Culligan is a veteran in the water treatment industry and no doubt one of the top brands that provide the most reliable water solutions for residential and commercial use as well as industrial applications.

The High Efficiency series covers Culligan’s entry-level dual-tank water softeners for home use and although they are considered as entry-level, the models in this series are some of the most advanced water softeners in the market today.

As the name suggests, these models offer the highest efficiency compared to all the other Culligan softeners when it comes to salt and water usage. They are specifically tailored to cut the running costs down to a bare minimum.

The water softeners within this series are divided into two categories, the HE 1-inch systems, and the HE 1.25-inch systems. They are very identical systems but differentiated by the size of the control valve they come with.

Softening Capability and Capacity

The Culligan HE 1-inch Water Softeners

The HE 1-inch is the baseline category and it consists of four sizes ranging from 9 to 14 inches in terms of media tank diameter. These models come in different configurations but they are all equipped with Culligan’s 1-inch reinforced thermoplastic control valve and work with normal 1-inch pipes hence the name.

With regards to softening ability, they can remove water hardness levels from a range of 75 to 99 GPG using the effective Culligan’s CULLEX ion exchange resin.

This high hardness removal rating means they can reliably deal with medium and high levels of water hardness. The 9-inch model is the most basic unit offering a maximum water hardness removal level of 75 GPG.

These models have also the capacity to remove up to 5 ppm of ferrous iron and can deliver 9 to 10.6 GPM flow rate at 15 psi which is a fairly high range that can ensure a steady flow on all water outlets in the house.

Their total softening capacity ranges from approximately 30,000 to 90,000 grains with the 9-inch model having the lowest capacity at, 31,736 grains while the 14-inch model holds the largest capacity at 88,549 grains. Therefore, depending on your particular needs, these models can work well for small to large homes.

The Culligan HE 1.25-inch Water Softeners

The HE 1.25-inch water softeners are only one step above Culligan’s standard HE 1-inch models as they feature a 1.25-inch reinforced thermoplastic control valve and can accept pipes of up to 1.25-inches in diameter (hence the name).

This category equally consists of four different sizes ranging from 10 to 16-inches in terms of media tank diameter. All four models can handle hardness levels of up to 99 GPG and are also able to clear ferrous iron from the water to a maximum level of 5 ppm. So, they can effectively deal with water that has higher hardness levels and medium iron content.

As for the water flow, the HE 1.25-inch water softeners are amongst the few models in the market that offer the fastest water flow rate. They can deliver 14 to 22 gallons of water per minute at 15 psi making them perfect for use in larger households that have high water demands.

Besides the fast flow rate, these HE 1.25-inch softeners provide a pretty large exchange capacity ranging from 45,000 to 128, 000 grains. The lowest is the 10-inch model with 45,831-grain capacity and the highest is the 16-inch version with a maximum of 128,106 grains. With this range, the HE 1.25-inch models are more ideal for medium to larger households.

Regeneration Technology and Control System

The models in both the HE 1-inch and HE 1.25-inch series utilize the same regeneration technology and have a similar control system that comes packed with most of Culligan’s advanced features (modes of operation) that ensure smooth operation and the high efficiency associated with these HE water softeners.

They utilize an effective meter-based downflow regeneration process where the controller monitors the quantity of water flowing through the system upon which it determines and sets the point of regeneration based on the water hardness level and the capacity of the resin bed.

This operation is initiated by selecting a water meter mode on the control panel and regeneration is triggered immediately the setpoint is reached.

All the HE series water softeners are as well equipped with Culligan’s patented Aqua-Sensor technology inbuilt within the control system.

This smart technology utilizes a conductivity probe that senses when the hardness minerals pass through the resin bed and automatically adjusts the system if there are any changes in your home’s water conditions.

This way, the system is able to only regenerate when needed. It’s a great feature that provides the most efficient mode of regeneration and very useful in conditions where there’s high variation in the influent water hardness throughout the year.

Furthermore, it can determine if the brine solution has been rinsed from the resin bed especially during the Slow Rinse cycle and trigger the control to switch to fast rinse.

As such, this Culligan’s patented technology can equally help minimize water usage as it optimizes the amount of water needed to totally rinse out the resin bed.

The HE series water softeners also provide a predicted mode which is another advanced feature that helps enhance their efficiency. In this mode, the control compares your average daily usage with the remaining reserve capacity and then effectively determines the optimum regeneration point to facilitate smooth operation.

Customization is possible too with these Culligan’s softeners. They have a Dial-A-Softness feature which is a manual adjustment that’s built into their control valves. This feature allows you to adjust the water softness to your preference including completely bypassing the softener.

To simplify the maintenance of their softeners, Culligan has incorporated a smart brine tank probe in each model of the HE series.

This device monitors the conditions inside the brine tank and can tell you the duration your softening salt will last so that you know exactly when to add more to the brine tank. It can as well tell you when the brine tank is overfilling.

Some of the other features that stand out in these Culligan High Efficiency water softeners are the pre-rinse mode for pre-rinsing the resin bed and the Culligan ConnectTM interface which is a mobile app that allows you to monitor and even control the softener using your phone.

You can get low salt alerts, initiate regeneration or put the system in bypass mode from anywhere just through the app which is pretty convenient.

Above all, one amazing thing you are going to like about these models is that you can completely install them outdoors. They employ high-impact Quadra-Hull tanks which can withstand corrosion, rust and even UV rays. As long as you provide good shade to protect the electrical part, they are completely safe outdoors.

Overall, for the highest efficiency as well as smart technology, this HE series takes the upper hand. The HE 1-inch models are a perfect fit if you want a much efficient but affordable Culligan water softener while the HE 1.25-inch models are ideal for those who want the same efficiency but a faster flow rate and softening capacity.
