ABSTRACT:
A water supply system for a building provides extraction of radon from the water using a hot water tank which is supplied with cold inlet water via a float valve with the tank closed apart from hot water outlet and a vent to the atmosphere of sufficient size to allow escape of gases coming out of solution from the water in the tank. The water is heated to a temperature preferably above the desired temperature and then recooled in a heat exchanger cooperating with the cold inlet. The heat exchanger can supply both heated water and cooled water from the water extracted from the hot tank. This technique extracts up to 90% of the radon with very little additional equipment of energy costs.
