Aluminum Heat Transfer System

Aluminum Heat Transfer System

Aluminum Heat Transfer System are formed aluminum plates specifically designed to pro- vide excellent heat transfer between radiant heating pipes and floors or other surfaces. They may also be used to transfer heat to various other mechanically secure surfaces in a wall or ceiling installation. HWALU heat transfer plates are a critical component of a properly designed radiant system increasing the efficiency and the reaction time of the system.

HWALU Aluminum Heat Transfer System

  1. Increases heat transfer by over 30%
  2. C-Channel design for better tubing contact and holding tubes in place
  3. Precise thickness to optimize efficiency - thicker than the other guys!
  4. Lower water temperatures
  5. Lower heating bills
  6. Great for retrofits and new construction


HWALU Aluminum Heat Transfer System are formed aluminum plates specifically designed to pro- vide excellent heat transfer between radiant heating pipes and floors or other surfaces. 

Aluminum Heat Transfer System are typically used when installing radiant tubing under existing floorsorin new installations with wood or other floor materials to be placed on top of the floor base. They may also be used to transfer heat to various other mechanically secure surfaces in a wall or ceiling installation.

Aluminum Heat Transfer System are a critical component of a properly designed radiant system increasing the efficiency and the reaction time of the system.

Good radiant heating is done at low water temperatures and in the case of staple-up, that means with plates.

Staple up without heat transfer plates. These system will run lower than suspend tube system but hotter than plate type system due to less conductive surface.

Staple up with heat transfer plates. These system will run at a lower temperature than to the addition of aluminum fins which extend the contact surface area.

Why?

1) The tubing will last longer.
2) Lower temperatures means less heat loss through the boiler, primary piping and tubing.
3) Fewer expansion and contraction noises.

The use of transfer plates in under floor heating is (in my opinion)the only way to go.
If you just put in more tubing per square foot your still relying on convection rather than conduction. Aluminum Heat Transfer System are designed to transfer the heat across the entire surface. With just the tubing, your heating the air space and trying to heat your living space via the hotter air under your flooring. Although the tubing is in direct contact with the floor, your not going to be able to get more than 8 inches on center with 1/2. Unless you plan on running several tubes down one bay, thus increasing your costs on manifolds ect. The btu's that are distributed with the plates and astro foil 5/8 of an inch under the plates yeilds 46 btu's per square foot.


The following flooring types may be installed above this type of system:

i. Nail-down solid hardwood
ii. Floating hardwood
iii. Engineered hardwood
iv. Glue-down wood flooring
v. Carpet (broadloom or tiles)
vi. Vinyl (sheet or tiles)
vii. Ceramic tile

Features Of Aluminum Heat Transfer System

  1. High Quality Aluminum Heat Transfer Plates for 1/2" PEX Tubing
  2. High Quality Aluminum Plates for Fast Heat Transfer
  3. Allow 1-2 inch spacing between plates for expansion
  4. 0.016 Thick Aluminum 4.5" wide

Advantage Of Aluminum Heat Transfer System

  1. These die-formed aluminum heat plates snap into the grid modules and help conduct heat from the tubing into the floor.
  2. They're also used in staple-up systems to secure PEX tubing to the underside of the sub-floor to maintain contact between the tubing and the sub-floor.
  3. Excellent way to transfer heat when used with either 1/2 in or 5/8 in PEX tubing
  4. Easy to install
  5. Reduces energy cost
  6. Increases comfort
  7. Convenient for use in staple up systems

Applications Of Aluminum Heat Transfer System

Under the Sub-floor installation - Between Floor Joist - Engineered Floor Boards - Between plywood installation (Sandwich Installation)
