All guides · Diesel heating
I want to have the entire installation on a list before I choose a package. A heater with a mounting kit is only complete for your boat when the contents of the kit match the location, hose lengths, and the rooms you want to heat.
Start with a drawing of the boat
Mark the position of the heater, the diesel tank, the battery, and the desired air outlets. Then draw the potential duct routes. Use the actual lengths around bulkheads and cabinets; the distance in a straight line does not tell you how much hose or cable the installation requires.
Also note how the heater can be accessed for service. A location might look obvious until a bench or tank blocks the path to dismantling a component.
Divide the shopping list into six parts
| Part of the solution | What needs to be clarified |
|---|---|
| Heater and mounting | Model, voltage, mounting location, and suitable marine brackets. |
| Hot air | Hoses, distributors, outlets, return or intake air, and potential noise reduction. |
| Diesel | Tank connection, fuel line, metering pump, and placement. |
| Combustion air and exhaust | Separate routing, suitable marine components, thru-hull fitting, and heat/water protection. |
| Power | 12 or 24 V, wiring harness, fuse, and voltage drop during startup. |
| Control | Panel, temperature measurement, and any additional control functions. |
Compare the contents line by line
AUTOTERM offers various kits. Compare the specific package list with your drawing: What lengths are included, how many outlets are there, and are the desired marine components included? A product image is not a complete shopping list.
Example: salon and forward cabin
Write the two rooms on the list and measure each air path. Add space for a distributor and any potential silencer. Then let the installer check the dimensions and air resistance before you buy hoses. The number of outlets alone does not determine whether the heat will be distributed properly.
Include the commissioning in the quote
I would ask for startup, inspection of the installation, and a walkthrough of the operation. AUTOTERM's installation manual must be followed for the specific model, including regarding power supply, air routing, and exhaust. The heater must be able to complete its normal cool-down phase; daily shutdown must be performed using the designated control system.
A good quote shows both the parts and the work. That way, you can compare two solutions without missing necessary add-ons.
Sources and manufacturer documentation
Manufacturer documentation verified September 2026. Always follow the manual for the specific model and installation. The calculation examples are simplified examples for planning purposes.
