Features and Highlights: What Makes The SioGreen IR288 Better?

You are probably thinking, at this stage, what is it really that makes this electric tankless heater different or better than its competitors. With this section, you’ll familiarize all the outstanding features and highlights that will push you to decide.

No-Risk of Internal Components Corrosion

If you have already owned a tankless water heater, you may be familiar with the problem of corrosion to its components, caused by the water that flows through the system. One of the main selling points of this product is that corrosion is no longer an issue. Indeed, in contrast to other competitors, the SioGreen 288 uses infrared tubes made of quartz that can generate heat without having to come into direct contact with metal. To put it simply, this means that the internal environment functions in a way that prevents corrosion from occurring, saving you from the headache of having to maintain the heating system regularly.

No Need To Worry About Limescale Deposits

Homeowners who have switched to tankless water heaters often find themselves frustrated by the mineral and deposit buildup that can occur over time, reducing heating performance. This is especially true in areas with hard water problems. The accumulation of minerals and deposits not only affects heating performance, but also allows bacteria and algae to thrive, which can adversely affect the quality and safety of your water.The good news is that SioGreen IR288 prevents these problems by design. The excellent material and thoughtful design don’t allow water sitting, eliminating the accumulation of any organism and the development of algae and bacteria. That results in safe water and a high-performing heating system at all times.

Maintenance? Not A Problem Anymore!

Regular maintenance of your water heater is essential, and its importance cannot be overemphasized. This might mean hours and money spent on complex maintenance operations that will keep your water heater functioning for longer. However, this is not the case with the SioGreen IR288. This model is extremely easy to maintain because it doesn’t use a heating element, which eliminates the need to flush it constantly to keep it working at its optimal capacity. If you are looking to save both money and time, this may be the perfect heater for you.

It Uses The Innovative Far – Infrared Technology

Remember when we mentioned the quartz tube, that doesn’t need to be in contact with the water to be heated? Well, the benefits of this incredible material are much more than that. Indeed, this water heater, with its carbon coating combined with the use of innovative technology, is designed to amplify the energy produced by the tube. This means that as long as your heater is turned on, it will use the same amount of energy, even with an increased flow rate, resulting in lower utility bills and a happier homeowner.

Better Control with the Automatic and Manual Power Functions

This electric water heater is easy to control: thanks to the automatic and manual control modes, you can control it effortlessly and efficiently. The automatic mode is handy as it comes equipped with modulating technology to estimate the variation between the desired temperature and the outdoor temperature of the moment. That is to predict how much power will be needed to heat the water according to your needs. The great thing about this mode is that it adjusts automatically to any changes and you don’t have to intervene. On the other hand, the manual mode allows you to hold the power button and adjust the current based on your needs. Most users tend to stick with the automatic mode, as it is pretty reliable and easier to use.This electric water heater is easy enough for anyone too operate

Adjust the Temperature Without Issues With the Dual-Mode Temperature Control

The Sio Green IR288 is designed to automatically adjust the heating temperature, as well as being manually adjustable. When choosing the automatic mode, you simply press the button and let the integrated software take care of everything. In manual mode, you have to raise the temperature manually by choosing a level from 1-8, by turning the water flow regulator. This might not seem important now, but think about how important it is to have a heater that meets your hot water needs exactly. With the IR288, you can dictate how hot or cold you want your water; while also checking easily on the temperature through the large LCD screen- which is extremely handy.
