Why Bleed Your Radiators?

Air trapped inside a radiator prevents hot water from circulating properly, leading to cold spots and reduced heating efficiency. Regularly bleeding your radiators is a simple maintenance step that can improve home comfort and reduce energy use.

Frequently Asked Questions

Q: What size radiator bleed valve does this wrench key fit?

A: This radiator bleed key is designed to fit standard 6mm square spool bleed valves, which are the most common type found on residential radiators and hot water heating systems.

Q: Is the radiator bleed key coated to prevent rust?

A: Yes! Each iron bleed key features a rust-resistant yellow coating that helps protect the metal from moisture and oxidation, ensuring long-term durability even in damp bathroom or utility room environments.

Q: Why do I get two keys in this set?

A: The 2-pack value set is ideal for homeowners with multiple radiators or multiple floors. Keep one key upstairs and one downstairs, or store a spare in your toolbox so you always have one on hand when it's time for routine radiator maintenance.

Q: How do I use a radiator bleed key?

A: Insert the square end of the bleed key into the bleed valve located at the top of your radiator. Turn it counter-clockwise slowly until you hear air hissing out. Once water begins to drip steadily from the valve, close it by turning clockwise. Always place a cloth or small container below the valve to catch any water drips.
