We show the changes in atmospheric and surface temperature when latent heat is implemented self-consistently in our code. Latent heat cools the surface when evaporating and warms the atmosphere when condensing, because we assume that condensation occurs aloft. As predicted by E. S. Kite et al. (2016), temperature changes due to latent heating are negligible at the surface but warm the atmosphere a little. However, the changes are minor, with the exception of K2-141b, where atmospheric temperatures can warm by 10%. This is due to the relatively large condensation rate but relatively low radiative heating and cooling caused by orbiting around a cooler star.
