What to consider when buying a water softener?

Much of the UK is subject to hard water, meaning the water supply has a high calcium carbonate content. This can lead to limescale to build up in appliances and affect the quality of clothing once it’s been washed, as well as reducing the efficiency of boilers. If you’ve decided to combat the problem by purchasing a water softener system, you may be overwhelmed by the range of options available which can make choosing the right unit for your needs difficult.

There are three categories of water softener solutions, excluding filter systems which use reverse osmosis to purify water, which include:

Salt-based systems – Salt-based water softeners use sodium to replace hard water ions to soften the water. These units need a tank for resin beads as well as a salt chamber or brine tank which should be kept topped up to keep it working effectively. A process known as regeneration refreshes the resin beads which in turn soften the water. These systems are low-maintenance as they’re typically timer or metre-based. The units can be larger and need to be installed near a drain so that the salt tank waste can be drained off.

Salt-free systems – Salt-free units use nano-technology to change the atomic structure of the water in order to soften it, usually in moderately hard water areas. If limescale has already built up in the plumbing system of your home, this form of water softener is highly effective in removing this from the plumbing to make sure the situation doesn’t get any worse. The running costs of salt-free systems are usually lower, and they are easy to maintain, as well as there being no need for them to be installed near a drain. They’re also considered to be eco-friendlier, but they might not be as effective in removing the hardness of the water.

Electro-magnetic systems – Electro-magnetic systems are the smallest units available so they’re ideal for space saving, and they work by using magnetic wires around the water pipes to change the structure of the water molecules to soften the water. This type of system is ideal for low to medium hard water and is also environmentally-friendly. Electro-magnetic systems are easy to install and are low maintenance, as well as being cheap to run.

There are a few different factors to consider when buying a water softener, which are:

Salt – Most water softeners work through the use of salt to remove minerals in the water. Water softener salts usually come in either salt ‘cake’ form or in crystalline form. Some filters will be able to function with any form of salt, while others will specify the type of salt needed, so this should be checked beforehand, so you can choose the most practical option for you depending on the mineral content of the water in your local area.

Capacity – Larger tanks which have larger filters will typically last for a longer period of time without requiring any maintenance than smaller tanks. This impacts how much the unit will cost to run, not just for the device but also the filters it will use. 

Efficiency – Efficiency is key to any unit you decide to purchase for the best water softening effects. Some important factors are the size of the reservoir, the quantity of salt it can contain and therefore how long each supply will last before it needs to be topped up, as well as how long the filters will last before they need to be replaced.

Mineral-dense water can cause serious problems to a building’s plumbing and to water-based appliances, as well as causing the body to accumulate potentially harmful amounts of minerals. The following list of water softeners are some of the best on the market to suit a range of needs and water types.
