I might be baked, but if you think about it, we are a satellite moon in similar relationship with our gas (giant) comprised sun.

That's wholly dependent on the objects' orbit around the host body (Elliptical orbits will produce more tidal heating, and the closer the periapsis to the host the stronger the heating), whether it's locked/resonant locked or not (a 1:1 tidal lock produces little heating, a 3:2 spin-orbit resonance requires an elliptical orbit but also doesnt produce much heating; see Mercury), and whether there's other bodies of sufficient mass orbiting the host to allow for orbital resonances.

If the EarthMoon has a nearly circular orbit, is tidally locked, and has no other sibling bodies orbiting the host, it's going to get fuck-all for heating. On the otherhand, throwing in a bunch of secondary bodies of sufficient mass in resonant/near resonant orbits will get ample heating. This is how Io and Europa get their energy to drive their activity. Enceladus around Saturn is in a 2:1 resonance with Dione, and the resultant tidal energy drives the southern polar jets.

Is tidal heating even material versus latent core heat and radioactive decay?
