Abstract

For the inhibition of ice formation in a pipe such as the condensate-pipe (13) of a gas fired boiler (11), air at a temperature above the temperature at the pipe outlet (17) is introduced (21) into the pipe and forced to flow through the pipe in a direction towards the pipe outlet. A temperature sensor may be provided in the vicinity of the pipe outlet to enable the flow of air through the pipe to be confined to periods when the sensed temperature is below a pre-determined temperature.
