Product Overview

Dimplex AC over door heaters provide multi-directional, powerful and effective heating above the entrance to shops, offices and almost any small doorway.

When fitted above an open door, the warm airflow encourages trade by allowing doors and entrances to remain ‘open for business’ in many commercial applications.However, over door heaters are also ideal for any situation where a high-level fan heater is required and so they can be used anywhere in your premise where powerful, energy-efficient heating is required.

Offered at the best VAT-inclusive price on the Web (and with a Price Match Guarantee in the unlikely event that you find it cheaper). 

This model, the Dimplex AC3RN, is designed for a single doorway (for double doorways please see the AC6N) and offers an adjustable airflow, full-heat, half-heat and fan-only settings. It also arrives with an infra-red handheld remote control for extra convenience.
This makes it particularly suitable for any installation where you need to control exactly when the heater operates

The design is curved and modern and comes with a cream finish to fit unobtrusively in to commercial interiors. All units are manufactured in the British Isles - so you have the added satisfaction of Buying British.

What makes an air curtain from Dimplex particularly special, however, is its built-in energy saving features - helping to put you in control of ever-increasing energy costs.

These features include “Thermostat Regulation Mode” which is the most cost-effective way to save energy - switching heat in and out as conditions dictate without limiting performance.

You can also choose to run the air curtain in “Eco Mode” and link to your HVAC system and so save up to 97% of running costs. The Dimplex AC45N can also be linked to a PIR sensor or auto-door sensor and so save money by being used only when doors are opened.


Air curtains work by separating two different temperature zones with an invisible curtain of air. They provide a fast moving air stream to block air movement through the door whilst allowing the door to remain open.

Placing an air curtain above or to the side of the entrance covering the full door width maximises performance by stopping heated air escaping in winter, or cooled air escaping in summertime.
