Ultra-Fin™ Floor Heat Transfer Plates
MacDuffco Manufacturing Inc. is the sole manufacturer of their patented Ultra-Fin™
Radiant Floor Heating System – a revolutionary hydronic heating system for
wood-frame construction.
Their innovative Ultra-Fin™ system is changing the world of radiant heating.
With it’s advantages and cost savings, it makes radiant heating a viable
choice for more customers, not just for the wealthy. Thousands of homes in the
United States and Canada use the Ultra-Fin™ system, including regions where
outside temperatures drop as low as minus 60 °F (minus 50 °C), and that
number is growing exponentially.
The Ultra-Fin™ plate conducts the heat and warms the air in the joist
spaces, via hot air convection. The super-heated joist air quickly warms the entire
floor, converting it into a giant radiator. The floor in turn radiates comfortable
uniform heat throughout the living space above.
The Ultra-Fin™ system delivers more comfort for less cost. It's unique engineering
presents important technological advances over traditional radiant heating.

Installing Ultra-Fin™ Radiant Plates
To ensure maximum heating efficiency from the Ultra-Fin™ Heating System,
the aluminum plates must be completely and firmly attached to the tubing in the
correct location for your layout. The Ultra-Fins should be attached horizontally
for best performance. After being firmly attached, the Ultra-Fins can be rotated
into the proper horizontal position.
Position and space the Ultra-Fins between the joists as indicated in figure
2, (tubing spacing for 12" joist spacing), figure
3, (tubing spacing for 16" joist spacing) or (figure
4, tubing spacing for 19" joist spacing) from the Design Layout section.
Follow these guidelines to ensure firm attachment of the Ultra-Fins:
Attach the Ultra-Fins using the aluminum pop rivets provided.Make sure tubing
sections are straight before attaching each Ultra-Fin.
Compress both Ultra-Fin halves together before riveting.
If any rivets fail to connect/catch both halves of an Ultra-Fin, you can easily
remove the aluminum rivet with a pair of side cutters. Use a sheet metal screw
in place of the rivet to ensure the Ultra-Fin is firmly attached.
! Note !
Ensure tubing is straight before
Ultra-Fin™ plates are firmly attached.
(See figure 12 ----->)
Each installed Ultra-fin™ plate is actually made from a pair of aluminum
plates or 'fins' that is 6  inches
in total width. There are two types of fins, 8 inch fins and 10 inch fins. The
8 inch fins are 8 inches long, 3 3/4 inches wide and 16/1000 inches thick. They
are made for regions where the temperature does not go below –10 ° C,
and have 20 louvers that allow for airflow and create convection. The 10 inch
fins are 10 inches long, 3 3/4 inches wide and 16/1000 inches thick. They are
made for colder climates and have 25(?) louvers for airflow and convection. A
typical Ultra-Fin™ system installation in a 3,000 sq. ft. home might use
1,500 fins (750 plates).
Ultra-fin™ plates are designed to attach to 1/2 inch nominal (5/8 inch
OD) RigidPEX™ tubing. Pop rivets are used to securely fasten each Ultra-Fin™
plate together, clamping them securely to the tubing. This allows complete heat
transfer from the pipe to the Ultra-Fin™. The plates never come in contact
with the water in the system, and will never rust or corrode.
