What has better heat transfer aluminum or stainless steel?
Stainless steel offers superior corrosion resistance and tensile strength at the cost of added weight. When dealing with heat, stainless steel offers better heat tolerance while aluminum offers better heat conductivity. However, aluminum's lower melting point makes it less applicable in high-temperature applications.

PEX heat transfer plate - extruded or aluminum sheet?
We are retrofitting an existing house with radiant heat under the floor. From my research, it seems clear that we should install aluminum heat transfer plates, but I haven't been able to determine if it's worth investing in an extruded aluminum C-shaped heat transfer plate (omega o or U-shaped) on top of a metal plate. Even if bought in bulk, extruded sheet i ...
Advantages of aluminum heat transfer plate in floor heating system 1) We have installed a chain processing line from aluminum ingots to aluminum heat transfer plates, which can reduce costs, control progress, and ensure quality.
2) As floor heating systems, our products ensure they cool down as fast as they heat up, which means you can turn it off at night and turn it back on in the morning for fast respo ...
1. In the first case, the aluminum fins do a good job of transferring more of the available energy from the hot water out of the pipe. In particular, aluminum fins place thermal energy directly on the underside of the floor to be heated, whereas ducts without aluminum fins primarily heat the air in the cavity and then transfer the air to the subfloor through inefficient mechanisms of warm air convection and condu ...
The principle of floor heating Floor heating actually uses the ground as a radiator, and then uses the radiant layer of the floor as a heat medium, so that the space floor can be fully and evenly heated. Through the effect of floor heating radiating upward, heating is carried out from bottom to top, so as to satisfy the heating of users. If it is a low temperature ground, it will form a gradually decreasing he ...
Why use heat transfer plates? Let's take the increased profit potential, longer heat transfer plate installation time, off the table. I see you can lower the water temperature. Due to the improved heat transfer efficiency, it can be reduced by a factor of 40-50. But wouldn't it be possible to get the same result by installing 2 to 3 times as much PEX per square foot? at a lower cost? Let's say a 5 ...
Omega Slot Heat Transfer Plates are an efficient way to distribute radiant heat from PEX tubes. HWALU Omega Heat Transfer Plates provide an efficient way to distribute radiant heat from PEX tubing. Made in China from polished aluminum sheet. The channels are wrap-around omega-shaped (ω) that fit snugly and very effectively hold the pipe in the system above ground level. Omega Heat Transfer Plate HWAL ...
One of the goals of this article is to enable installers to make better decisions on the job site. These decisions can range from modifying the layout to account for changes in the room to determining the effect of adding windows on heat loss from the room. To better solve these problems, you must understand how radiation systems work. All forms of heating are based on three basic modes of heat transfer: convecti ...
The following finite element analysis (FEA) study results compare the efficiency of fins using thick extruded and thin stamped aluminum sheets. The parameters of this study are: 120°F water temperature in pipes, 70°F air temperature above and below floor assembly, 8" pipe spacing, 1/2" PEX, 2.0 Btu/hr/ft2/F, 8" heat transfer coefficient x 1/32" stamped plate and 4" x 1/16" extruded plate with non-destructive c ...
