A 22 mm electrolytic scale inhibitor designed for boilers and pipe‑work that keeps limescale at bay without chemicals or electricity. The compact unit fits easily into water‑to‑water heaters, combination boiler hot‑water circuits and any steel pipe system where hardness exceeds 200 ppm.
Key benefits
– Energy‑saving – reduces scale build‑up on heat exchangers, helping the boiler run more efficiently.
– Zero‑maintenance – no moving parts or consumables; the device works for up to ten years depending on water usage.
– WRAS approved & UK‑made – meets British standards for pressure (10 bar @ 20 °C) and durability.
– Simple installation – 22 mm compression fittings, can be mounted horizontally or vertically, and requires only a standard 24 mm spanner.
How it works
As water passes through the chamber, a low‑voltage electrolytic cell releases charged zinc ions. These ions cause hardness salts to clump together and flow straight through the system instead of depositing on heating elements.
Installation tips
1. Position the unit where it’s easy to access for inspection or replacement.
2. Fit an approved check valve or equivalent back‑flow preventer at the supply connection.
3. Cut the pipe squarely with a pipe cutter; tighten the fittings with a 24 mm spanner for a leak‑free seal.
Ideal for homeowners looking to comply with Part L of the Building Regulations and anyone who wants a reliable, chemical‑free solution to protect their boiler and pipework from costly scale damage.
