Eco Sun's manufacturers core technology is a proprietary hybrid aluminum thin ﬁlm. The original version was developed nearly 20 years ago. It is a mature and reliable element which has been updated a number of homes as newer manufacturing technologies became available; it is the oldest ﬁeld‐proven far‐infrared heating technology in existence.
The thin‐ﬁlm heating element is constructed using a combination “printing‐press” and “printed circuit‐board technology”. After the desired pattern has been etched, the element is encapsulated by an ultra‐thin Mylar insulator. This process allowed us to create a ﬁlm that optimizes the heat transfer to the radiating surface and to distribute it evenly across this surface, creating a near‐perfect radiated pattern (most competitor’s prod‐ucts only radiate from a small circle, or ”hot spot” in the center; making these very ineﬃcient when compared with Prestyl’s technology).
Environmentally responsible — The housing and ﬂoating radiating surface are made of high‐grade fully recyclable Aluminum to match the thin‐ﬁlm’s expansion characteristics. Using nearly identical materials minimizes internal stresses and the result is a much longer life‐expectancy than competitors’ panels have.
We use a fully recyclable hypoallergenic insulation material which has been approved for use in hospital operating rooms.
How do our designs compare with competitors’ products? To answer this we need to look at the history of (far) infrared….
(Far) Infrared history
The ﬁrst Far IR systems were resistor wires coiled up in the ceilings. These provided a comfortable heat and yielded dramatically reduced energy consumption. Because of the corrosion associated with the constant warming up and cooling oﬀ, the life expectancy was relatively short and repairs meant tearing out the ceilings to gain access.
After this there were a few manufacturers that built far‐infrared heating panels using this same technology. These worked very well but required routine (sometimes expensive) replacements of the heating elements. The advantage was that these would simply be removed, repaired and reinstalled.
Today there are still a few manufacturers, several in the USA, using this technology; the coils have been replaced with a thin resistive wire that is sandwiched between some sort of heat distributing foil. The advantage is a cheap unit (rivaling carbon) but one that has the same short life expectancy as the older systems.
Regardless of the quality of the resistive wire, these units are prone to failure since these have a very poor “element to surface ratio”. The thinner the wire the “hotter” it needs to run in order to conduct its heat to the far‐infrared radiating surface (images explaining these observations can be found below).
Over the years some manufacturers have tried using a very thin solid ceramic or other similar material to improve surface area, but there are several problems associated with these;
One — The surface will not heat evenly so there is repeated stress as these heat and cool so these generally crack and fail in a matter of one to three years,
Two — Due to the construction constraints of these panels it is impossible to evenly distribute the infrared energy, creating a “hot spot” in the middle of the panel.
Three — There is no way to compensate for dissimilar materials (expansion ratios of the element and front surface are diﬀerent and damage occurs)
Four — The ﬁlm inside of these substrates would be so thin that it could well be damaged in handling before it is even installed.
