Hot-points are designed for producing boreholes without a core by melting ice and used to install ablation sticks, to determine ice thickness, to locate englacial and subglacial streams, to deploy sensors and tools under ice shelves, to measure temperatures and closure rates of glaciers, to study subglacial environment in Earth and other planets. The energy for the melting tip heater is provided by a hot fluid that is pumped down using hoses in a closed circuit or by electricity transported via electrical cable.
