| 摘要 |
A biocidal treatment device is disclosed which comprises at least one gas water heater arranged to produce heated water for use in biocidal treatment, connection means for facilitating connection to at least one gaseous fuel source arranged to store and supply gaseous fuel during use to the at least one gas water heater, at least one gas conduit extending between the connection means and the at least one gas water heater, and a liquid reservoir. A portion of the at least one gas conduit extends through the liquid reservoir so as to facilitate transfer of heat to the at least one gas conduit during use and thereby restrict freezing of the gas conduit during use. The liquid reservoir may be a water reservoir arranged to store and supply water to the at least one gas water heater.
