Compact Heating for the Tightest Spaces
The AUTOTERM Air 2kW Tight Space is the heater built for the installs that defeat a standard unit. Its shortened, adjustable outlet casing lets you mount it in confined cabinets, under seats, and in bulkhead recesses where a straight air-pipe run simply isn't possible — without forcing a sharp bend that kills airflow and triggers overheating shutdowns.
Same proven 2kW diesel performance as the standard Air 2D, packaged to fit where it couldn't before.
Why the Tight Space version?
Rotatable directional air outlet — exits forward, sideways, or angled to suit your install
Shortened casing removes the clearance requirement that rules out a standard heater
No sharp duct bends at the outlet means full airflow, no overheating, no error codes
Handles UK winters and high-altitude mountain trips — rated to -45°C and 4,200m
Low power draw (10–29W) keeps your leisure battery happy overnight
