I don't think so (I'd wager too much transmission loss), but pumping heat directly through some other , more efficient transfer medium from a plentiful source (like geothermal energy) might be viable. That heat energy can be directly applied to hot water geysers, central heating, etc etc - basically anywhere you could use a furnace, and some places you can't.
