How to choose the right overdoor heater

An overdoor heater works as an air curtain: a fan draws air in, passes it over a heating element and directs it down across the opening. The stream of air reduces the exchange of warm inside air with cold outside air, so the rest of the heating system does not have to work as hard each time the door opens.

Overdoor and downflow heaters

Over door units such as the ATC 3kW model are designed for entrances, mounted horizontally above the frame. Downflow heaters like the ATC Bavaro are wall-mounted fan heaters intended for rooms such as bathrooms and cloakrooms, where quick, directed heat is useful. Choose the format that matches where the heat is needed, not just the wattage.

What to check before ordering

Door width: the unit should cover as much of the opening as possible to avoid cold gaps at the sides.
Mounting height: keep within the maximum height the manufacturer quotes, as the air stream weakens with distance.
Controls: a remote or thermostat lets staff adjust output without climbing up to the unit.
Supply: a 3kW heater draws roughly 13A, so plan the circuit and protection accordingly.
Location rating: for bathrooms, confirm the IP rating and permitted zones in the instructions.

Installation tips

Overdoor heaters are usually hard-wired, so allow for a suitable isolation point and size the twin and earth cable for the load and installation method. Many installers protect heater circuits with an RCBO; check current wiring regulations and the manufacturer's instructions for the exact requirements. For room heating in wet areas, compare these units with our bathroom heaters.
