Yes, curtain heaters are designed to reduce energy loss by maintaining a separation between indoor and outdoor environments. This helps minimize the need for additional heating or cooling, making them energy-efficient, especially in commercial and industrial settings.

Curtain heaters need minimal maintenance, but it’s recommended to clean the air filters and check for any blockages regularly to ensure optimal performance. Servicing them annually by a professional is also advisable for long-term efficiency.

Yes, curtain heaters are versatile and suitable for a range of applications, from small shops and offices to larger commercial buildings, warehouses, and industrial settings. They are particularly beneficial for high-traffic entrances.

The running cost of a curtain heater depends on its size, power, and usage. However, by reducing the loss of heated air in the winter and cooled air in the summer, they can lower energy bills and be cost-effective over time.
