hi, can you zoom to the extent of the heatmap layer? There is a reported (and already fixed for 2.8.2) issue ( http://hub.qgis.org/issues/12264 ) about projection of the "heatmap layer" and a solution proposed here ( http://gis.stackexchange.com/questions/137770/why-are-heatmaps-on-qgis-2-8-1-produced-in-the-wrong-crs )
