    Thank you! Nothing like real world experience.

    Cool. Hadn't heard of them before.

    I chose Power-Pipe because:
    - it had been tested by the National Research Council (Canadian Govt Agency) for efficiency (rather than just having manufacturer-reported numbers)
    - it was on the Government approved list for rebates (ecoEnergy program) http://oee.nrcan.gc.ca/residential/p...retrofit/13302
    - it had the highest efficiency rating (for the size) of all units tested
    - it was available at Sears and Big Orange (in case I had to return it).

    ShowerSave says their 2.1 metre tall unit has an efficiency of 66% (http://www.showersave.net/about/what-is-shower-save/), whereas the same size of Power-Pipe (R4-84) has an efficiency of 66.7% (essentially the same).

    So I'd choose whichever one was more convenient to get (or cheaper). It looks like the ShowerSave is around $1500, whereas the Power-Pipe only cost me $695 from Sears.ca

    Either way, it's worth doing.
