What is a water conditioner, and how does it work?A water conditioner is a device that alters the structure of minerals—mainly calcium and magnesium—in hard water to reduce scale build-up. Unlike traditional water softeners, conditioners do not remove these minerals but instead neutralise their ability to stick to surfaces like pipes and boilers.
-
How is a water conditioner different from a water softener?Water conditioners are salt-free, maintenance-free, and environmentally friendly. Water softeners use salt and require regular maintenance to remove hardness minerals from the water. Conditioners are ideal for households that want to avoid ongoing maintenance or salt handling, especially in areas where water softener discharge is restricted.
-
Will a water conditioner improve my water pressure or flow?Water conditioners don’t directly increase water pressure, but by preventing limescale build-up inside pipes and appliances, they can help maintain optimal flow and efficiency over time.
-
Do water conditioners remove existing scale?Some advanced systems may gradually break down existing limescale over time, but they are primarily designed to prevent new scale from forming. For heavily scaled systems, we may recommend a one-off descaling treatment alongside the installation.
-
Is a water conditioner safe for drinking water?Yes, absolutely. Because water conditioners do not add or remove anything from your water, your drinking water remains safe, natural, and mineral-rich—ideal for cooking, pets, and children.
-
How long does installation take?Most water conditioners can be installed in under 2 hours by our professional engineers. There’s no major disruption, and the system starts working immediately after setup.
-
How long do water conditioners last?Quality water conditioners typically last 10–15 years or more, depending on the model and water quality. They are virtually maintenance-free and cost-effective over their lifetime.
-
Do I need to service or replace filters?No filters or salt are used with water conditioners, so there’s no ongoing servicing required. Just install and enjoy the benefits.
-
Can I install a water conditioner with a combi boiler or megaflo system?Yes! Water conditioners are compatible with all types of domestic heating systems, including combi boilers, unvented cylinders (megaflo), and conventional setups.
