We investigate the basic charge and heat transport properties of charge neutral epigraphene at sub-kelvin temperatures, demonstrating a nearly logarithmic dependence of electrical conductivity over more than two decades in temperature. Using graphenes sheet conductance as an in situ thermometer, we present a measurement of electron-phonon heat transport at mK temperatures and show that it obeys the T-4 dependence characteristic for a clean two-dimensional conductor. Based on our measurement, we predict the noise-equivalent power of similar to 10 - 22 W / <mml:msqrt> Hz</mml:msqrt> of the epigraphene bolometer at the low end of achievable temperatures.
