The Importance of a Water Softener for Tankless Water Heaters
As a homeowner who recently made the switch to a tankless water heater, I can attest to the many benefits it offers. From energy efficiency to endless hot water supply, it has been a game changer. However, one thing that often gets overlooked is the need for a water softener for tankless water heaters.
Tankless water heaters work by rapidly heating water as it flows through the unit, rather than storing hot water like traditional tank heaters. This means that any minerals and sediments in your water supply can quickly build up and cause damage to the heating elements and other components of your tankless water heater. This can lead to reduced efficiency, frequent breakdowns, and costly repairs.
Installing a water softener helps prevent these issues by removing minerals like calcium and magnesium from your water supply. These minerals are responsible for creating hard water, which not only causes damage to your appliances but also leaves behind stubborn deposits on dishes, clothes, and surfaces.
In addition to protecting your tankless water heater, a water softener also has numerous benefits for you and your family. Softened water is gentler on skin and hair, prevents soap scum buildup in showers and sinks, and extends
My Buying Guide on ‘Best Water Softener for Tankless Water Heaters’
I have been using a tankless water heater for quite some time now and one issue that I faced was hard water. Hard water can cause a lot of problems for tankless water heaters, such as scaling, reduced efficiency, and shortened lifespan. After doing some research and trying out different options, I have found the best water softener for tankless water heaters. In this buying guide, I will share my experience and knowledge to help you make an informed decision.
Understanding Tankless Water Heaters
Before we dive into the different water softeners available, it is important to understand how tankless water heaters work. Unlike traditional storage tank water heaters, tankless water heaters heat the water as it passes through a heat exchanger. This means that there is no standing hot water in the tank and the heating element is constantly in contact with the incoming hard water.
The Importance of Water Softeners
Hard water contains minerals such as calcium and magnesium which can cause scaling in pipes and appliances. In tankless water heaters, this scaling can build up on the heating element, reducing its efficiency and eventually leading to damage. Using a water softener helps to remove these minerals from the water before it enters your tankless heater.
Factors to Consider
When looking for a water softener for your tankless heater, there are a few factors that you should consider:
Flow Rate
Since tankless heaters have high flow rates compared to traditional storage tanks, it is important to choose a softener that can keep up with this demand. Look for softeners with higher flow rates (measured in gallons per minute) to ensure that your heater receives enough softened water.
Salt-Based vs Salt-Free
There are two main types of water softeners – salt-based and salt-free. Salt-based softeners use ion exchange technology to remove minerals from the water while salt-free softeners use different methods such as template-assisted crystallization or magnetic fields. Salt-based softeners tend to be more effective but require periodic maintenance whereas salt-free ones are low maintenance but may not be as effective against very hard water.
Size and Installation
Make sure that you choose a softener that is suitable for your household size and can fit in your available space. Also consider if you will be installing it yourself or if you need professional installation.
Top Picks
Based on my experience and research, these are my top picks for the best water softeners for tankless heaters:
1) Fleck 5600SXT 48,000 Grain Water Softener: This salt-based system has a high flow rate of 12 gallons per minute making it suitable for larger households. It also comes with an easy-to-use digital control head.
2) Aquasana Whole House Salt-Free Water Softener: This salt-free system uses template-assisted crystallization technology and has a high flow rate of 7 gallons per minute. It also has an easy-to-install design.
3) Eddy Electronic Water Descaler: This salt-free system uses electromagnetic waves to prevent scale build-up instead of removing minerals from the water. It has no flow rate limitations making it suitable for all household sizes.
In Conclusion
Having dealt with hard water issues myself, I highly recommend investing in a good quality water softener for your tankless heater. Consider factors such as flow rate, type of softener, size, and installation before making your decision. With my top picks as a reference guide, I hope you are able to find the best option for your household needs.
