HEATSTRIP® Max Black Electric Heater – 3600 W
Powerful radiant heat with premium black design, ideal for demanding indoor and outdoor environments.
The HEATSTRIP® Max Black is a premium electric heater combining thermal performance and elegance. Designed for permanent use in residential or professional spaces, it delivers instant radiant heat while blending harmoniously into all kinds of environments thanks to its matte black finish and refined hexagonal grille. Within the hierarchy of the Max Black range, the 3600W occupies the position of absolute flagship model — more powerful, longer, subject to more intense thermal stress during each operating cycle, and therefore more demanding of every component that makes it up. The choice of Incoloy 840, the reinforced hexagonal grille and the IP55 certification is not simply a carry-over of the 2400W specifications at a higher power level: it is a dimensioned response to qualitatively different requirements, those generated by a 3600-watt appliance in permanent operation on a professional installation.
Equipped with Incoloy 840 heating elements, an ultra-resistant alloy used in extreme industrial environments such as offshore oil platforms, the HEATSTRIP® Max Black offers exceptional durability, including in difficult outdoor conditions. Its soft-glow technology guarantees comfortable heat with very low light output, perfect for preserving the atmosphere of a welcoming space. The relevance of Incoloy 840 is even more evident at 3600 watts than at 2400 watts: the temperature reached by the heating element in operation is proportionally higher, the expansion-contraction cycles at each switch-on and switch-off are greater, and the cumulative mechanical stress over the life of the appliance is more intense. Incoloy 840, with its optimised nickel and chromium content specifically formulated for resistance to high-temperature oxidation, is one of the few alloys capable of maintaining its mechanical and electrical properties under these conditions over several tens of thousands of cycles.
With its IP55 protection rating, it is fully weatherproof against rain and dust. It is designed, developed and assembled in Australia, reflecting recognised expertise in outdoor heating. The IP55 certification of the Max Black 3600W deserves particular attention in view of the power of the appliance. Integrating IP55 protection into a 3600-watt unit implies specific design choices around seals, cable entries, electrical connectors and housing ventilation — all areas where waterproofing constraints and high-power thermal constraints come into tension and must be resolved simultaneously. The fact that the appliance is IP55 certified at 3600 watts is proof that these tensions have been successfully resolved, and that watertightness is maintained even under prolonged full-power operation.
Key strengths
- Immediate radiant heat: directly heats people and objects. At 3600 watts, the thermal power rise perceived by occupants is measurable within a few seconds — well before the ambient air temperature has had time to react. This immediacy is particularly valuable in venues with a high table turnover where a heated terrace must be ready to welcome new guests just minutes after the previous ones have left, without long preheating times that would hinder service.
- Soft-glow technology: low brightness for a preserved atmosphere. On a 3600-watt appliance, controlling the emitted light spectrum is proportionally more important than on less powerful models. The soft-glow technology of the Max Black 3600W ensures that the 3600 watts of power are translated into perceived heat and not perceived light — the discreet orange halo indicating that the unit is operating remains at the same intensity as on the 2400W model, without increasing with power. It is an achievement in spectral management that preserves the atmosphere of dining and reception spaces even at full power.
- Elegant black finish: ideal for high-end establishments, hotels, restaurants and design terraces. The hexagonal grille of the Max Black 3600W presents, over the 118 cm format, a repetition of the hexagonal motif on a surface 39% larger than the 2400W model, creating a broader geometric composition that further asserts the visual presence of the appliance. Installed on the ceiling of a large terrace or hotel hall, the Max Black 3600W appears as an architectural statement piece — a long black panel structured by its hexagonal geometry — that the eye identifies as a quality object even before associating it with its heating function.
- Robust construction: Incoloy 840 heating elements and anti-corrosion structure. The total corrosion resistance mentioned in the technical specifications is a systemic property of the appliance, not just of its heating element. The anodised aluminium housing, stainless steel screws, sealed cable-entry gaskets and mounting brackets have each been selected for their specific resistance to corrosive agents — salt, chlorine, atmospheric acids — that characterise the most demanding outdoor environments. The sum of these material choices produces an appliance in which no component is the weak link in its overall durability.
- Permanent installation: indoor or outdoor use all year round. The requirement for installation by an approved technician for this model is directly linked to its nominal power and the electrical requirements that follow from it. A 3600-watt appliance requires a professional check of the supply circuit, cable cross-section, protective breaker rating and earthing quality — factors that only a qualified electrician can ensure are compliant with standards. Far from being a constraint, this requirement is a guarantee of safety and compliance that protects the user, validates the manufacturer’s warranty and ensures that the installation will function as intended throughout its lifetime.
- Australian design: certified quality, longevity and efficiency. The Max Black 3600W is the most complete demonstration of Australian expertise in this catalogue: the most powerful product, the most technically demanding, and the one that pushes every material and design choice the furthest. That it is developed and assembled in Australia is not a generic origin claim — it is recognition that the standards governing its design are those of a market where year-round outdoor thermal performance is a domestic necessity, not a seasonal luxury.

The dual 4-year residential / 2-year professional warranty of the Max Black 3600W — identical to that of the 2400W model — is a strong signal of the manufacturer’s confidence in the durability of Incoloy 840 even at the maximum output of the range. HEATSTRIP commits to 4 years under residential use conditions for a 3600-watt appliance in permanent outdoor installation: this is a durability promise that very few high-power heater manufacturers are willing to formulate with such clarity. For architects, project managers and engineering consultants who integrate the Max Black 3600W into their projects, this warranty is the final argument that turns a technical choice into certainty of lasting performance.

Chaleur immédiate, rendu premium
Reçu rapidement et très bien emballé. La finition noire est superbe et la chaleur se ressent en quelques instants. La faible lueur est un vrai plus : on garde une ambiance agréable, sans effet “lampe rouge”.

Elegante e potente
Ottimo impatto estetico: nero opaco molto raffinato. Riscalda subito e non rovina l’atmosfera perché la luminosità è minima.
