Top 6 Benefits Of Installing a Tankless Water Heater Outside Your Home

Are you thinking of installing a tankless water heater outside the house? Whether it is something you have been mulling over for a long time, or something that just crossed your mind today, it is worth considering the top 6 benefits of installing a tankless water heater outside or in your home. 

It is a perfect idea if you have a backyard or a garden you often turn into a party space, regardless of the season. Tankless water heaters are also a fantastic option for those living the van life and for those completing DIY projects in small spaces.

If you have been thinking about buying and installing an instant heater for your backyard, here are a few benefits that might encourage you to make the investment. 

1. Lower Energy Consumption

The best part about using tankless water heaters is their instant heating mechanism. Unlike traditional water heaters, these devices do not come with a tank to store hot water for a long time. Instead, tankless varieties heat the water on demand.

Whenever you need hot water, you can switch the device on and the water supply through the device will get heated instantly. This means that you do not have to keep the device functioning for several minutes before you need hot water.

The energy required to heat the water inside the device is lower for tankless heaters. From an environmental perspective, tankless water heaters are a better choice since they save a lot of energy that would otherwise be wasted. 

With tankless water heaters, you have the freedom to get hot water when you need it. Best of all, the device doesn’t require a power supply. This is something that will come in handy time and time again. 

2. Lower Utility Bills For Using a Tankless Water Heater Outside

With modern tankless water heaters, you can save a lot of energy and money at the same time.  Since they are smaller and more efficient, tankless water heaters use quite a bit less energy than traditional water heaters. Because of this, they can help you save on your electric bill and help conserve the planet a little more every day. 

A wise, small investment today can mean big financial savings in the future thanks to this small appliance. If you take into consideration the price of the tankless heaters minus their utility bill reductions in the long term, the economically (and environmentally) wise decision quickly becomes obvious. 

Depending on where you live, you might even get a utility incentive for using an electrical appliance with an energy star rating. Most traditional water heaters lack this unique distinction. This means that replacing your old water heater with a new instant heater is the obvious choice. 

Considering that tankless water heaters are so efficient, they are a great option for heating water both inside and outside of your home.

3. Longer Life Span

Durability is another factor that makes tankless water heaters excellent for homeowners. When you buy electric appliances, longevity is typically one of the key concerns. 

We now know from above that tankless water heaters are more efficient, but one question remains: are tankless heaters both efficient and durable?  A tankless water heater generally performs better than a traditional one with a storage tank.

It is easier for a tankless water heater to operate than it is for a traditional water heater to operate. This means that there is less constant wear on the appliance itself.  These water heaters are durable and built to last. 

There is less surface area subject to damage, and it is easy enough to determine what needs fixing if anything goes wrong with a tankless water heater. Since they are smaller, they are easier to handle and fix, extending their lifespan that much further into the future. 

4. Major Space Saver

If you put all technicalities aside and think of the physical appearance of a tankless water heater, there are some significant differences to weigh. Tankless water heaters are typically much smaller than traditional water heaters with storage tanks. They are often much sleeker than the average traditional water heater as well. 

Tankless heaters are very convenient and easy-to-install alternatives you can choose to use at any time. A narrow wall or a pillar will be enough to hold an instant heater in place, making them as great a choice inside the house within a cabinet as they are out in the great outdoors. 

5. Endless Hot Water Supply

Have you ever run out of hot water while taking a shower? Getting shocked by the touch of chilled water after the last drop of hot water stored in the tank gets drained is a common experience for many. With tankless instant heaters, you can never experience that great tragedy again. 

The entire heating mechanism of the instant water heaters relies on an on-demand supply of hot water. As long as you keep the device on, it will keep supplying you with hot water and continue assessing your requirements. It is more like a steady supply of hot water rather than taking the stored hot water out of the tank and then waiting for the round of heating.

Therefore, with tankless water heaters, you get a constant supply of hot water for as long as you need. Additionally, when the water heater with a storage tank grows old, its capacity to retain the water inside the tank reduces.

This means that the water stored inside the tank gets colder easily. To fix this, you have to switch on the device frequently for heating the same water, wasting energy.

With the latest instant water heaters, you do not have to worry about any of this. Switch on the device and a steady flow of hot water will come out of the hot water faucet. 

6. Less Maintenance

Another factor that makes water heaters without tanks more user-friendly is their low maintenance requirements. However, you should follow all the cautions and standards while installing it.

The manufacturer’s manuals generally offer a detailed idea of where you should place the machine, what the gas line size is for a device and any other information you might want. Hire an expert for the task and install the machine following every rule and guideline to enjoy on-demand hot water

Compared to traditional heaters, tankless water heaters come with long service life. The mechanism and technology used for making the heaters remain advanced and require little to no maintenance. 

However, if you find any problems with heating, you can hire expert help for a thorough inspection of the device.  Generally, though, you do not have to bother about anything at least for the first 10 years since they are such reliable appliances. 

If you feel the need to, you can use a wooden box to keep the device safe and protected for a long time. Additional installation and special gas lines are not necessary for these devices. If you already have a gas line functioning for the old heater, you can use it for the new one.

At the same time, it should be noted that you should never miss out on checking the gas line size before installing the new one. If the existing gas line is perfectly suitable for the instant heater, you do not have to invest in new gas lines. Otherwise, for the sake of safety, you will need to install a new one. 

Hire an expert with enough experience in electric circuits and plumbing work to get the installation done flawlessly. As long as your device remains accurately grounded, you do not have to bother much about anything else. Your tankless water heater will be ready for use inside or outside your home before you can believe it. 


Gone are the days when bulky water heaters with storage tanks crowded the washroom space and were inappropriate for open spaces. We’ve entered into the age of tankless water heaters. Now, the opportunities for heating water outside (or inside) are seemingly endless. 

The new-era sleek water heaters look smart, consume less space, and work more efficiently. Install a tankless water heater outside or in your home to enjoy a seamless supply of hot water anytime you need it.
