Abstract, Apparatus for determining the heat transfer efficiency of a heat exchanger wall is disclosed. The apparatus is designed for ease of use and simplicity and comprises heating means for imposing a heat load on a first heat transfer surface of the wall and means for determining the rate of dissipation of the heat load across the wall and into a heat exchange fluid in contact with a second heat transfer surface. By determining the rate of heat dissipation across the wall and into the heat exchange fluid the heat transfer efficiency of the wall and the overall cleanliness thereof can be evaluated. -1-
