Why Opranic

Experience you can feel in the warmth

There are many companies that sell infrared heaters. Far fewer manufacture them. And only a handful have focused exclusively on infrared heating for more than seventeen years. Opranic entered the industry in 2009, initially as a distributor of other brands. Since 2015, we have designed and manufactured under our own name. This is the only category we operate in. And within that category, we go the extra mile to ensure the products meet our standards—not the factory’s.

The discipline

An industry since 2009, a brand since 2015

Experience in an industry is not the same as time spent in it. Seventeen years focused solely on infrared heating means we have seen the technology evolve, seen which designs age well and which do not, and seen which material choices actually withstand a full outdoor season in the Nordic climate. That kind of knowledge is not built in a quarter or through a product launch. It comes from solving the same problems again and again—each time with a little more information than the last.

Between 2009 and 2015, we worked as a distributor of other manufacturers’ products. That is where we learned what does not work. We saw warranty claims, we saw which components failed first, and we saw the difference between a heater that is cheap to manufacture and a heater that is inexpensive to own over time. That period was, in practice, our curriculum. When Opranic became its own brand in 2015, we already had a list of what we wanted to do differently. That list is still what we work from.

Ownership

OEM, not ODM: we own our own tooling

A large share of infrared heaters on the European market are ODM products. ODM stands for Original Design Manufacturer—a factory with its own catalogue shelf of ready-made designs. The retailer chooses a model, changes the colour, and adds its logo. The product is the factory’s design, not the retailer’s. It is a fast and inexpensive route to a product range, but it also means the seller cannot change anything fundamental. Not the housing material, not the reflector angle, not the control electronics.

Opranic operates according to the OEM model. We own the industrial design, we own the tooling, and we own the decisions about which materials are used. This means that when we are not satisfied with how a side reflector handles thermal expansion over time, we can change it. When we want the housing to be assembled with a specific type of stainless fastener instead of the factory’s standard solution, we can specify it. That freedom costs more per unit in manufacturing. It is also the reason the product looks the way it does—and lasts the way it does.

There are two ways to sell an infrared heater. One is to design it.

The System

A system, not an element

When people talk about infrared heaters, they usually talk only about the element. That is understandable, because the element is the visible, glowing part and the part that actually emits the radiation. But a good element is only one of five components that must work together for a heater to deliver comfort. The remaining components are at least as important, and they are often where the difference between a good and a less good product lies.

The parabolic reflector determines how the radiation is focused forward instead of being lost to the sides. The housing holds the entire construction together and determines whether the heater can withstand rain, wind, and temperature fluctuations without deforming. The side reflectors control how the radiation is distributed to the sides. The electronics keep the element temperature stable, which directly determines how long the element lasts. And then the element itself, which must operate at the right wavelength for the body to actually absorb the radiation. That physics is explained in detail in our article on how infrared heating works. On this page, it is enough to say that none of the parts is sufficient on its own.

Craftsmanship

Material choices you will not see in the specification

There are things you cannot learn from a product sheet. The specification says the housing is aluminium, but it does not say which alloy, how thick the material is where it matters, or how the surface is treated to withstand salt and moisture over ten outdoor seasons. It says the fasteners are stainless, but not which grade of stainless steel, and not how they are dimensioned for thermal expansion. It is in these kinds of details that a heater either ages well—or starts to look tired after two years.

We choose anodised aluminium instead of painted aluminium, because anodising is part of the material rather than a surface layer that can flake. We choose high-grade stainless steel, and in PRO V70 we go a step further with a grille in brushed 18/8 stainless steel with no surface coating at all, meaning there is no layer that can wear off. We specify fasteners and dimensions for thermal expansion, because an outdoor heater operates between summer heat and winter cold year after year. None of this is printed in large letters on the box. It is craftsmanship that only becomes visible after a few years—and then very clearly.

The design language

Minimalism is harder than it looks

Scandinavian design is neither unique nor secret. It is about restrained proportions, straight lines, and a general intention to let the product be calm in the room rather than draw attention to itself. It sounds simple, and that is precisely why it is difficult. When a heater consists only of a housing, a grille, and a mounted unit, every detail is visible. You cannot hide sloppy work behind decoration, because there is no decoration.

For a minimalist product to feel right, the details must actually be right. The joints between the housing and side reflector must be even, the material transitions must be considered, and the proportions must work both up close and at a distance. In practice, that level of control can only be achieved when you own your own industrial design, because decisions about form and material interfaces are not something you can order from a catalogue. That is one of the reasons Opranic works according to the OEM model rather than ODM. We do not believe a heater has to cost three or four times as much to look clean and well-proportioned. It should do its job, last for many seasons, and fit into the room. That is what we optimise for.

It is not the element that provides comfort. It is the system around the element.

Independent Research

LTU and Vattenfall: independent validation in Arctic Falls

In 2019, an independent thesis project was carried out at Luleå University of Technology, commissioned by the Research and Development department of Vattenfall AB. Vattenfall is one of Europe’s largest energy companies and operates a significant share of the Nordic region’s wind power. The study investigated whether infrared radiation can be used to de-ice wind turbine blades in Arctic conditions, and the tests were conducted in a climate hall at Arctic Falls’ facilities in Piteå, on a full-scale wind turbine blade weighing 87 kg. The heaters tested were Opranic’s then-current IR-X elements.

The results were clear. The combination the study concluded was most effective for de-icing across the entire blade was two IR-X heaters together with a supplementary halogen heater, placed at a distance of 1.5 m. In that configuration, an area measuring 2 × 1.2 m was melted free of ice. The study also noted that infrared radiation has a broader heat distribution than traditional de-icing systems, which is one of the technology’s fundamental advantages. For Opranic, the conclusion is as important as the research results themselves: an independent university, on behalf of an independent research commissioner, arrived at the same wavelength choice and the same system approach that our products have been based on since 2009. The IR-X element tested in 2019 has since been further developed into today’s IR-X Carbon Black, built on the same core principle but with improved power density and service life.

The market’s quiet endorsement

Why Opranic is the choice for professional wholesalers

There is one kind of marketing every brand can do itself: saying it is good. There is another kind of marketing you cannot buy: when someone else chooses to stock your products even though they can choose from the entire market. Sweden’s leading professional electrical and plumbing wholesalers stock Opranic. This includes the suppliers that electricians and installers visit every day to pick up materials for their projects.

It is a channel not driven by advertising or price alone. Wholesalers listen to their customers, and those customers are professionals who come back with warranty claims if the product does not last. A brand remaining in their range year after year is not a commercial claim, but a consequence of the product actually working in the field. It is an endorsement that does not show up in marketing and that we cannot write ourselves into. That is why we believe it matters.

Understand the technology behind the choice

This page has been about Opranic as a company: how we work, why we own our own design, which material choices underpin the products, and which independent research has validated the technical principles we build on. It has not been about infrared heating as a technology or the physics behind it, because that would make the page twice as long and would also repeat what we have already written elsewhere.

For those who want to understand the technology itself, there are three pages that go together with this one. What is infrared heating covers the basics: the sunshine principle, the three methods of heat transfer, and why infrared radiation is the only one that works outdoors. How infrared heating works goes deeper into the physics: wavelengths, why 2.4 micrometres is the optimal wavelength for comfort heating, skin absorption, and safety according to ICNIRP. And infrared heating outdoors applies the physics to the specific outdoor environment: the effect of wind on convection, power requirements per square metre, and season extension in the Nordic climate. Together with this page, the four articles form the foundation we believe a buyer should have before making a decision. Once that is in place, choosing the right product is straightforward.
