Heat Recovery Unit for shower

[C Williams]

My point was that the temperature of the Cold/Warm output stabilizes very quickly (<30 seconds) and so you don't need to be constantly adjusting the hot/warm mix in your shower.

Thank you! Nothing like real world experience.

It's a huge stress reliever when I hear my kids' showers stretching on and on....

Try this system, more efficient than powerpipe in SAP for the same size, 2.1m length. installation methods outlined on web site www.showersave.net

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.
