Industry myths about water softeners

A common misconception in the heating and hot water industry is that water softeners cannot be fitted alongside central heating systems.

More than 60% of the UK suffers from hard water.

This is caused by the water that feeds our homes and properties depositing calcium and magnesium that it has picked up when passing through chalk beds in the ground.

Once the calcium and magnesium is heated, it deposits itself as hard water scale. That’s why you get more scale in hot water than in cold.

This leads to scale and scum being experienced all around the home. Hard water also reduces the effectiveness of cleaning products and shampoos.


A water softener overcomes these issues by removing the calcium and magnesium on demand from the water as it flows through the unit. When the unit becomes full of calcium and magnesium, it then automatically cleanses itself with a weak solution of salt and water called brine. The previous collected calcium and magnesium, together with the brine are automatically sent to drain. At no time does the brine enter the water supply; dispelling the myth that soft water has salt in it!

The Myth - A water softener is difficult to install - A water softener is difficult to install

The Buster - If you can install a washing machine you can install a water softener. They all need a little plumbing work, a drain and some models need a power point too.

The Myth - I am not sure if i can have a water softener with my bolier? 

The Buster - Not one, but two British Standards (BS14743 & BS7953) state quite clearly that every hard water home in the UK regardless of the type of boiler it has installed can have a water softener. The industry agrees that as long as the primary side of the system is filled with hard water (by placing the softener onto bypass when filling) then there will be no issues at all. Leading boiler and chemical manufacturers like Worcester, Sentinel, Fernox, Kamco, Adey and Spirotech etc, all support this position.

The Myth - Water softeners make drinking water taste salty

The Buster -Inside a water softener unit, water passes through a container which houses thousands of tiny beads, which attract and retain the calcium and magnesium from the hard water. Every so often, these beads need cleaning. This is done automatically by the unit, which sends a weak solution made up of salt and water through the container to wash the beads clean. The unit then automatically flushes this dirty water down the drain, leaving the beads clean and ready to begin another cycle. So, salt doesn’t soften water itself, but instead it cleans the unit out.

This means that no salt enters the water supply, however it is possible that a tiny amount may be left over from the cleaning process.

The Myth - Water softener units take up large amounts of space in a home 

The Buster - Manufacturers of water softeners have worked hard to reduce the overall size of the units, without impacting on their efficiency. Just like boilers have become more compact and neater, so have water softener units. The water softeners also free up space that may previously have been taken up with copious amounts of cleaning products. This reduction in cleaning products also makes water softeners a better environmental solution for your customers.

The Myth - You lose water pressure through a water softener 

The Buster - Today’s modern water softeners all have high flow internal distribution systems to give optimum flow at all times.
