A 500 ml bottle of central‑heating inhibitor paired with a handy radiator dosing funnel and a flexible drain‑tube gives you everything needed to keep your heating system running clean and quiet.
Why use the inhibitor?
The concentrate protects metal parts—radiators, pipes and the boiler—from rust and limescale, blocks hydrogen gassing, and limits microbiological growth. The result is smoother water flow, faster heat‑up times and noticeably less boiler noise.
How it works:
1. Attach the nylon‑brass funnel (1 L capacity) to any ½” BSP tap on your radiator.
2. Pour the inhibitor into the funnel; gravity does the rest—no spills, no mess.
3. When it’s time to flush, place the rubber drain tub (1.4 L) under the pipe. Its stretchable openings fit 10‑22 mm pipe sizes and work in both vertical and horizontal positions.
