Our water softener

The Harvey water softener

First, the basics

A Harvey water softener is a device about the size of a computer tower. It gets plumbed in to your house, usually underneath the kitchen sink, and it takes the water as it comes into the house and runs it through a pair of softening tanks, which remove the minerals from the water that cause limescale and soap scum.

Every so often, the machine flushes the minerals from the tanks by rinsing them through with salt water, which is why it needs to be kept topped up with blocks of salt. Aside from that, you don’t need to do anything to keep it running.

We wouldn’t expect you to just take our word for it …

Map: The south and east of England are very likely to have water harder than 300ppm (roughly equal to 300mg/l as CaCO3)

In a very hard water area (over 300mg/l as CaCO3) using a water softener device could reduce maintenance and water heating costs by up to £50 per year, or £580 over the lifetime of a boiler.

This is calculated for a 4-person household with a gas-fired combi condensing boiler and includes both energy savings and maintenance costs for descaling the boiler 3 times, estimated at £169 per procedure. The household pays 4.21p/kWh for gas. Figures valid for 2014.

Using a pair of compact cylinders seemed like such a simple idea, I couldn’t see why no-one else was doing it. The obvious thing was that we could make the softener much smaller. But what surprised us was how much simpler it became to get really great flow rates and efficiency. Harvey Bowden - Chairman & Inventor

How our water softener works

Cutaway diagram of the Harvey water softener

At the heart of a water softener is its ion-exchange resin. The resin consists of microscopic beads, and as the hard water passes through them, they trap the magnesium and calcium ions that are in it, so the water comes out totally soft. This is a fairly simple process that’s been in use for over ninety years.

The complexity of modern softeners comes in when the resin needs regenerating. This happens when the resin has trapped all the hardness minerals it can, and needs to be flushed through with salt water. The timing of the regeneration is crucial: too soon, and you waste water and salt; too late, and you risk hard water getting into your system.

Our design uses a water meter to judge when to regenerate. We use a displacement meter - the most accurate meter there is, and the one used by water companies to calculate your water bill. It avoids a common problem: most types of meter can’t measure the flow of water if it’s very slow, which happens whenever a loft tank or toilet cistern is filling up.

"The showers and bathroom stay clean and this makes a huge difference"

The King family, Hampshire

Never a drop wasted

This is our revolutionary displacement meter. It measures precisely how much water has been softened, even when the water is hardly flowing at all, so that the softener regenerates at exactly the right time. Too soon, and you’d be wasting water; too late, and hard water would creep into the system. That’s why our softener gets it just right.

Water softener guides

Water Softener Installation

A water softener is usually fitted under the kitchen sink, but it can be fitted anywhere that it’s convenient for you. Common locations include:

  • the garage
  • the loft
  • on an outside wall
  • A Harvey water softener, installed in a garage
  • A Harvey water softener, installed in the cupboard under the kitchen sink
  • A Harvey water softener, installed outside

Our installers are all trained and experienced in fitting water softeners in all of these situations. Installation is a fairly simple process - a little more complex than a washing machine, but much simpler than having a new boiler fitted. It usually takes no more than half a day, though our plumbers never rush - we make sure they have time to do a good, robust and tidy job.

Topping up a Harvey water softener with block salt

Block salt

  • No heavy bags to struggle with
  • A year’s supply takes up less space than a set of golf clubs on a trolley
  • We say the average UK households requires one block of salt per person per month

When the salt blocks near the red line in your softener, it’s time to re-order.

The Harvey water softener installed in the cupboard under the kitchen sink

Fits under the kitchen sink

The best place for a softener to be fitted is usually under the kitchen sink.

That’s why we designed our softener to fit there.

It’s made possible by the innovative arrangement of the two compact cylinders and our custom-made valve - and our reversible fittings mean that the unit can always go in the most convenient space.

Dimensions: 490mm x 460mm x 212mm

"The service that we have received has been exceptional"

"Everything Harvey's said would happen has happened. We like to support British companies and felt reassured by Harvey's British design and hand-built quality. I fail to see how you could improve on it!"
