Is Kinetico the best brand?

Kinetico is a US born brand that sells premier ater softener models. When researching online, you’ll see that Kinetico water softeners don’t come cheap, with some of the most expensive price tags for home systems. And yet, at a greater price - they may not necessarily offer superior specifications. That's why with any brand - it important to compare specific models and their full specifications before buying.

Previous Kinetico models

Kinetico’s main range is the Premier Series – with the Premier Compact standing as the most popular product. Prior to the Premier series, there have been several models that are now discontinued, including the Kinetico 2020c. The 2020c was a popular model and has now been replaced by newer Premier series options.

Review Break Down

The Premier Compactis Kinetico's most sold system, designed for family homes.

When reviewing and comparing this system it is important to check and compare key specification points.

Who is it Designed for?

The Premier Compact is aimed at family homes, often with up to around three bathrooms depending on water usage, pressure and plumbing setup.

Key specification points to compare

Flow rate and pressure range
Salt and water usage per regeneration
Warranty and aftercare route
Water hardness capacity
HE or HF model suitability
Installation route and total fitted cost
Alternative options.

💧

Flow Rate and pressure The flow rate and pressure are important because they are dependent on one another. Therefore, as the max flow rate is reached, pressure can decrease. Why is this important? Because a low flow rate can result in pressure drops when homes demand more water at once. e.g. two people using the same tap at once. The Premier compact has a flow rate of 51L/min but a pressure range of only 1- 6 bar.

🧂

Salt Usage Water softeners require salt to work - the amount of salt per regeneration is important because it can determine your running costs. It is also important to check the salt efficiency of the system. This Kinetico model uses 340g of salt per regen.

⏱️

Regeneration time This model regenrates in only 11 mins.

⚙️

Type of System The type of system matters. Why? Because electric vs non-electric can influence running costs, and single vs twin tank designs can directly affects your supply of soft water. The Permier series are non-electric, twin tank and block Salt systems.

🛡️

Premier Compact Warranty The warranty of your system is important. Longer warranties tend to represent better quality systems built to last. It can also tell you about aftercare. This model has a 2-year labour warranty and a 10-year warranty on parts.

🌊

Water Used Similarly to salt usage, water usage is important because it can tell you about the efficiency of a model. This system uses 20.5 litres. .

Dimensions and Design

The Kinetico Premier Compact is a block salt, twin tank system, the size of this system is in the name - being "compact" it fits under-sink with dimensions of approx. 498mm x 219mm x 468mm.

The Kinetico Premier Compact Price

The Kinetico Premier Compact is not on the cheap side, at £1695 - £1795 without installation, this system is more expensive than other alternatives on the market.

Installation

A water softener installation is usually straightforward for a trained plumber and may take a few hours depending on pipework. It is normally installed near the incoming mains water supply and requires drainage access for regeneration.

Maintenance and block salt

The main ongoing maintenance cost is block salt. Salt is required for ion exchange regeneration, so “salt-free” systems are not true water softeners. Salt use depends on household size, water hardness and usage.

The Premier Compact uses standard block salt - so when it comes to Kinetico water softener block salt - it really doesn't matter which brand you buy. Harvey Block salt can be cheaper to purchase with delivery across all of the UK.

Kinetico Premier Compact Alternative: the Harvey TwinTec S4

For this review purpose, we are going to compare the Premier Compact to the TwinTec S4 - we will compare all specification points so you can compare technical aspects to value for money.

Specification	Kinetico Premier Compact	Harvey TwinTec S4
System type	Twin tank, non-electric	Twin tank, non-electric
Max flow rate	Approx. 51L/min	Approx. 56L/min
Pressure range	Approx. 1–6 bar	Approx. 1–10 bar
Salt per regeneration	Approx. 340g	Approx. 300g
Water per regeneration	Approx. 20.5L	Approx. 17–20.5L depending on source/spec route
Regeneration time	Approx. 11 minutes	Approx. 11 minutes
Warranty	10 years parts / 2 labour depending on route	10 years parts / 2 labour depending on route

Premier Compact Vs Harvey TwinTec

Flow rate and pressure range: the TwinTec offers a higher flow rate of 56L/min.
Salt and water usage per regeneration: the Harvey model uses 300g and 17L vs 340g and 20.5L used by the Kinetico model. Also the TwinTec has a salt efficiency of 50% Vs only 35% for the Premier Compact.
Pressure differences: the Premier Compact has a lower pressure range, meaning you may be more likely to see pressure drops in homes where water demand is higher. The pressure range is 1-6Bar Vs 1-10 for the Harvey branded model.
Warranty and aftercare route: Both offer a 2-year labour and 10-year parts warranty with great aftercare.
Water hardness capacity: Both Kinetico & Harvey softeners have a high hardness gearing to softener very hard water.
HE or HF model suitability: the Premier Compact comes in both HE and HF versions– which you may need to specify in some cases. The TwinTec is one model suitable for all boiler types and systems.
Installation route and total fitted cost: This Kinetico model is generally only sold via an expensive dealer network - meaning you may have to invest in a full installation package.

Water hardness and model type

The Premier Compact may be available in different versions depending on pressure and plumbing requirements. If you have a combi boiler or higher-flow system, make sure the chosen model is suitable before buying. If you have a combi boiler system, you need a HF system, standing for high flow. If you have a low-pressure gravity-fed system (water tank in the loft), your home requires a HE system, standing for high efficiency.

Price Comparison

The biggest issue homeowners face when looking for a Kinetico system is the price. The price of a system without installation is £1695 - 1795. We think the Premier Compact is a great model, but as you can see from comparing the model comparisons - the Premier Compact is not a superior model, infact Harvey actually present a better specification. The differentces between the systems are marginal but at £500 cheaper, Harvey is in our opnion better value for money.

Is the Kinetico Premier Compact worth it?

The Kinetico Premier Compact is a premium water softener and may be a good choice for many homes. We have sold both the Premier Compact, the Kinetico Premier range and the Harvey TwinTec range and found Harvey to be better value for money, with an almost identical specification. We don't recommend spending extra - unless you specifically want the Kinetico brand.

Pricing note: pricing can vary depending on the retailer.
