Salt-Based Ion Exchange Softeners: These are the most effective traditional systems. They work by swapping hardness minerals (calcium and magnesium) for sodium using a resin bed. Best for whole-home protection, including boilers, taps, and appliances. Often installed on the mains water supply before it reaches the heating system.
Salt-Free Water Conditioners:
These don’t remove hardness minerals but alter their structure so they don’t stick to surfaces — reducing scale build-up. Ideal for smaller homes or where salt-based units aren’t practical. Low maintenance and more eco-friendly, but not as effective for extremely hard water.
Electromagnetic or Electronic Descalers: These clamp onto pipes and use electromagnetic fields to change the behaviour of mineral ions, helping reduce scale formation. Easy to install and maintain — perfect for retrofitting in tight spaces.
Best for light to moderate hard water areas; effectiveness can vary.
Inline Scale Reducers: Compact devices fitted to the cold water inlet of a boiler or combi system. They use polyphosphate or electrolytic action to reduce scale.
Affordable and easy to install — ideal for targeted boiler protection. Often required to comply with boiler manufacturer warranties.
Water softeners play a crucial role in protecting your boiler and heating system, especially in hard water areas. They help shield heat exchangers and internal components from damaging scale build-up, which can significantly reduce efficiency over time. By softening the water, you maintain optimal boiler performance, improve hot water flow, and lower energy consumption. This not only enhances day-to-day comfort but also cuts down on costly repairs and extends the overall lifespan of the system.
At Mirage Heating & Plumbing, we offer a wide range of water softeners and scale protection solutions designed for both domestic and commercial systems — helping you keep everything running clean, efficient, and reliable.
GOOD Based on 24 reviews Jack M2024-04-18Trustindex verifies that the original source of the review is Google. The best supply shop in SW London, stock levels and knowledge are invaluable. Family run and they know their stuff. The AFC Wimbledon sponsor is a benefit too! samaiar2023-11-15Trustindex verifies that the original source of the review is Google. Good, knowledgeable merchants with a lot of boiler parts in stock which a lot of places don't do. Also open longer than the other boiler spares shops on a Saturday which is a plus!
