We are pleased to announce that as of 30 June 2011 the RV-3 has been uploaded into the Products Characteristics
Database (PCDB) of SAP 2009. In addition, BRE has recognised that there are different ways in which the systems (RV-
2, RV-3) can now be installed. These developments will allow UK house builders to achieve the Code levels at a lower
cost. The real benefit will depend on the house type, size, occupancy, fuel displaced and the number of baths and
The Showersave Recoh-vert, RV-3 is recognised by BRE to be 5% more efficient than its predecessor the RV-2. This is
likely to translate to a significant up lift in points to achieve Code 3 & 4. The Showersave Recoh-vert, RV-3 is installed in
the same way to the RV-2, it looks exactly the same. The enhancements have been made to the heat exchange unit
within the pipe. We are supplying this product at no extra cost to the end user. A new installation manual will be included
with unit dispatched.
