Harvey Water Softeners

Introducing the NEW Harvey Minimax Innova. 

This is the next generation in water softeners with its improved design, eco-features and robust testing.  The Harvey Minimax Innova was launched in December 2020 and is the latest generation in water softening. Its advanced twin-cylinder technology is extremely efficient and means you will have softened water 24 hours a day, 7 days a week. It conveniently runs on the latest curved block salt, which is easier to store, handle and load compared to standard block salt. It's the most compact block salt softener on the market and fits under your kitchen sink.

Easy to handle curved block salt

Your Minimax Innova Water Softener uses revolutionary Mini Curved Block salt to function, which needs to be replenished regularly so you have an uninterrupted softened water supply.  Each block is 2.15kg, making it lighter to carry, smaller in size and easier to handle and store.  

High flow rates

The Minimax Innova is designed for all homes and works with all types of plumbing systems. With a flow rate of 51 litres per minute (with minimal pressure loss), this is the water softener for you and your home.

Strong robust design

The new cutting edge Minimax Innova Water Softener is designed and manufactured in Britain, specifically for our plumbing systems.  new recycling technology allows the Minimax Innova to use 62% recycled plastic in its cabinet material.

Accurate metering for maximum flow rates

Displacement meters mean accurate regeneration, low salt costs and efficient water usage.

Twin-cylinder design for 24 hours of softened water

The twin-cylinder allows for softened water 24 hours a day with more than enough capacity to supply softened water to a large family home.

I needed to replace an old water softener and contacted Cotswold Water Softeners on the basis of their excellent reviews - I will add another one! They are a very professional and friendly company, with great communications and punctuality. The survey was very good, with lots of useful information from Tim. The installation by Simon was first class, very neat indeed and we're delighted with the finished product. I would highly recommend Cotswold Water Softeners.
