I want to remove one of my central heating radiators to decorate. The themostatic valve is on the left as you look at the radiator, and the nut on this valve nearest the radiator unscrews by turning it clockwise as you look side on to the radiator. How about the nut nearest the radiator on the right hand side. Would that unscrew by turning it anti clockwise? Its quite tight and I want to be sure before I use more force.
