Not only is it important that our Recoh-vert, RV-3, does what it says on the tin, but it is critical our customers do not realise it is there, due to noise or even smell!  We have therefore bought to bear our experiences from the past.  It was clear there were some issues regarding noise and smell with our earlier versions.  So we decided that we needed a twin wall around the heat exchanger to remove these problems.  This is now in place for all systems using both RV-2 and Rv-3 models.  We tell you to ensure the system is not insulated when installed, in doing so we are often questioned, as normally a soil and vent pipe would be insulated to prevent noise.  The twin copper wall negates the need for insulation.  Systems with a single wall will also require an "air break to drain" to prevent the build up of condensation, this can cause smell as the drain is open.  Again, the twin wall copper prevents the need for the "air break to drain". The attached Why we switched from a single wall WWHRS to a double wlled system shows how important this was to one of our key installers in Holland. We believe this is unique to Showersave, it adds weight, it adds to manufacturing cost, but we have a better product that has proven its worth in so many buildings to date.

  “Taylor Wimpey has specified the use of Showersave in a number of our properties where it helps us to achieve our energy reduction targets in a cost effective manner.  It is a straightforward technology which delivers benefits to not only us, as the house builder, but more importantly our customers in terms of their heating bills.  As a passive system it is simple to install and does not suffer from ongoing or additional maintenance unlike some other forms of technology, ultimately benefiting our customers.”   Taylor Wimpey Technical
