The Vital Aqua hot water only unit is an alternative to a standard electric hot water heater that may be used to provide hot water to cleaner cupboards in a communal block area, or to simply supply washing up water above a sink.
The Vital Aqua contains the standard features common to all the Vital range, although with no heating circuit components, there are only 4 connections to each HIU.
