British Antarctic Survey uses heating cable

We should worry about the wrong kind of snow – down at the British Antarctic Survey, Rothera research station on Adelaide Island the snow melts, water gets under the garage door, then refreezes and the doors won’t open.

To solve the problem they have used the same trace heating cable supplier as they use to keep the water and sewage mains pipework frost free. So when the new powered doors were installed a concrete base slab was put in containing 140m of ViaGard trace heating cable. It comprises a heavy braid and a thick, pressure-extruded jacket able to withstand course concrete. The cable energises when snow and/or ice is detectd on the surface giving off more heat in colder weather.
