Twin Tank vs. Cabinet Style Softeners


If you live anywhere in Nebraska and have hard water, you are likely to have considered a water softener. There is a wide selection of systems available, but how do you choose between a twin tank or a cabinet style device? Both of these systems have their own particular features, so you need to have an understanding of the benefits of each so you can make an informed choice.Twin Tank vs. Cabinet Style Softeners

The Difference Between Twin Tank and Cabinet Style Systems

A cabinet system tends to offer a compact and space saving option, which has a resin tank and brine tank within the one cabinet. These systems tend to offer “on demand” softening that monitors how much water is being used and regenerate as needed. If your untreated water contains high levels of iron and hardness, this can reduce its effectiveness. Modern cabinet style systems tend to require less salt and water; they also may include features to allow you to manage your consumption and maintenance more effectively via computer systems or remote Smartphone apps.

As the name suggests, a twin tank system features two resin tanks. This allows for one tank to be regenerating while the other tank is in use. Although this tends to require more floor space and can be more costly initially, if you have a larger family or use water throughout the whole day, it could be the best choice for your home.

Why Choose a Twin Tank Softener?

When cost is likely to be a major consideration, you may wonder if it is worth spending more on purchasing a twin tank softener. The main advantage of a twin tank system is that it can continually produce softened water. Once one tank has reached capacity and requires regeneration, the other tank can take over.

Many homeowners think that if they have limited space, they are restricted to a cabinet style device, but this is not necessarily the case. Depending upon the brand, a twin tank unit may not be larger than a single tank system. In some cases, a twin tank may actually be smaller than a single tank system.

A twin tank softener may be the best choice for your home if you have very hard water. If your water hardness levels are 40 grains per gallon or more, a single tank system may not be able to soften sufficient water to meet your needs. In this scenario, a single tank system may need to more frequently regenerate, wasting both energy and water.

Many homeowners find that the unit needs to be disconnected from the water supply when it is recharging, so the cycle needs to be timed to occur during the night. Unfortunately, this can mean that the unit will not produce sufficient soft water for use throughout the day.

You may also need to consider other contaminants in your water supply. For example, if your water contains iron, these particles can add to the water hardness level, increasing the demand on your softener. With a twin tank unit, the regeneration cycle can be set for anytime, ensuring that you have a steady supply of softened water.
