Abstract
An ice fishing hole heater comprises a housing defining an open topped cavity adapted to receive a combustible fuel source. Heater is constructed so that the specific gravity of the housing and the heat source enables the heater to be buoyantly supported in a body of water. The housing also includes ballast weight to maintain the housing in an upright position. Preferably, the housing includes a radially expanded ring which is hollow to stabilize the housing as it floats and which floats at the surface level of the body of water to radiate heat from an expanded surface area into the water in the hole.
