How They Work and Technology

How do TANSUN infrared heaters work?

TANSUN infrared heaters use proven short-wave infrared technology. Unlike conventional heaters, they do not heat the air; instead, they heat surfaces and people directly through infrared radiation. This provides instant heat without a preheating period and is particularly efficient for outdoor areas or poorly insulated spaces.

What is the difference between short-wave and long-wave infrared?

Infrared radiation is divided into three categories:

IR-A (short-wave infrared, 0.78-1.4 μm): TANSUN uses this highly efficient technology. IR-A offers the highest radiation intensity and the best penetration through the air. This makes it ideal for outdoor areas and poorly insulated spaces. The heat effect is immediate, without a preheating period.

IR-B (medium-wave infrared, 1.4-3 μm): Medium radiation intensity, suitable for partially insulated areas with a moderate heating-up time.

IR-C (long-wave infrared, 3-1000 μm): Lower surface temperature and more suitable for well-insulated indoor spaces, but requires longer heating-up times.

TANSUN relies on IR-A short-wave technology for maximum efficiency and an immediate heating effect.

Applications

Which areas are TANSUN infrared heaters suitable for?

TANSUN infrared heaters are versatile and suitable for both commercial and private applications. They are particularly effective in workshops, halls, on patios, in sports halls, churches and many other areas where fast, targeted heating is required.

Costs and Cost-effectiveness

How much does it cost to operate TANSUN infrared heaters?

Operating costs depend on your electricity rate and usage duration. Here are some examples based on an electricity rate of €0.30/kWh:

• 1.5 kW infrared heater: €0.45 per hour at full power
• 2 kW infrared heater: €0.60 per hour at full power
• 3 kW infrared heater: €0.90 per hour at full power

Important: Thanks to direct heat transfer and demand-based use, actual costs are often significantly lower than those of conventional heaters.

How efficient are TANSUN infrared heaters?

TANSUN infrared heaters offer maximum energy efficiency. Almost 100% of the electrical energy is converted into heat, without losses through pipes or air circulation. By comparison, gas patio heaters lose 20-40% of their energy through exhaust gases.

Calculating the required output for halls and workshops

As a rule of thumb for the coldest winter days, the correct sizing of your infrared heater requires approximately 0.2 kW of heating output per square metre. The stated areas do not necessarily correspond to the total room size, as only parts of a space are often heated. Example: A 2 kW heater can heat approximately 10 m² of working area in a 100 m² hall. During the transitional season, the required output is correspondingly lower.

Installation and Mounting

How are TANSUN infrared heaters installed?

Installation is simple and flexible. Only a power connection is required—no gas or exhaust lines. The heaters can be mounted on both walls and ceilings and are suitable for new and existing buildings. Professional installation by an electrician is recommended.

What control options are available?

TANSUN offers various control options: manual on/off switches, dimmers for infinitely variable output control, thermostats for automatic temperature control, timers for programmed operation, remote controls and motion sensors for automatic activation.

Safety and Maintenance

Are TANSUN infrared heaters safe?

TANSUN infrared heaters meet the highest safety standards, with CE marking and compliance with German safety standards. Protective grilles prevent direct contact with hot surfaces, and overheating protection is integrated into all models. Various IP protection ratings enable use outdoors and in damp areas. Unlike gas patio heaters, they produce no combustion gases or open flames.

What maintenance do TANSUN infrared heaters require?

TANSUN infrared heaters require little maintenance. All that is needed is regular cleaning of the reflectors for optimum performance, visual inspection of the protective grilles and mountings, and inspection of the electrical connections by a qualified professional. As there are no moving parts, wear is minimal.

How long do TANSUN infrared heaters last?

TANSUN stands for durability and quality. With over 40 years of experience in infrared technology, high-quality "Made in UK" materials and robust construction for continuous operation, TANSUN offers a comprehensive manufacturer’s warranty. More than 500,000 heaters have already been sold worldwide.

Frequently Asked Questions

Can TANSUN infrared heaters also cool?

TANSUN infrared heaters are primarily designed for heating. However, for cooling applications in industrial environments, we also offer evaporative coolers, which are an efficient addition, particularly during the summer months.

Are TANSUN heaters suitable for year-round use?

Yes, TANSUN infrared heaters are designed for year-round use. The main season is between October and December, but they also operate efficiently during the transitional season with reduced output requirements.

What payment methods are available?

We offer flexible payment options: PayPal, Klarna, Apple Pay, Google Pay, credit cards (Visa, Mastercard, American Express) and other options such as EPS, Maestro, Union Pay and Shop Pay. Credit-checked business customers can also purchase on account.
