The stoves have been doing much of the heating, but occasionally, when away for a longer period of time, the heat pump kicks on. Last year, with a lot of the snow, the top would get covered and ice would form, creating an annoying sound when fan hit it. Expected a little snow tonight so I was wondering if there if anything I could do/build to prevent the snow and ice from covering/preventing it from running properly if needed. Something simple that I could put in place if snow is expected and remove later? If I build something simple I could place several feet over the fan, would that prevent the hp from working properly? Or, should I just leave it alone? Just curious.
