Vineyards and horticulture

Heating cables along the vine wire protect buds from spring frost. Also used for propagation beds and greenhouse soil warming.

Late spring frosts, just as buds open, are one of the biggest risks for vine growers. Heating cables along the vine wire protect the buds with an energy-efficient alternative to frost fans, sprinklers and candles.

Benefits and advantages

Unheated vines can lose up to 50% of inflorescence; heated vines reduce losses to about 13–20%
Energy efficient, with no direct CO₂ emissions
Proven savings compared with frost fans, sprinklers and candles
Easy, fast and reliable installation
Tough sheath resistant to weather, UV and chemical fertilisers
High pulling strength for tractors travelling along the rows

System design starting points

Heating cable fixed along the vine wire in each row
Customised to the vineyard area and number of rows, with accurate power design
For spring frost protection while buds are growing, not winter use
5 or 20-year warranty depending on the cable

System performance depends on design, installation and site conditions. Talk to us before you order so the output, layout and controls suit your project.

Other applications

Indoor

Under-tile floor heating

Thin heating mats or cables set in tile adhesive directly under the tiles. Fast to warm up, ideal for bathrooms, ensuites and kitchens in new builds and renovations.

Indoor

In-screed and in-slab heating

Heating cable laid in a sand-cement screed or concrete slab. The mass stores heat and releases it evenly, which suits whole-home heating and open-plan spaces.

Indoor

Timber and floating floors

A dry system with no screed. Aluminium-topped plates spread heat from a low-output cable under floating timber, laminate or engineered boards.

Outdoor

Snow and ice melting

Heating cables in driveways, ramps, stairs and paths keep surfaces clear of ice and snow. Sensors switch the system on only when it's cold and wet.

Outdoor

Roof and gutter de-icing

Cables in gutters, valleys and downpipes stop ice dams and icicles forming, protecting the roof, gutters and people below.

Frost

Pipe frost protection

Self-limiting cable fixed along water pipes and under insulation stops them freezing and bursting in exposed or unheated locations.

Commercial

Hot water temperature maintenance

Keeps hot water pipes at temperature so hot water arrives quickly at every outlet, reducing water waste in large buildings.

Commercial

Cold storage frost-heave protection

Low-output cable under freezer and cool-room floors keeps the ground beneath above freezing, preventing frost heave that cracks and lifts slabs.

Commercial

Sports field heating

Cables laid below the turf keep the root zone and surface free of frost so pitches stay playable through winter.

Agriculture

Agriculture and livestock

Heating cables in soil, seed beds and animal floors protect crops, seedlings and livestock from frost and cold stress.
