GFX Heat Recovery Units
Every time you take a shower, 95 degree water is wasted as it goes
down the drain. The Waste Heat recovery technique transfers heat
from the outgoing hot waste water to the incoming fresh water that is
replenishing your hot water tank. The Waste Heat recovery unit is
simply designed, having no moving parts or electrical components.
Waste Heat Recovery Energy Savings Example:
4 Showers per day
2.25 Gallons per minute (Low flow shower head)
12 Minute Showers (National Average)
Electricity @ 7.30 cents/kWh (Puget Sound Energy, 6am-10am, Oct 2001 Est.)
60” Waste Heat Recovery Unit (Model S3-60)
95 Degree Drain Water Temp (Average shower drain temp)
An estimated $115 Utility Savings per Year
This would be a 29.95% per year return on your initial investment, for as long as you keep taking
showers. Where else can you make those kind of returns?

What is Heat Pipe Technology ?
R & D work for the SEIDO line of evacuated tubes using heat pipe technology was carried out by the
Daimler-Benz Aerospace Group, in cooperation with Beijing SUNDA Solar Energy Technology Company,
based on experience gained in the temperature control of satellite electronics.
The main component of a SEIDO collector is the aluminum absorber mounted in an evacuated glass tube.
The absorber, coated with a special aluminum nitride layer, converts incoming solar radiation to heat. The
special coating absorbs more than 92% of the arriving radiation, but radiates less than 8% back to the
environment.
Heat transfer from the absorber to the fluid circuit is performed by the “heat pipe”. A heat pipe is a closed
system, carefully evacuated and charged with a small amount of water before it is sealed. The absorber
imparts heat to this water, causing it to evaporate. The steam rises to the upper end of the heat pipe where
it transfers heat to the fluid circuit via a metallic conduction bridge. Being a “dry” connection, fluid in the
heating circuit does not flow through the collector.
The absorber and heat pipe are mounted in a sealed evacuated glass tube, cutting heat losses via conduction
and convection. The stable vacuum assures that the collector performs at low outside temperatures and
protects the absorber against the environment.
