Sorrento Double Commercial Infrared Heater - Weatherproof 3-4kW Outdoor Heater

Tansun Sorrento Double Infrared Heater

Powerful commercial-grade infrared heating for large outdoor and industrial spaces.

The Tansun Sorrento Double is a premium, UK-manufactured infrared heater designed to deliver high-intensity shortwave radiant heat across large areas. Engineered with a lightweight yet durable aluminium extrusion body, it features dual high-performance infrared lamps that provide powerful, targeted warmth exactly where it is needed.

Unlike gas heaters, the Sorrento Double heats people and surfaces directly rather than the surrounding air. This makes it highly effective in outdoor and exposed environments, even where wind and airflow would reduce the performance of traditional heating systems.

Designed for Large Commercial Spaces

The Sorrento Double is ideal for environments where strong, directional heat is required across wide or open areas.

• Pub gardens and outdoor hospitality terraces
• Stadiums and sports venues
• Smoking areas and transport hubs
• Warehouses, workshops and industrial units
• Large covered outdoor spaces

FAQ's

Is the Sorrento Double suitable for fully exposed outdoor areas?

Yes. Its shortwave infrared technology is specifically designed to perform well in exposed and windy environments.

What size area can it heat?

Coverage depends on mounting height and layout, but it is designed for medium to large outdoor zones and commercial spaces.

Can multiple heaters be used together?

Yes. The Sorrento Double is often used in grouped configurations to create a scalable heating system.

Is it better than gas patio heaters?

In most outdoor settings, yes. Infrared heaters are more efficient as they heat people directly rather than wasting energy heating the air.

Does it require maintenance?

Minimal maintenance is required. The heater contains long-life lamps and no moving parts.

How much area does the Sorrento Double actually cover?
The Sorrento Double (3.0kW–4.0kW) provides an impressive heat coverage of up to 26–30 square metres. Its wide-beam parabolic reflector is specifically designed to project heat over large commercial spaces like terraces and warehouse work zones.

Is it fully waterproof for permanent outdoor installation?
Yes. It features an IP-rated weatherproof design. The body is constructed from high-quality aluminium extrusion with a powder coating that prevents rusting, making it suitable for year-round outdoor use even in exposed locations.

What are the minimum safety distances for mounting?
To ensure safety and optimal performance, the following minimum clearances are required:
From Floor: 3.0m (3.0kW model) or 3.5m (4.0kW model).
From Ceiling: 0.5m.
From Side Walls: 1.0m.
From Combustibles: Maintain at least 1.8m from the front of the heater.

How much does it cost to run per hour?
Running costs depend on your local electricity tariff. For example, a 3.0kW unit used at 100% power for one hour consumes 3 units (kWh) of electricity. Using a Tansun Dimmer Controller can reduce costs by up to 50% by lowering the heat output when less intensity is needed.

Does it require a special electrical setup?
While it runs on a standard 230V supply, the Sorrento Double (especially the 4.0kW version) draws significant current. It is strongly recommended to use a qualified electrician for installation and to ensure your circuit uses a Type 3 (Type C) MCB to handle the initial "inrush" current of infrared lamps.

Can I control multiple heaters with one remote?
Yes. By using an optional Tansun 6.5kW Receiver, you can use a single 6-channel remote to control up to six individual heaters or zones, including dimming functions.

How long do the infrared lamps last?
The high-quality quartz lamps have an average lifespan of approximately 7,000 hours. Using a "soft start" controller can further extend this life by up to 20% by reducing electrical stress during startup.

Can it be mounted at an angle or on a ceiling?
Yes. The included brackets allow for horizontal or angled mounting. It can also be suspended from a ceiling using chains, provided the minimum 0.5m clearance from the ceiling is maintained.

Does it emit a bright red light?
As a shortwave infrared heater, it does emit a warm glow. For environments where no light is preferred (like theaters or specific restaurant moods), the Sorrento Ceramic Double is the "no-glare" alternative, though it takes longer to heat up.

What maintenance is required?
These units are virtually maintenance-free. Unlike gas heaters, they require no annual safety servicing. Owners simply need to ensure the unit is switched off and cool before occasionally wiping the body and reflector with a soft, dry cloth to remove dust.
