Sådan bruges størrelsesangivelsen
Dette er SejlStrøms vejledende førstevalg ved normal isolering, ikke en producentgaranti eller en beregning til helårsbrug. Arealet er det indvendige rum, der skal opvarmes. Bådlængden er kun en grov sorteringshjælp og kan ikke omregnes direkte til m². Ved frost, stort glasareal, flere kahytter eller helårsbeboelse beregner jeg behovet konkret.

Installation and choosing accessories
Bådlængde alene afgør ikke størrelsen. Følg manualen for brændstof, strøm, forbrændingsluft og gastæt udstødning til det fri.
Installation og kompatibilitet
Planlæg placering, friskluft, varmluftslanger, brændstofforsyning, strømtilslutning og udstødning som ét samlet system. Udstødningen skal være gastæt og føres sikkert ud af båden med korrekt varmeafstand til brændbart materiale.

Unsure about the size or model? I am happy to help you choose the right diesel heater for your boat or installation before you order. Compare diesel heaters
The Webasto Air Top 40 EVO boat heater 4 kW – incl. installation parts is a diesel-powered air heater for efficient heating of cabins and living spaces on board. It is an obvious choice when you want to extend the boating season and desire stable heat without being dependent on shore power.
The product can be selected by voltage so it can be adapted to the specific installation.
Guidance on size
Heated area: 11–20 m²
Boat length: 31–40 feet
This is SejlStrøm's indicative first choice for standard insulation, not a manufacturer guarantee or a calculation for year-round use. The area is the interior space that needs heating. The boat length is only a rough guide and cannot be converted directly to m². In case of frost, large glass areas, multiple cabins, or year-round living, I calculate the need specifically.

🔧 Installation and compatibility
Plan the placement, fresh air, hot air hoses, fuel supply, power connection, and exhaust as one integrated system. The exhaust must be gas-tight and safely routed out of the boat with the correct heat distance to flammable material.
📄 Manuals and documentation
💡 Tip from SejlStrøm
Calculate the heating requirement based on the boat's size and insulation, and order air hoses, nozzles, exhaust parts, and electrical connections at the same time. This ensures an installation that can be completed without missing small parts.
