Auxiliary Heating Accessories

For a suitable installation, a change of layout or more convenient controls: here you will find accessories and replacement components for your parking heater. Many of these parts are already included with our heaters and are also available separately. Add what your installation requires, replace existing components or upgrade your system to suit your needs.

Install, replace or upgrade: which accessories do you need?

This category includes additions for individual installations as well as parts for replacing components and upgrading existing systems. A control panel or fuel pump listed separately here does not mean that you need to order it in addition to a new heater.

Our Autoterm Air 2D, for example, already comes with a suitable extra-quiet fuel pump including its rubber mount, plus a control panel that you select when ordering. Basic components for the fuel supply, exhaust system and wiring are included too. Any additional materials depend on your vehicle, installation location and planned upgrades.

Under “Land Vehicles”, you will find accessories for camper vans and other vehicles, while “Yacht/Boat” covers components for marine installations. “Universal” includes parts for different applications. Regardless of the category, always check compatibility with your specific heater.

Brackets and mounting flanges: adapting the installation to your vehicle

The installation location and floor construction determine which mounting components you need. A suitable mounting flange can make it easier to install an air heater through an insulated vehicle floor. If you relocate an existing heater, a different bracket may be required.

Measure the full floor thickness to be bridged, including insulation and flooring. Also check the heater’s mounting pattern, the flange dimensions and the space available for connections and lines beneath the installation point.

Wall or angle brackets suit particular mounting arrangements. However, the shape of a bracket does not mean that the heater can operate in any orientation. Follow the permitted mounting positions and requirements for securing, sealing and heat clearances. If you have a complete heating installation kit, first check whether a suitable flange or bracket is already included.

Control panels: replacing existing controls or adding convenience

When buying an Autoterm Air 2D from us, you select your control panel as part of the order; it is then included with the heater. Separately available control panels are useful if you need to replace a damaged unit or want to switch to a different type of control later.

When upgrading, consider which features you are missing: different menu navigation, timers, a clearer display or an additional control point. Panels such as Comfort Control and Touch Control offer different approaches.

With compatible combinations, Push Control allows you to add a second control point, for example in the cab or beside the bed. Check compatibility with your heater and existing control panel, along with the connecting cables required. Not all controls can be combined.

Connection and extension cables: when the cable route gets longer

A control panel connection cable is already included with the Air 2D. An additional extension is only needed if your planned route exceeds the available length – for example, when mounting the panel on the opposite side of the vehicle or moving it later.

Distinguish between a longer replacement cable and an extension that plugs into the existing wiring. Check the connector type, pin count and intended connection point. Cables designed for different positions in the wiring are not interchangeable simply because their lengths match.

Measure the actual route, including bends and some extra length for connections, and observe the maximum permitted total length. If the control panel’s temperature sensor is used for room temperature regulation, choose a location that gives a representative reading, away from direct warm airflow or strong sunlight.

Fuel supply: suitable parts for replacement and modification

Our Air 2D already includes a suitable fuel pump – the extra-quiet version is part of the package too. A separately available pump may be needed as a replacement or for a compatible upgrade to an older installation.

When replacing a pump, the heater model, voltage and fuel delivery specification must match. A hose connection that fits is not enough. Check that the pump is specified for your heater and its 12 or 24 V version.

Parts for the fuel take-off and fuel line are also included with the heater. Depending on the vehicle, a specialised solution may still be useful, such as a fuel pick-up designed for the existing tank unit. Choose these additions according to the actual vehicle specification and intended connection.

Reducing noise: upgrading where it makes a difference

The Air 2D already includes an extra-quiet fuel pump and an exhaust silencer. If you want to reduce noise further, first identify its source: fuel pump ticking, heating-air noise and exhaust noise originate in different parts of the system.

An optional exhaust silencer such as the Supersilent can further reduce noise at the exhaust outlet. Purpose-designed heating-air silencers address airflow noise inside the vehicle. Suitable mounting and vibration isolation can also help prevent vibration from transferring to the bodywork or furniture.

For every addition, check suitability for your heater, connection diameter and the space required. Additional components must remain compatible with the permitted pipe lengths and flow resistance.

Adapting exhaust routing and heat protection

The Air 2D already comes with exhaust system components. Separately available exhaust pipes, silencers and insulation therefore also serve as replacements or allow adaptation to a different installation location. Special pass-through arrangements may require additional components.

Compare connection diameters, materials and permitted routing. Exhaust components are not interchangeable with heating-air or combustion-air components. Suitable exhaust pipe insulation can reduce heat transfer to the surroundings, but it does not replace the specified heat clearances.

After any modification, the exhaust outlet and condensate drainage must still comply with the installation requirements. Exhaust gases must not be able to enter the occupied space through windows, doors, ventilation openings or air intakes.

Boats and yachts: accessories for specific installation conditions

A marine installation may require different mounting and exhaust components from a land vehicle. A through-hull exhaust fitting, for example, must suit the exhaust diameter, hull construction and intended installation position.

Check that exhaust components are suitable for marine use and meet the requirements for gas-tightness, condensate drainage and protection against water ingress. A silencer intended for external mounting on a vehicle is not automatically suitable for installation inside a boat.

The “Yacht/Boat” subcategory helps you narrow down suitable components. Here too, compare the contents of your heater package or marine installation kit with your planned layout first.

Before buying: what do you already have, and what needs to change?

For a new installation, start with the contents of your chosen heater package or complete kit and add the materials needed for your vehicle. For an existing system, identify the specific task: do you need to replace a part, extend a cable route, change the controls or reduce noise?

You will find ducts, branches and outlets for distributing heat around the living space under air ducting. When replacing existing components, have the exact heater model and part number ready wherever possible.

Have these details ready when choosing

• Task: Is this a new installation, a replacement, a modification or a comfort upgrade?
• Heater: Which model and 12 or 24 V version do you have?
• Existing equipment: Which parts are already included or installed?
• Installation: Which floor thickness, mounting surfaces, cable routes and connection sizes need to be considered?
• Compatibility: Does the component suit both the heater and the parts you want to keep using?
