Adding heat exchange to Aqua Hot
Has anyone added a heat exchanger to an Aqua Hot system. I have a 2006 Windsor 40PDQ with computer workstation floor plan; no couch on passenger side (see photo). The front of my coach has trouble getting warm on cold days. I found that the vent under the file drawers is a 'dummy', there is no exchanger there. I would like to know if anyone with the same unit with a couch on the passenger side has a heat exchanger there.
Also, to add a heat exchanger I assume I only need to tap into the electric wiring and PEX that supplies the other exchangers in the front.
