Heating device
Heating equipment to combat frost in winegrowing includes various types of equipment: vine heaters and heat generators to spread intense heat over large areas, mobile burners for rapid intervention, and infrared tubes or electric heating cables for gentle, long-lasting protection. Each solution can be adapted to the specific needs of the farm, offering flexibility and efficiency depending on the size and exposure of the plots.
Infrared tubes
This
technology uses infrared tubes placed along the rows of vines to emit radiation that heats the buds directly, without having to heat the surrounding air. Thanks to temperature sensors, the system is automatically activated as soon as the set threshold is reached. This system is an alternative to traditional methods of combating frost, offering a good compromise between efficiency, the environment and ease of use.
Howit works: infrared tubes attached directly to the rods emit light that heats the buds directly. The system is triggered automatically by temperature sensors.
Advantages : less sensitive to wind, no need to heat all the surrounding air (reduced heat loss), more targeted operation on buds.
Energyconsumption: depends on the type and length of tubes, and the power required. To cover a hectare, power in the order of tens of kilowatts may be required (e.g. a generator of ~ 80 kW for 1 ha in some cases).
Installation : seasonal installation of the infrared tubes in the vines, attachment to the support rods or cables, use of biodegradable tapes/clips for temporary attachment. Power supply via mains connection if nearby or generator.

Heating cables

These
They
electrical heating systems limit the drop in temperature close to the buds.
They
are positioned at the bending wire, close to the rod. The range of protection is approximately 10 cm. The cables are connected to an electrical cabinet. Installation costs are high, but the system is robust and long-lasting.
How it works: these heating cables are laid directly on the vines or in the rows and spread heat by conduction. They can be triggered automatically or manually.
Advantages : discreet solution with an efficiency of around -5 to -7°C.
Energyconsumption: around 80W per metre of cable. Requires mains power supply if nearby or generator.

Warm air emitting system combined with a blower
Several
types of equipment fall into this category
- :
- a fixed system (on a concrete slab) with a rotating fan that emits hot air from fossil fuels
- a mobile system, associated with a fan that emits hot air using fossil fuel, electricity or wood pellets
- towed system, emitting warm air using fossil fuels
- Operating
Powersupply : Generally run on gas, fossil fuels or electricity.
Advantages: Cover larger areas and can be particularly effective in severe frost conditions.
and characteristics: Models vary in terms of thermal output and autonomy, with some providing thermal coverage for several hours.

Heaters
in operation - Garrigue R
How
it works: These devices generate gentle heat that spreads along the rows of vines, preventing temperatures from dropping below the critical threshold for the buds.
Fuels : Often run on gas, oil or wood, with models allowing the use of renewable fuels.
Advantages : They provide continuous heat and are suitable for medium to large-sized vines.
TechnicalFuels : Often run on gas, oil or wood, with models allowing the use of renewable fuels.
Advantages : They provide continuous heat and are suitable for medium to large-sized vines.
features: Some models can cover several dozen metres with an autonomy of 8 to 10 hours
Mobile
|burners||It
runs on wood pellets and replaces an oil-fired boiler. It is mobile and is used in conjunction with an air circulation system.How
it works: These mobile devices spread heat around the vines by burning fuel.
Advantages
Advantages
: Ideal for one-off jobs or for operations requiring rapid, targeted protection.
Technicalfeatures: The burners are mounted on wheels for easy movement and can cover an adjustable perimeter with a radius of 3 to 8 metres.
