Why Should You Get a Tankless Water Heater?

  1. Constant Access to Hot Water

If you’ve ever taken a warm shower that abruptly turned chilly, it was probably due to a tank water heater exhausting the hot water it had stored. Tankless heaters, also referred to as on-demand water heaters, deliver hot water as required. These heaters employ a burner or heating element to swiftly warm up cold water as it travels through the unit when the hot water tap in the house is switched on. This reduces energy waste by heating water only when necessary. 

  1. Less Room

If you have a small home, going tankless is undoubtedly the best option. Tankless water heaters do not keep water in storage, as implied by their name. as needed, rather than storing hot water in a conventional tank. Tankless water heaters are wall-mounted, in contrast to conventional tank models. Tankless heaters can easily be put in homes with limited space due to their small size. They range in size from 30-80 gallons, but on average they are about two feet tall and a little over a foot broad.

  1. Less Dangerous Concern

A tankless water heater’s lower danger of leaks, damage, and safety issues is only one of the many advantages of purchasing one. Tankless types are often safer because they heat on demand; there isn’t a big holding tank that could overheat or explode. The majority of tankless types have sensor monitors that can turn off the heating element if it becomes too hot.

  1. A longer life span

The lifespan of tankless water heaters is almost twice as long as that of conventional tank heaters! Tankless heaters can last up to 25 years, compared to the 8 to 12 years that regular heaters typically survive. These heaters last longer for a variety of reasons, including fewer corrosion, silt buildup, and leakage.

  1. Planning ahead

In addition to having a longer lifespan, tankless heaters are around 24% to 34% more cost- and energy-efficient than storage tank heaters. Tankless heaters may cost a little more up front than conventional storage heaters, but there are a few advantages to switching over, including larger storage space, unlimited hot water, and cheaper energy costs.

                      Lifespan of Tankless Water Heaters

Tankless water heaters are more durable than tank water heaters since they are built using sophisticated technology. The heaters have a 20-year lifespan as a result.

A tankless water heater can, however, last for more than 30 years with careful care. Because they can rapidly heat water, tankless water heaters are also known as “on-demand water heaters.”

They only operate when you need hot water, extending their life. Additionally, they corrode more slowly than tank water heaters do.


  How to Locate the Perfect Spot for Your Tankless Water Heater

Tankless water heaters can sometimes be installed in more places because they are typically smaller than their conventional equivalents. The effectiveness of your tankless water heater will be impacted by where you install it. To locate the best location for your heater, examine the following variables.


The temperature has an impact on a tankless water heater. The water within will freeze in colder temperatures. This could result in significant harm that your warranty might not cover. It is preferable to install a tankless heater indoors for this reason. The heater’s freeze avoidance mechanism will need continual power to operate if you want to install it outside.


Your tankless system shouldn’t be set up in a place where there is a lot of dampness or where liquids could spill on it. Moisture has the potential to corrode the burner and limit gas flow, resulting in system failure.


Your heater should be placed in a clean, clutter-free area. Aerosol particles and other pollutants might clog your heater’s air vent, hinder the fan’s operation, and result in insufficient gas combustion.


Future maintenance should be taken into account when choosing a suitable location. Install the heater at a location that is simple to get to. It makes the most sense to install the tankless system in the same location as your old water heater if you’re replacing one.

Demand Regions

The demand regions in your home should be close to where you install your tankless water heater. The time it takes for the hot water to get from your heater to those locations will be shorter the closer it is. Water and heating energy will be conserved.    

                    How to Select the Right Size Tankless Water Heater

Step 1: Establish the maximum number of devices you intend to use and the combined flow rate of those devices. Afterward, total their flow rates (gallons per minute). For the demand water heater, this is the ideal flow rate.

Step 2: Calculate the necessary temperature increase. Subtract the target output temperature from the desired entering water temperature to find the temperature rise.

If you live in a warm climate your water temperature will likely be much higher.) For most uses, you’ll want your water heated to around 105–115°. In this example, you’d need a demand water heater that produces a temperature rise of 55°.

Step 3:

Sizing Example: An average shower will be between 104–106° and uses 2.6 gallons of water. Assuming your water temperature is 40° coming into your home, and you want to produce enough hot water to run 2 showers at the same time, what temperature rise would you need to produce to accomplish this?
