Snow sliding performance of the electrically heated roof-tiles (ERT) was examined using a model house from December 1988 to February 1990. For the purpose of economic and efficient operation, the roof was covered with the lines of ERTs and non heated tiles. Each line of ERTs is heated independently, hence the ratio of heated area of the whole roof can be set at each sliding test. When a half or a third of the total area of the whole roof was covered with ERTs, snow sliding was achieved, though simultaneous sliding rarely occured in the whole roof surface and some snow left. The difference in surface temperature of non-heated tiles put between the lines of ERTs signiffi-cantly affects the sliding performance.
