SHORAI EDGE

Overview and positioning

SHORAI EDGE holds the flagship position in Toshiba's Japanese residential lineup. It targets customers who prioritise technical performance and build quality over decorative features. Within the LeoKlima range it sits above SEIYA 2 — Toshiba's entry-level Japanese model with SEER 6.10 and A++ class — and alongside HAORI, which carries the same hybrid inverter platform but adds a removable linen-textured textile panel. SHORAI EDGE is the choice for buyers who want the top energy class and the best filtration in a neutral white casing, without a design premium.

Toshiba is a Japanese manufacturer with over seventy years in air conditioning. European operations run through Toshiba Carrier Corporation — a joint venture with Carrier Global — providing access to Japanese component engineering alongside a global service network. In Poland Toshiba maintains authorised service partners covering both warranty handling and access to genuine spare parts. LeoKlima holds authorised Toshiba installer and service status.

The 3.5 kW variant suits a typical living room of 25–35 m², a bedroom in a detached house or a private study. A+++ energy class in both cooling and heating means running costs stay at the lowest achievable level, despite the higher purchase price. Over a thousand hours of annual use, the efficiency gap between SHORAI EDGE and an A++ unit translates to tens of kilowatt-hours saved per year — a difference that progressively offsets the additional upfront cost over a multi-year operating horizon.

Cooling and heating technology

At the centre of the SHORAI EDGE refrigeration circuit sits a DC rotary compressor with Toshiba's integrated hybrid inverter. The inverter modulates output continuously — without the threshold-based switching of on/off systems. The full range of the series spans 2.0 to 7.0 kW in cooling and 2.5 to 8.0 kW in heating. For the 3.5 kW variant this means a constant, graduated power level matched to the room's actual demand at any given moment — steady temperatures and no abrupt current surges.

An external PMV (Pulse Modulating Valve) controls R32 refrigerant pressure and flow independently of outdoor load changes. Toshiba transferred this component from its commercial systems to the residential range — the result is stable output across variable weather and a degree of control precision that simpler inverter designs without PMV cannot deliver. R32 refrigerant carries a GWP of 675 and zero ozone depletion potential (ODP=0), complying with current European F-gas regulations.

SEER across the SHORAI EDGE series reaches 8.60 and SCOP reaches 5.10 — figures placing the unit in energy class A+++ for both cooling and heating. Toshiba SEIYA 2 in the same capacity class achieves SEER 6.10 (class A++). The outdoor unit operates from -15°C to +46°C in cooling mode and from -15°C to +24°C in heating mode. That range covers every month of the Polish climate — the unit delivers reliable heating output at negative outdoor temperatures and maintains full cooling performance during extreme summer heat.

Comfort and air quality

SHORAI EDGE manages airflow with HADA-Care technology, which keeps the supply air jet flat along the ceiling rather than directed downward at room occupants. Air travels along the ceiling surface, descends along the walls and mixes with room air before reaching the occupied zone. The effect is most pronounced in cooling mode, where standard units typically produce uncomfortable cold drafts at seated height. The horizontal louvre adjusts automatically or can be set manually from the remote.

Air filtration in SHORAI EDGE operates through the Toshiba Ultra Pure filter. This filter captures PM2.5 particles — contaminants smaller than 2.5 micrometres that pass through standard mesh filters and reach the lower respiratory tract. Toshiba rates capture efficiency at 94% on the first air pass. Beyond mechanical particle trapping, the filter neutralises viruses, bacteria, mould spores and airborne odours, making SHORAI EDGE a meaningful choice for households with allergy sufferers, young children or anyone managing air quality year-round.

The indoor unit heat exchanger carries a Magic Coil protective coating that reduces organic deposit accumulation on the evaporator surface. Uncoated copper gathers biological material faster, which degrades heat-exchange efficiency over time and creates the conditions for unpleasant odours when the unit starts up. Magic Coil extends the intervals between professional heat exchanger cleaning without replacing annual servicing. Comfort Sleep mode automatically adjusts operating parameters to follow the night cycle, gradually shifting the target temperature as sleeping hours progress.

Controls and Wi-Fi

SHORAI EDGE ships with a wireless infrared remote covering all operating modes: cooling, heating, dehumidification, ventilation and auto. The remote includes a built-in weekly timer for setting different schedules on each day of the week — practical for households with consistent daily routines. An optional wired controller is available for installations where a fixed wall panel is preferred, such as offices or rental properties.

The built-in Wi-Fi module — fitted inside the indoor unit casing — connects to the Toshiba Home AC Control app for Android and iOS. The app provides remote switching, mode selection, target temperature adjustment and real-time energy consumption monitoring. For an A+++ unit the consumption data gives a clear picture of actual operating costs per cycle, helping users understand how well the system is performing relative to its rated efficiency class. The weekly schedule in the app functions independently of the handheld remote.

Home AC Control integrates with Google Home and Amazon Alexa, enabling voice control. Toshiba has certified SHORAI EDGE in both compatibility programmes. For smart-home users the unit can participate in automation sequences — switching on as part of a morning routine or turning off when the front door locks. Voice temperature control is useful when the remote is in another room or hands are occupied in the kitchen.

Design and build

The SHORAI EDGE indoor unit presents a clean white matte face without decorative elements — consistent with the Japanese design philosophy of precise, uncluttered form. The shallow profile keeps the unit close to the wall; in a neutral interior it recedes rather than dominates. The sharp edges referenced in the model name reflect precisely finished casing lines — distinct from the rounded plastic shapes of budget units. White finish aligns with standard Polish residential interiors and pairs with any interior colour scheme.

The outdoor unit is constructed from powder-coated galvanised steel, providing durability through years of Polish climate exposure — frost, rain, humidity and direct sun. The DC rotary compressor sits inside a sound-dampened enclosure within the casing, reducing structural vibration transferred to the building wall and limiting noise audible in rooms adjacent to the external mounting surface. The operating range of -15°C to +46°C in cooling and -15°C to +24°C in heating means no month in Poland falls outside the unit's operational parameters.

SHORAI EDGE is available in seven capacity variants, allowing precise sizing without over-specification. The 3.5 kW variant covers rooms of 25–40 m² depending on building insulation quality. Pipe connections use standard 1/4" and 3/8" copper, ensuring compatibility with any service provider and no dependency on proprietary components for future maintenance or relocation work.

Installation and service

The 8,847.30 PLN price with installation covers a complete system fit: outdoor unit mounted on the building wall or an anti-vibration base up to 5 metres of pipe run from the indoor unit, copper pipes in premium insulation (Armacell or Ebrille), gravity condensate drainage to the sanitary stack or through the wall to the exterior, electrical connection to the existing circuit, nitrogen pressure test and vacuum evacuation. After commissioning the customer receives a technical report with pressure-test parameters and refrigerant charge confirmation.

Before each installation a LeoKlima technician visits the site at no charge to assess wall layout and pipe-routing options — decisions that determine the final aesthetic result. Routes can be run flush to the wall (requiring limited masonry work), in PVC trunking or on the surface with minimal structural intervention. Each approach is discussed with the customer before work begins. Anti-vibration brackets for the outdoor unit are standard in every LeoKlima installation, reducing vibration transferred to the building and protecting the compressor.

Manufacturer warranty covers two years on components, with extended compressor protection available through product registration on the Toshiba platform. LeoKlima as an authorised Toshiba installer provides the complete installation documentation required for any warranty claim. Service in Warsaw and surrounding areas is performed by F-gas certified technicians. In-season response time (June through August) is up to 48 hours from the report; outside the season typically 24 hours. Annual servicing — cleaning the Ultra Pure filter, checking refrigerant pressure and inspecting the Magic Coil heat exchanger — sustains full performance across many seasons.

Who this model is for — summary

Toshiba SHORAI EDGE 3.5 kW suits customers who want the best available Japanese technology in a standard white casing — with no compromises on energy efficiency, air quality or operational temperature range. It is the model for buyers who understand that A+++ class generates real electricity savings over multi-year use, and who want confidence that the unit will function reliably at -10°C outdoors in January with the same dependability it delivers in July.

At 8,847.30 PLN with installation, SHORAI EDGE occupies the Japanese premium tier — priced at the level of Mitsubishi MUZ-AY and substantially above A++ units from Chinese manufacturers. Customers working with a tighter budget will find solid A++ models in the LeoKlima range starting below 5,000 PLN with installation. Customers for whom wall appearance matters as much as efficiency can consider Toshiba HAORI with its removable textile panel. SHORAI EDGE is chosen by those who want maximum performance in a clean white casing.

The Ultra Pure filter's capacity to neutralise PM2.5, viruses and bacteria makes SHORAI EDGE a strong fit for families with young children, allergy sufferers sensitive to pollen or dust mites and Warsaw residents who rely on the air conditioner as a primary tool for indoor air quality during the pollen season. Noise levels in quiet mode below a whisper allow the unit to run overnight in the bedroom without disturbing sleep.

The most productive first step before purchase is booking a free site survey — a LeoKlima specialist assesses the room's thermal characteristics, checks pipe-routing possibilities and identifies the best placement for the outdoor unit. Contact via the form on the site or by phone on 502 010 010. Customers with technical questions about comparing SHORAI EDGE with other models are welcome to speak with an adviser — the conversation typically takes a few minutes and leads to a well-informed decision at no cost.

Long-term reliability depends on installation quality as much as on the unit's specification. Inadequate vacuum evacuation or skipped pressure testing shortens compressor life even in the best-engineered equipment. The technical handover report that LeoKlima provides after every installation confirms that the work was completed to standard and serves as the foundation for any future warranty claim.
