Buying The Right Water Softener

The primary purpose of water softeners is to remove the calcium and magnesium, replacing them in the mineral tank with sodium through an ion exchange process.

Water softeners also affect the lifespan of your water heater, and you are guaranteed that film is not left by the soap at any point. When you know the benefits of the water softener, you will recognize why you need to buy one for your tankless heater. Some of the benefits include:

Why Does Your Tankless Water Heater Need A Water Softener?

The first sign of hard water running in your home is spotty dishes and glassware. You will easily be able to spot the film of soap scum that develops on the bathtub, shower walls, and shower doors. But thankfully, removing the film is an easy process. The hard water might also affect your cleaning agents and make your laundry look pretty dingy. Your skin is also likely to have a scratchy and rough feeling, especially in places of low humidity in the winter months.

Now that you’ve gotten here, you should know why your water heater needs to have a water softener. Go through the details of these five water softeners, and you can even gain more clarity by going through the guide for buying the right softener.

1. Save money: The level of calcium in hard water is pretty high and it is also a poor conductor of heat. So, the water heater uses extra energy to ensure you get the right temperature when scale builds up in your hard water from the mineral. This causes your energy bill to be higher as the minerals in the water make your water heater perform more work to get the necessary amount of heat. The water softener prevents build-up and this boosts the efficiency of your water heater’s performance.

2. Longer plumbing and low risk of clogs: Scale build-up is developed in the water heater, and plumbing also aids its development. This causes the diameter of the pipe to become smaller while the tubes will not last as long. The water softener also works to clear any build-up as the risk for messy clogs is reduced. So, you will not spend as much time in the shower, sink, cleaning pipes, or scrubbing the bathroom. 

3. Softer skin and cleaner laundry: Hard water makes it difficult for soap to lather, so you will need to wash with more soap than necessary so you can get the amount of cleanliness you desire. When you use an efficient water softener, the clothes you wash will be soft and bright. The soap will lather easily so they will be much cleaner. Your skin and hair will also benefit greatly from the water softener as well. Your hair won’t look frizzy and dry, and your skin won’t look dull. They’ll both look healthy and bright when you use water without calcium and magnesium contained in them.

What to look for when buying tankless water heater

  • The water softening system’s price is mainly reliant on the brand, capacity of the system, the features it possesses, the materials, as well as the type of water softener. 
  • You can choose to use a salt-based softening system or a saltless water softener. These salt-based softeners are bigger, so you can buy alternate models like magnetic, electric, and softening systems that are free from chemicals. 
  • You can also get a system that has a user-friendly feature like a filtration system so that the water will automatically be cleaned to help it taste better.
  • To ensure the longevity of your water heaters, ensure that the water softeners are made using materials of high quality. It’s best to get one with at least a one-year limited warranty. 

If you choose to get a salt-based softener, then you should check for the resin capacity. You also need to ascertain how much water you use depending on the number of people using it. A larger capacity means that there will be a low frequency of the softener regenerating. There is a wide variation in the grain capacity and this capacity is linked to the brine tank.

Another important thing you should consider when choosing which water softener to buy is space. Many houses go with the middle size of the softener. This means having an iron tank and brine tank with a 2-piece item is enough. You need a big capacity with these systems because of the brine tank. You can ask for the dimensions of the water softener from the manufacturer, and even get full details about the product online.

On a Final Note

  • Ensure you have all the information you need before you start shopping, Water softeners are available in many different varieties and brands. Every brand works to get rid of calcium and magnesium, replacing them with sodium ions.
  • Look at the salt-free water softeners. You can also ask some professionals because water softeners come in two variants: electromagnetic and catalytic, which work to prevent the build-up of limescale.
