Water temperature of incoming ground water varies throughout Canada. While the Greater Vancouver area (metro) may experience 40 degree F in the winter months, other areas may struggle to reach 35 degrees F. For our purposes here, we are using 40 degree F (4 degree C) as the temperature of the incoming ground water as a worse case scenario. The water temperature in the summer months can reach 60 degrees F in the metro area, so values change.

105 degrees F (41 degrees C) is generally accepted as the standard for shower and bathing purposes. New construction faucets and shower heads limit the flow to 2.5 imperial gallons per minute (GPM) which equates to 3 US GPM.
