The Allen Consulting Group, for the Department of the Environment, Water, Heritage and Arts, 2009
The Department of the Environment, Water, Heritage and the Arts commissioned The Allen Consulting Group to complete a report on WELS Expansion - Hot Water Circulators.
This cost benefit analysis found that whilst hot water circulators have the potential to save water, they cannot be rated for water efficiency because all hot water circulators will provide similar levels of water savings when assessed under identical 'test' conditions.
The Allen Consulting Group supports the conclusion made in the Coomes (2008) report that while hot water circulators can make a contribution to national water conservation, they are not a suitable product for inclusion in the WELS scheme because the notion of relative performance (of hot water circulators ) does not apply.
