Practical Steps on Selecting a Gas Tankless Water Heater

Since a gas tankless water heater is a significant investment, it is vital to tie all loose ends before making a selection. As a result, we have the following tips to guide in selecting a tankless gas water heater.

1. Installation Needs:

Before you choose a gas tankless water heater, it is vital to ensure that your gas supply line can handle the extra demand. This is vital to the smooth operation of the unit.

a) Venting requirements:

There are many top tankless gas water heater brands in the market. This translates to the fact that venting requirements will vary. Keep the following in mind before selecting a gas tankless water heater

  • Select category III stainless steel (UL1738 certified) venting.
  • Check the local building code to make sure you meet all requirements.

 b) Venting Needs:

there is a big chance your gas tankless water heater will come with venting kits. Hence, be sure to check this to be confident that you have all the requirements. Depending on the specific point of installation, the chances of the venting accessories meeting your needs are pretty low.

As a result of this, endeavor to know the length and other dimensions of your vent routes, and the paths of the discharge via the walls.

Also, there is a possibility you might need an electrical connection for your gas tankless water heater. Be sure you understand the basic requirements of the unit you are buying so that your house electrical system will be able to serve it

2. Location and Mounting Space 

A tankless water heater can be mounted anywhere depending on the application type. Since they are small in size, they do not need a particular location for installation. You can install them in the closet, under the stair and even outside as long as it is safe from the elements (debris, pets, kids, direct sunlight and splashed water)

If you had a traditional water heater that you uninstalled, we recommend installing your new unit at the same point. This will allow you to reduce installation cost and use some critical accessories of the old unit.

In selecting a location, you need to consider the plumbing configuration of your house. The point of installations should not necessitate significant plumbing change or alteration. The essence of this is to cut cost. The point of installation should also be central to the various points that demand hot water. This is to reduce the distance hot water will travel thereby reducing temperature loss.

3. Size and Demands

Before choosing your gas tankless water heater, it is vital to know the flow rate, alongside the desired outlet water temperature. The following steps can help you size your gas tankless water heater correctly:

Step 1: Calculate the Total Flow rate 

The accurate value of the flow rate is essential which is a factor of the maximum number of the device that will serve the tankless gas water heater. When you know the individual values of these devices, add them up. The value should correspond to the flow rate of your gas tankless water heater

For instance, assume you will run two laundry rooms with flow rates of 1.8 gallons per minute with a shower rate of 2.3 gpm. The minimum flow rate of your ideal tankless water heater should be 5.9 gallons per minute.

Step 2: Determine the Desired Temperature Rise

An idea of the temperature at the various points of use is essential to determine the needed temperature rise. You will subtract the desired outlet temperature from the outlet water temperature. As a rule of thumb, you should assume a temperature rise of 50F. With this, you will not have to undersize your gas tankless water heater.

People dwelling in areas with a warm climate will have a higher incoming water temperature, with an outlet water temperature around 100 to 1100F. Your tankless gas water heater should give a temperature rise of about 55F

Step 3: Calculate the Desired Flow rate

You need to know the amount of water you need. If you have a laundry and a shower that you will probably use simultaneously, you need to know the combined flow rate. The chart below shows the range of water usage alongside the average temperature for the various faucets in the house.

Fixtures Average Flow (GPM) Average temperature (Faharient)
Tub 4.0 102
Shower 2.5 – 3.0 104
Washing machine 2.0 120
Dishwasher 1.5 110
Kitchen Sink 1.5 110


With the above, if you want to run two showers at the same time, you need about 6 gallons of water per minute. If you are running the bathtub and a dishwasher, you will need a flow rate of 5.5 gallons per minute.

All in all, your aim should be getting a tankless water heater that will meet your need in terms of the flow rate and possibly exceed it a little. Under sizing your tankless water heater is not a good idea.

How Much does it Cost to install a gas Tankless Water Heater? 

Many households that have installed the gas tankless water heater reported that the total cost of installation is between $982 and $2,862.

There is no specific price because most tankless gas water heaters as well as households come with different requirements.

A plumber could bill you between $45-$150 per hour.

One thing to note is that the average installation cost range includes various accessories that are necessary for specific models and households. Some examples are venting accessories, gas connector kit, mounting hardware, and a lead-free brass valve set to name a few.
