Adey ElectroScale2 Compression Scale Reducer

The Adey ElectroScale2 is a smart, maintenance-free solution for tackling limescale build-up in domestic and small commercial water systems. If you live in a hard water area, limescale can quietly cause damage to your plumbing and appliances—reducing efficiency, increasing energy bills, and shortening equipment life. ElectroScale2 offers an effective, environmentally friendly way to prevent these issues before they start. This WRAS-approved electrolytic water conditioner works without chemicals or electricity. Instead, it uses an internal electrolytic cell to alter the crystal structure of the minerals that form limescale. As water flows through the device, this structure change makes the minerals far less likely to stick to pipework, heating elements, and internal boiler components. One of the key advantages of the ElectroScale2 is that it’s truly a "fit and forget" product. There are no running costs, no power requirements, and no maintenance schedules to worry about. Once installed, it provides immediate and long-term protection against limescale—helping your central heating and hot water systems run more efficiently, saving you energy and extending the life of your appliances. The device is Part L Building Regulation compliant, which means it meets the requirement for treating feed water to combination boilers and water heaters to reduce limescale accumulation. With a simple compression slip socket design, installation is quick and easy—perfect for both professional plumbers and confident DIYers. Available in 15mm or 22mm sizes to suit different pipework.

Frequently Asked Questions

It uses an electrolytic cell to change the way minerals in the water crystallise. This process doesn’t remove the minerals, but makes them less likely to stick to pipes and heating elements, helping to reduce scale build-up naturally.

Does the ElectroScale2 need electricity or batteries?

No, it operates without any power supply. It’s a passive device that uses water flow and internal components to work—completely maintenance-free and with zero running costs.

Is this compliant with UK building regulations?

Yes, it fully complies with Part L of the Building Regulations, which require scale-reducing measures to be installed on feed water lines to water heaters and combination boilers in hard water areas.
