A V2 radiator booster replaces a 15mm lockshield valve and screws directly into the bottom of a radiator. Depending on which side you want to fit the booster, for thermostatic control you should consider swapping over the thermostatic valve with the lockshield valve.
There are two ‘tails’ either side at the bottom of the radiator, and a V2 radiator can either push water through the radiator or pull water from the radiator.
If you have a double radiator, the distance to the wall allows you to fit a radiator booster without removing the radiator, but you will need to remove the radiator from the wall if you want to fit a V2 radiator booster to a single radiator.
This post will take you step by step through the process for fitting a V2 radiator booster onto a single radiator.
Booster orientated to push water through a radiator
Use an adjustable to remove the existing tail
Remove the existing tail and unscrew the compression nut from the V2 booster
Wrap the thread of the V2 with the tape we provided
Screw in the V2 Radiator Booster
V2 booster fitted, but remember to fit another valve so you can isolate the radiator and the V2 booster if required.
To pull water from a radiator, simply rotate the V2 booster.
With the motor of the V2 radiator booster horizontal, there is a little less risk of air being trapped in the pump volute and reducing the pump efficiency, but pushing water through a radiator or pulling it through a radiator will make very little difference to a standard radiator.
