Siogreen Tankless Water Heater Review: Is It Worth The Investment?

As part of running Tankless Heater Guides, I’m always diving into tankless water heater brands and learning about what they offer. I recently came across SioGreen tankless water heaters, and here are my thoughts.

After doing some research, I was impressed with their patented quartz infrared heating system that eliminates the need for metal heating elements, which are often the cause of failure in traditional electric water heaters.

What I found particularly interesting about SioGreen’s tankless water heaters is their ability to reduce lime and scale buildup, which can cause damage to traditional water heaters and require costly repairs. Their quartz tubes and infrared energy technology prevent the buildup of minerals and prolong the life of the unit, making it a smart investment for homeowners and businesses alike.

Features of a Siogreen Tankless Water Heater

Like many tankless water heaters, Siogreen’s provides endless hot water, energy efficiency, and convenience. However, here are some of the features that make the Siogreen Tankless Water Heater stand out:

Advanced Flow Control Technology

Have you experienced turning on a water heater, feeling the cold water instantly turn hot (too hot), then going back down to the expected temperature? Yeah, I hate that too. Great news, you won’t experience that with the Siogreen Tankless Water Heater is equipped with Advanced Flow Control Technology. This technology ensures that the water temperature remains constant, regardless of the flow rate. This means that even if multiple faucets are being used at the same time, the water temperature will not fluctuate. This is especially useful in large households or commercial settings where hot water is needed simultaneously in multiple locations.

Self-Cleaning Technology

The Siogreen’s Tankless Water Heaters have a self-cleaning mechanism that prevents the buildup of mineral deposits. This is important because mineral buildup can cause damage to the heating elements, reducing the lifespan of the water heater. With the self-cleaning technology, they can operate at peak performance for longer periods of time. This means that the water heater requires minimal maintenance. The self-cleaning technology reduces the need for manual cleaning, and the heating elements are easily replaceable if needed.

Easy Installation

The installation process for the Siogreen’s Tankless Water Heaters is straightforward and hassle-free. The compact design of the water heater allows for easy installation in any location. Siogreen provides detailed manuals on how to install your tankless water heater on your own. But you can also easily find a professional contractor to help you with the installation if needed.

Remote Control

The Siogreen Tankless Water Heater comes with a remote control that allows for easy temperature adjustments. The remote control also provides diagnostic information, making it easier to troubleshoot any issues that may arise. This feature adds convenience and ease of use to the already impressive list of features of the Siogreen Tankless Water Heater.

Benefits of a Siogreen Tankless Water Heater

Water Efficiency

One of the primary benefits of this water heater is its water efficiency. Traditional water heaters constantly heat and reheat water, even when it’s not in use. In contrast, tankless water heaters only heat water when it’s needed. It takes less time to heat up water, and can save up to 20% of water usage – allowing you to do your part for our environment. It also means that you can save money on your water bills.

Endless Supply of Hot Water

Another benefit of the Siogreen Tankless Water Heater is that it provides an endless supply of hot water. Traditional water heaters have a limited amount of hot water available, which can be a problem for larger families or businesses with high hot water demand. With a tankless water heater, hot water is produced on demand, so you never have to worry about running out of hot water. This can be especially beneficial for homes with multiple bathrooms or for businesses with high hot water demand.

Space Saving Design

The Siogreen Tankless Water Heater has a space-saving design that can be a major benefit for homes or businesses with limited space. With the Siogreen tankless water heaters, you can install them in a variety of locations, including closets, attics, or even outside. This can be especially beneficial for businesses that need to maximize their space or for homes with limited storage space. Additionally, their models come in a sleek design with white and grey colour, so you have the flexibility to install it out in the open if you wish. A clean and simple design is not always common for a tankless water heater, so this is definitely a plus in my book.

How to Choose the Right Siogreen Tankless Water Heater


When choosing a Siogreen tankless water heater, it is important to consider the size of your household and your hot water usage. Siogreen offers a sizing guide on their website to help you determine the right water heater based on your needs. Consider the number of bathrooms and fixtures in your home, as well as the flow rate of each fixture. A larger household with higher hot water usage will require a larger tankless water heater.

Fuel Type

Siogreen offers both electric and gas-powered tankless water heaters. Electric tankless water heaters are more energy-efficient and easier to install, but they may not be able to keep up with high hot water demand. Gas-powered tankless water heaters are more powerful and can handle larger hot water demands, but they require more maintenance and installation can be more complicated.

Location and Climate

Consider the location of your tankless water heater and the climate in your area. If you live in a cold climate, you may need a more powerful tankless water heater to handle the demand for hot water during winter months. If your tankless water heater will be installed outdoors, it will need to be weather-resistant and protected from the elements.


Siogreen tankless water heaters are generally more expensive than traditional tank water heaters, but they can save you money in the long run with their energy efficiency and longer lifespan. Consider your budget and the long-term savings when choosing a Siogreen tankless water heater. Keep in mind that gas-powered tankless water heaters may have higher installation costs due to the need for proper venting. Overall, choosing the right Siogreen tankless water heater depends on your household’s hot water needs, fuel type preferences, location, and budget. Use Siogreen’s sizing guide and consider all of these factors to make the best decision for your home.

Installation and Maintenance

Installation Process

Installing a SioGreen tankless water heater is a relatively simple process. However, it is important to follow the instructions provided in the installation manual to ensure that the unit is installed correctly and safely. The manual provides detailed information, including diagrams, specifications, and step-by-step instructions for tankless water heater installation and basic operations. The following are some general steps to follow during the installation process:

  1. Turn off the water supply to the house.
  2. Disconnect the old water heater and remove it from its location.
  3. Install the mounting bracket for the new tankless water heater.
  4. Connect the water supply and the gas or electric supply to the new unit.
  5. Turn on the water supply and check for any leaks.
  6. Turn on the power supply to the unit and test it to make sure it is working properly.

It is recommended that you hire a professional plumber or electrician to install your tankless water heater, especially if you are not experienced in plumbing or electrical work.

Maintenance Tips

Proper maintenance of your SioGreen tankless water heater is important to ensure that it continues to function efficiently and effectively. The following are some tips to help you maintain your unit:

  • Regularly clean the water filter to prevent debris from clogging the unit.
