Automatic Radiator Bleeder - throw away your radiator key and feel the extra warmth

This new radiator bleeder is easy to fit and automatically releases air from any central heating radiator, ensuring that only hot water remains and so maintaining maximum heat.

During normal running of the central heating, air can build up in the system, reducing radiator heat and efficiency. This is fixed by bleeding the radiators, but by fitting the Auto Vent, radiators are bled automatically, without you needing to do anything.

The result is a hot to the top radiator from the same energy, and lower heating bills.

Fitting is simple and requires only an adjustable spanner. Usually only one Auto Vent is required*. Available in two models, standard and micro - that fit all known radiators.

To order, choose which model, then click on add to basket, or read on for more information.

More information

* Only one Auto Vent is required, as usually one radiator is prone to the air problem more than the others in the system.

Easy fit: no adjustments necessary no need to drain the system

Long, leak-free life

Replaceable cartridge

Saves energy and reduces fuel bills by keeping radiators air-free and hot to the top

Dispenses with the need for radiator bleed keys

Reduces corrosion and system noise

The HV30C operates vertically and horizontally on 1/2" tappings.
(This is the one to choose for standard home radiators and modern towel rails**).

The Micro operates on 5/6/7 mm 1/8" and 1/4" tappings.
(For specialist design radiators, such as cast iron radiators, some towel rails, Quinn (Barlo) radiators, and Center radiators)

** How do I find out the size of my radiator tapping?
For a 1/2" British standard thread, the threaded hole in the tapping at the top of the radiator is approximately 20mm diameter - you should be able to fit your index finger in the tapping. The plug screwed in to the tapping will either be a chrome hexagonal valve, or a 'plug' with a square cavity in it.

Fitting instructions

Installing the auto vent is a simple DIY job that doesn’t require system draining:

Turn central heating off and allow to cool

Turn the chosen radiator off, by closing the valves at the bottom at both ends (one end is a Lockshield valve with a spindle - turn with your adjustable spanner, at the other end, turn the Wheelhead or Thermostatic valve to 0 by hand)

Remove the old vent pin using your radiator key

Fit the new auto vent

Turn radiator back on!
