HOT WATER HEATING
CONTINUOUS FLOW
SYSTEMS SHOWS
DRAMATIC SAVINGS –
SAYS INDEPENDENT
REPORT
A recent independent report emphatically
concluded that continuous fl ow water heating
systems have a clear advantage in terms of initial
capital costs as well as life cycle costs over 20
years, when compared with traditional stored
hot water systems*. indirect system then it has to eff ectively shut
down for maintenance. There’s no way around
this problem. Not so with Rinnai continuous
fl ow units as we cascade them together so that
the demand for hot water can be met without
closing down the whole site.”
The study** shows that continuous fl ow
water heating systems can be up to 7% more
economical than equivalent ‘traditional’ stored
hot water systems but that capital costs can be
41% less than indirect systems and a whopping
49% less than direct systems. AECOM, the world’s biggest building services
consultants, was commissioned to carry out
a totally independent life cycle study on
continuous fl ow water heating systems, and to
provide a comparison with conventional storage
systems. Two case studies were provided on
projects using continuous fl ow water heating
systems.
“In terms of maintenance you need to be realistic
and not theoretical,” says Rinnai managing
director Tony Gittings. “If a site has direct or an
AECOM then determine
