Hot water storage system
Approved Document G, Sanitation, hot water safety and water efficiency, 2015 edition with 2016 amendments, defines a hot water storage system as:
‘…a vessel for storing:
a. heated wholesome hot water or softened wholesome hot water for subsequent use
b. water that is used to heat other water
together with any ancillary safety devices described in paragraphs 3.10 and 3.11 of this Approved Document and all other applicable operating devices.’
It suggests that ‘hot water storage system package’ means:
‘…a hot water storage system having the safety devices described in 3.10 and 3.17 of this Approved Document factory-fitted by the manufacturer, together with a kit containing other applicable devices supplied by the manufacturer to be fitted by the installer.’
And that ‘hot water storage system unit’ means:
‘…a hot water storage system having the safety devices described in 3.10 and 3.17 of this Approved Document and all other applicable operating devices factory-fitted by the manufacturer.’
