A method for inhibition of ice formation in a pipe comprises providing a source of air at a temperature above the temperature at the pipe outlet 17 and introducing 21 a forced flow of air through the pipe in a direction towards the pipe outlet. In a further aspect, an icing inhibitor 20 for inhibiting formation of ice in a pipe, such as the condensate pipe 13 of a gas fired boiler 11 or air conditioner, comprises an enclosure 22 having an air inlet port 26 and an air outlet port 30 for connection to a pipe. The enclosure contains an electrically powered fan 28 for inducing air to flow into the enclosure through the air inlet port, and an electrically powered heater element 29. The icing inhibitor has an associated temperature sensor 36 for responding to temperature at or in the vicinity of the outlet end of the pipe and a controller (39, fig.4) to control the supply of electrical power to the heater as a function of the temperature sensed by the temperature sensor. In a still further aspect, a pipe icing inhibition installation 10 comprising an appliance which emits water, either as liquid or vapour, is disclosed.
