Tubular Heaters
Tubular heaters provide gentle, low-level heat and are ideal for protecting small or enclosed spaces against frost, damp and condensation. Their slim design makes them particularly useful in garages, sheds, greenhouses, workshops, utility rooms and other areas where space may be limited.
For greater control, tubular heaters with thermostats can help maintain a more consistent temperature without providing more heat than you need. This makes them a practical and economical choice for background heating and frost protection.
Tubular heaters can be mounted on a wall or close to floor level, depending on the model and installation requirements. Protective guards are also available for suitable models, helping to prevent accidental contact with the heater.
Frost Watchers
Frost watchers are compact heaters designed to help protect cold spaces when temperatures fall. They are a useful choice for garages, sheds, workshops, utility rooms and other areas that do not have conventional heating.
A frost watcher heater provides low-level background warmth to help reduce the risk of frost and keep the surrounding temperature above freezing. Their compact size also makes them a convenient option where a larger electric heater would be unnecessary.
If you only need enough heat to protect a space, equipment or stored items during cold weather, a frost watcher can provide a simple and cost-effective solution.
