Factors to Consider When Purchasing the Best Electronic Water Descaler

1. Installation

Most electronic water descalers are easy to install. However, it is understandable that sometimes, non-mechanical and non-techie folks can still be challenged with the process. You have to ensure that you can complete the installation yourself if you buy a water descaler to save installation costs.

Buy an electronic water descaler system where the instructions are simple, which you can follow and understand even without any prior or background knowledge in installing such systems. It would be best if you chose a brand that can offer support and extra instructions as needed.

2. Available area

Dual tank, salt-based, and even some salt-free water descalers may require a lot of space to occupy. Thus, you need to measure the dimension of the area where the electronic water descaler will be installed and compare the dimensions to the manufacturer’s installation specifications to be sure about the space.

Most of the salt-free descalers are smaller than salt-based electronic models. Additionally, you can install them directly on the water system and hang them down one or two feet, depending on the brand.

Magnetic water softeners occupy the least amount of space, and you can install them directly without cutting into your plumbing. You can install these small water descalers directly on the pipe without interfering with your floor space. These units are the ideal option for smaller houses since they save on space.

3. Ion exchange capacity

When people mention buildup water descalers, they normally refer to regular salt-based softening that depends on an ion exchange process to replace hard minerals (magnesium and calcium) in the water with sodium or potassium ions. If you have issues with extra salt in your meals, you need to go for a salt-free water softener.

Generally, the ion exchange process is usually considered as the industry standard and is still the preferred option for many homeowners because of their unique performance. Nonetheless, salt-free water softeners are becoming common with increasing effectiveness.

4. The capacity of the electronic water descaler

Water softness or hardness is commonly measured using grains per gallon (gpg), where one is equal to a solution of 0.002 ounces of calcium carbonate and one gallon of water. Water with 0 to 3 gpg is considered soft water, and 3.5 to 7 gpg is moderate water, while water with over 7.5 gpg is usually considered hard water.

An electronic water descaler can measure grains for each week that the unit can handle before replenishing. Small water softeners come with weekly grain capacities from 16,000-32,000, while large water softeners have grain capacities from 40,000-64,000.

Remember that the harder your water is, the more grains your electronic water descaler system will handle. A 54,000-grain system would function differently and better with 3-gpg water running through it than if it had –gpg water to manage.

5. Bypass valve

Valves control the flow of water through a pipe, opening or closing it when necessary. Conversely, bypass valves also function in the same way as regular valves; however, their purpose, when used with an electronic water descaler, is to change the flow of water directed away from the system. This function allows you to use the system’s hard water running into the home.

This feature may seem useless if you have just bought a water descaler, but a bypass valve can save you time and money by preventing your electronic water descaler from using excess energy and salt to soften the water used for washing the deck and watering the lawn.

Thus, you can use the bypass valve to change the direction of the water flow around the water descaler and back into your pipes. Once your flow is complete, close the bypass valve and return water flow through your electronic descaler. 

6. Water descaler regeneration methods

Metered (demand-initiated)- This method is what digital systems use to trigger their regen process based on earlier water output. This regeneration is one of the environmental and cost-friendly methods since no more water and salt is being used than necessary. 

Manual– This method might be inconvenient and so only popular with portable models. Under this method, you have to add up salt directly into the system reservoir and give it time to move the magnesium and calcium stick to the resin beads.

Timed- This timer-based regeneration method allows you to set a particular regeneration time. Then the descaler system will backwash, recharge then rinse at certain time intervals, using the same amount of water and salt all the time irrespective of your prior water consumption. So, if you use a large amount of water than usual, you might run out of soft water prematurely. Using less water means a lot of salt and water is wasted.

7. The cost of the electronic water descaler

The cost of an electronic water descaler depends on its size, type, brand, and other additional features. You are bound to spend anywhere between a few hundred dollars to a few thousand dollars for a normal ion exchange system. Water conditioners are relatively cheaper, but it is also good to have a budget before shopping.

When you consider the price, also remember to take into account expenses involved in installation and operation. Additionally, ensure the electronic water descaler can pay for itself in the long run; even after fifteen years, your home appliances and pipe should still be in good condition.

8. Warranty and customer support

Purchasing a product online gives you different products to choose from and at the best prices. Nonetheless, it would be best to consider the warranties, whether you want to buy the product online or in some stores. Some companies selling these descalers provide separate warranties for different system components, while others offer after-sale services. Furthermore, some companies offer a money-back guarantee after you return the product in good condition.

Think about the customer support services that the company is offering. The item you want to buy should have great and active customer support in anything, preferably 24/7 support.
