Water Softener & Tank Installation in Bournemouth

A water softener removes the calcium and magnesium minerals that cause hard water, replacing them with sodium ions through a process called ion exchange. Hard water causes limescale build-up in pipes, boilers and appliances, reducing their efficiency and lifespan. We install water softeners across Bournemouth, Poole and Dorset — areas where hard water is a well-documented issue — helping protect your home's plumbing and heating system long term.

Bournemouth, Poole and the wider Dorset area are classified as hard to very hard water regions, so your water contains elevated levels of calcium and magnesium. Over time that causes limescale in boilers, hot water cylinders, taps and appliances. Installing a water softener protects your heating system, extends appliance life, and can reduce energy bills caused by limescale-coated heating elements. We can assess your property and recommend the right unit.

A vented (open) water tank is fed by gravity from a cold water storage cistern, typically in the loft, and relies on height for pressure. An unvented water tank connects directly to the mains supply, delivering higher and more consistent pressure without needing a loft tank. We install both types and will advise which suits your property based on water pressure, available space and hot water demand. See our hot water cylinder page for more detail.

A standard cold water tank replacement or new loft tank installation typically takes between 2 and 4 hours for a straightforward job. Installing a new hot water cylinder or unvented system may take a full day, depending on pipework requirements and access. We carry out most water tank installations in a single visit, with all components — Byelaw 30 kits, ball valves and pipework connectors — supplied and fitted on the same day.

Cold water tanks start from £600 and feed expansion tanks from £250, with the final price depending on the tank size, access and pipework. Unvented hot water cylinder installations are priced separately. We provide free, no-obligation quotes with transparent pricing and no call-out fees — see our pricing page for the full list.

Yes, in a positive way. Softened water significantly reduces limescale build-up inside your boiler's heat exchanger, pipes and radiators, which is one of the most common causes of reduced efficiency and boiler breakdowns in hard water areas like Dorset. Pairing a water softener with a boiler service or power flush gives your system maximum long-term protection and helps keep the manufacturer warranty valid.

The right size depends on the number of occupants, bathrooms and peak hot water demand. As a general guide, a household of 1 to 3 people typically needs a 120 to 150 litre cylinder, while larger homes with 4 or more people and several bathrooms may need 180 to 250 litres or more. For loft installations with limited access, we can supply long-profile tanks (coffin tanks) or dual smaller tanks that fit through standard loft hatches without losing capacity.

Yes. Water softeners need periodic top-ups of block or granular salt, typically every 4 to 8 weeks depending on household water usage and softener capacity. The resin bed should be checked annually, and the unit serviced every 1 to 2 years for best performance. We can advise on the right maintenance schedule for the unit installed and are available for ongoing servicing across Bournemouth, Poole and the surrounding Dorset area.
