Equal Flow Configuration Send the preheated water to the inlet of the shower and to the hot water tank SAVINGS FACTOR: This is the preferred installation because is it offers the greatest energy savings RENOVATION FACTOR: This is the most complex in terms of installation and cost DESCRIPTION OF PROCESS Water heater uses less energy, it only has to heat up warm water from (26 C to 60 C), at the shower, you are using less hot water because you are now mixing warm water with hot water (26 C with 60 C) To take full advantage of the ThermoDrain heat recovery capabilities we recommend that you install your ThermoDrain in an equal flow configuration.
Cold Water Preheat Configuration Send the cold water to the outlet of the shower SAVINGS FACTOR: 89% savings compared to that of an equal flow configuration RENOVATION FACTOR: Lowest cost due to simplicity and material required. This is the simplest of all 3 installations. DESCRIPTION OF PROCESS Less hot water is used because you are mixing warm water (26 C) with hot water (60 C)
