Who is Kinetico?

The Kinetico brand has been around a for sometime. Kinetico originated in the USA and also sell their systems into Europe through a dealership and trade model. However, they are not the market leaders in the UK. Harvey Water Softeners are Kinetico's biggest competitors - originating and dominating in London and the UK.

But is Kinetico the better brand? Both Kinetico and Harvey offer machines with very similar specifications and service plans. That's why, before paying a higher price it is always important to compare different systems and their individual specification.

What are the different types of water softener?

Kinetico don’t sell their products directly to consumers, they do so through a distribution model and exclusive retailers. This sales channel is generally split by region or through online and e-commerce. There are several different models of Kinetico water softener – some systems have now been discontinued and replaced with a newer models.

When choosing a water softener, regardless of model, it is important to make sure you get the right system for your home. And this depends on how large the home is and how many bathrooms you have. Any home with more than 1 bathroom, is likely to require a twin tank system. Twin tank and non-electric softeners are the best to buy under most circumstances.

Why? A twin tank system generally has a higher flow rate, meaning more soft water and less of a risk of pressure drops in the home. A non-electric system is the most efficient you can get. It not only removes the addition of electricity and these added running costs, but it also makes the system easier to install and more manageable in the long run.

When buying a non-electric system you’ll find:

  • Automatic systems — they are less expensive to run and maintain. There’s also no risk of electrical components becoming damaged and becoming fused.
  • Generally Twin tank systems — Systems with two tanks are able to provide you with continuous soft water.
  • High hardness gearings — These softeners have a high hardness rating.
  • Metered regeneration — they use a meter to determine when it is ideal to regenerate, preventing water wastage.

Harvey & Kinetico models 

Kinetico’s previous range included the Kinetico 2020c and the Kinetico Kube. Their newer and premium range is called the Premier series, which includes: The Kinetico Premier Compact and Kinetico Premier Plus

Kinetico Premier Compact Alternatives

The Kinetico Premier Compact is a popular Kinetico water softener. It is designed for the family home of up to 3 bathrooms. A cheaper alternative to this system, with a better specification - is the Harvey TwinTec S4. See below a comparison in specification:

The Kinetico Premier Plus & Alternatives

The Kinetico Premier Plus is a system designed for homes with 4 bathrooms - previously known as the Premier Maxi. The Premier plus has a max flow rate of 56L/min - which is actually the same as the smaller Harvey TwinTec S4. That's why we recommend purchasing the Harvey XL1 or XL2 system, if your home has 5 or more bathrooms. The flow rate of these larger water softeners is 80L/min (Vs 56L/min), meaning they are better suited to cater for larger homes and families with higher water demands.

Water Softener Installation

The installation is actually relatively simple process for any trained plumber. It is similar to fitting a washing machine and is easier than a boiler replacement. Any plumber should be able to install the system in 2-3 hours. The time taken will depend on where you are having the softener fitted and your pipe work.  

If you don’t have a plumber, you could try an online search, ask neighbours, family or friends and even websites such as Checkatrade.

How Much Does it Cost to Maintain a Water Softener?

Non -electric water softeners only need salt to run. That means they do not require electricity and so automatically save money on running costs. The only maintenance cost is to replace the block salt, in order for the system to work.

When researching into maintenance costs, it is important to compare: salt efficiency, water usage, energy usage, salt usage and regeneration time. The Harvey TwinTec S4 has the highest flow rate, lowest salt usage and water usage of any standard family home twin tank water softener. 

Kinetico Water Softener Block Salt

Kinetico premier compact water softener review


Block salt is required at all times for a water softener to work. If you are looking for a “salt free” system – the truth is, these products are not water softeners. They are water conditioners and they are not able to remove hard minerals from water.

Salt is needed to remove the hard water minerals from your water, through a brine solution. It is required at all times for the system to work.

The average usage of salt in a standard family home is 1 block per person per month. The blocks of salt can cost £6.50 - £8 per pack of 2 blocks. 

Harvey & Kinetico machines use standard block salt which is usually sourced sourced from Harvey Water Softener themselves.

Kinetico Water Softener Warranty

Generally any single tank system will only come with a 12-24 month warranty. However, products such as the Harvey TwinTec S4 and Premier Compact, come with a 10 year warranty.

Is a Kinetico Water Softener Worth the Cost?
