Recovery the heat from your drain water in Rochester, NY and Finger Lakes
Drain Water Heat Recovery is the science of recovering wasted thermal energy going down the drain and using it to pre-heat incoming fresh cold water. One of the most substantial utility costs in all areas of life is water heating.DWHR systems can passively recover a significant portion of that wasted energy and provide operational cost savings, prolong the life of heating appliances, and extend the run-time of hot water usage.
How does Drain Water Heat Recovery Work?
Before DWHR:
- The cold water enters your home/water heater at 43°F
- The water heater heats it to 123°F
- The shower temperature is 105°F
- The water going down the drain has cooled to 99°F
- The cold water enters your home at 43°F
- The cold water is pre-heated to 72°F
- The water heater heats it to 123°F
- The shower temperature is 105°F
- The water going down the drain is now cooled to 73°
ACES-Energy has several ways to install your Drain Water Heat Recovery unit
The heat exchanger becomes part of your drainage stack, usually in your basement, by replacing a vertical section of the drain line. The coils become part of your fresh water supply line by diverting it through them. It can be installed with any combination of drainage pipe and fresh water piping (ie. ABS, PVC, cast iron, copper, PEX, etc). Only 4 plumbing connections are needed -- 2 for the coil and 2 for the drain (using no-hub connectors).
Units can be installed on the second floor, first floor, crawl space and basement – virtually anywhere there is access to a sufficiently tall section of VERTICAL waste pipe having waste hot water flowing through it, along with access to a cold water supply line. The heat exchanger may be installed in more than one location, as on-site conditions may allow. For best results, install as close to the exit of the main drain line as possible.
For maximum savings, use the Equal Flow configuration - plumb the pre-heated water from the unit to both the water heater and the cold line, feeding all plumbing fixtures. Preheating the cold water to fixtures like a shower significantly reduces the amount of hot water needed. This also creates an equal flow where the total preheated water being used is equal to the total water going down the drain.
