WHY AIRDOOR > Cost Savings
Lower running costs and long‑term savings
AirDoor delivers significantly lower running costs than traditional overdoor heaters by operating with no heating or cooling element, while also reducing the operating cost of existing building HVAC systems by allowing them to work more efficiently.
How AirDoor delivers cost savings
Significantly lower running costs than overdoor heaters
Because AirDoor operates without any heating or cooling element, its ongoing running costs are significantly lower than traditional overdoor heaters. Rather than constantly generating heat at the entrance, AirDoor uses a smart control strategy and variable‑speed fans to consume only the energy required to counteract infiltration at any given moment.
In typical operation, AirDoor costs around £310 per year to run. By comparison, an 18kW electric overdoor heater, running for 2,300 hours per year at £0.23 per kWh, would cost approximately £10,000 per year to operate. This efficiency delivers a strong and predictable running‑cost advantage over the operating life of the system.
Reduces the operating cost of existing building systems
By limiting the loss of treated indoor air and reducing the volume of unconditioned air entering at the entrance, AirDoor lowers the load placed on existing heating and cooling systems. This allows the building systems to maintain target conditions without over‑working to compensate for repeated disruption at busy doorways.
With more stable conditions at the entrance, HVAC systems can operate more efficiently and predictably as part of normal building operation. Over time, this reduced demand helps lower operating costs across the building, without requiring changes to existing equipment.
One investment delivering long‑term financial returns
Based on direct operating cost comparisons with traditional overdoor heaters, AirDoor typically achieves a payback period of under 3.5 years. This calculation is based solely on product‑level running‑cost reductions and does not factor in additional savings from reduced heating and cooling demand on existing building systems.

Beyond payback, savings continue to accrue through significantly lower ongoing running costs. In new or refurbished buildings, effective entrance sealing can also support more efficient HVAC design, potentially reducing the size and cost of heating and cooling plant required.

Additional AirDoor benefits
Performance you can measure
Weather Protection
Active protection against wind, rain and unwanted outside air, delivering consistent comfort and efficiency right across the entrance while freeing up valuable space near the doorway.
Energy Efficiency
By limiting air infiltration at the entrance and retaining treated indoor air, AirDoor reduces energy loss and helps existing heating and cooling systems operate more efficiently.
Thermal Comfort
By maintaining consistent indoor temperatures and eliminating cold draughts at the entrance, AirDoor creates a more comfortable environment for customers, staff and visitors.
Indoor Air Quality
AirDoor limits the entry of dust, pollutants and insects at the entrance, supporting cleaner indoor air and healthier conditions for occupants.
Sustainability
By reducing energy consumption and carbon impact at the entrance, AirDoor helps businesses cut emissions and supports net-zero ambitions without compromising comfort or performance.
