeowners today are making the shift to tankless water heaters since going tankless has a lot of benefits over using the traditional tank version.
For one thing, a tankless heater has a longer life span than most traditional tank units. Since they don’t come with a 40 or 80-gallon tank, a tankless heater is also ideal for smaller homes where they can be installed in confined spaces, such as closets or even under the sink. Tankless units also consume less power since it only heats up water upon demand; this translates to lower energy bills. Lastly, you don’t have to worry about leaking tanks which is always a plus.
The costs of installing a tankless water heater can vary depending on the plumbing company you hire for the job. However, if you have some DIY skills then the following installation steps should help you have your new heater up and running in no time.
6 Steps for Tankless Water Heater Installation
- Remove the old unit and prepare the installation site for your new one.
If your old water heater is still in place, then the first step would be its removal. Start by turning off the water supply and disconnecting it from the supply line. You may want to place a bucket under the supply line since there is probably some leftover water left in the pipe. Next, disconnect the unit from its power source. Gas heaters have valves that you have to turn off while an electric version can be simply unplugged from its power outlet. Check the water heater disposal rules in your area and discard your old unit accordingly.
- Install a new gas supply line.
Once you have decided on the location of your new tankless water heater, you will need to install a new gas supply line for the heater. It is possible to use the existing gas line in your home, but chances are you will need to install a T and valve in your gas line as well as a new supply line made of corrugated stainless steel.
- Install the new water supply lines.
The next step in installing a tankless water heater is putting the new water supply lines in place. These pipes are typically made from copper and is coated with flux before they are soldered together. Bell-hanger brackets are used to hold the water pipes in place and to prevent them from coming into contact with walls.
- Mount your new tankless water heater.
Once your gas and water supply lines are in place, you can now mount your tankless heater on the wall. If you’re handy with tools or you have some carpentry know-how, you can also opt to build a platform on your wall so you can mount the water heater on it, instead of directly on the wall.
- Hook up the heater to the gas and water supply.
Once the tankless water heater is in place, you can now connect it with the gas and water shut-off valves. Make sure you tighten the connections properly with a wrench. Otherwise, gas and water may leak out. Connecting the heater to the water supply line may require you to do more soldering of the copper pipes.
- Attach any additional parts and turn on your tankless water heater.
Depending on the tankless water heater model that you purchased, you may have to install other necessary parts other than the basic gas supply line, water supply line, and the tankless heater itself. For example, some water heaters come with a vent piping.
Once you have completed the installation, procure some pre-cut insulation pads that you can use to protect your hot water pipes. Next, plug in your heater, turn on the gas and start enjoying a steady supply of hot water anytime you need it.
Before you install your tankless water heater yourself, make sure you carefully read the heater’s manual. Some water heater manufacturers void the warranty if the heater is not installed by a licensed plumber.
