There's many cases where no particles get exchanged. Another common form of energy, kinetic energy, can be transferred from one body to another with no particles getting exchanged. For example the Voyager flybys of Jupiter imparted enough energy on the spacecraft to allow them to reach escape velocity from the sun, kinetic energy which they didn't have prior to their encounters with Jupiter.
In quantum physics particle mediators are usually associated with (dynamic) forces, not energy.
