We investigate the ability of ion-neutral interactions to dissipate Alfv\'en waves in the solar chromosphere. An acoustic driver is used to generate perturbations in a self-similar magnetohydrostatic flux tube model. As these waves travel into the centre of the magnetic field concentration, where plasma $\beta dissipate a significant amount of energy, a factor of 20 higher than the dissipation of static currents. This heating is caused by the damping of magnetic waves, as seen by a decrease in Poynting flux by up to $90\%$ when ambipolar diffusion is included. The dependence of this energy dissipation with resolution, driver amplitude and frequency is studied.
