Central Heating Cleaner Kit – 500ml Concentrate, Funnel & Drain Pan

A 500 ml concentrate, a handy dosing funnel and a flexible drain pan – everything you need to give your central‑heating system a deep clean in one simple step.

What’s inside
– 500 ml cleaning concentrate – powerful enough to treat a typical 10‑radiator circuit, it dissolves rust, limescale, sludge and debris that slow water flow.
– 1 L radiator dosing funnel – nylon body with a brass ½″ BSP swivel joint fits 99 % of radiators. Pour the concentrate and let gravity do the work; the funnel fills in about 17 seconds and prevents spills.
– 1.4 L drain tub – rubber construction with stretchable 10‑22 mm pipe openings, suitable for both vertical and horizontal pipes at any angle.

Why it matters
– Restores smooth water circulation for faster, more even heating.
– Reduces cold spots and improves boiler efficiency.
– Works with a range of chemicals (inhibitor, leak sealer, anti‑freeze, etc.).

Easy to use
1. Attach the funnel to the radiator’s ½″ BSP tap.
2. Pour the concentrate from the marked bottle.
3. Collect the runoff in the drain tub and dispose safely.
