#2 Can I take off the wheels/castors on this heater?
Yes, you can remove the castor plates from this metal panel heater if you decide you want to wall mount it.
You may find that when the castor plates were installed, there were 1-way screws used which means you will not be able to use a screwdriver to remove them.
You may need to use a pair of pliers to unscrew them or failing that use a drill to remove the head of the screw and then you should be able to remove the castor plates. Remember to remove the remaining part of the screw as it will be sharp.
