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.

What is included

  • Diesel luftvarmer enhed
  • Brændstofpumpe
  • Udstødningsrør
  • Luftslanger og fittings
  • Monteringsdele
  • Betjeningspanel

Installation and choosing accessories

Bådlængde alene afgør ikke størrelsen. Følg manualen for brændstof, strøm, forbrændingsluft og gastæt udstødning til det fri.

Installation

Installationen er forholdsvis enkel og kan klares af de fleste med lidt teknisk forståelse. Varmeren monteres typisk i et opbevaringsrum, under en bænk eller i motorrum med korrekt ventilation.

Det er vigtigt at:

  • føre udstødning sikkert ud af båden/køretøjet
  • sikre korrekt brændstoftilførsel
  • bruge passende kabeldimensioner

Full product description

JP Heater 4 kW diesel air heater is an efficient and reliable solution for heating your boat, motorhome, van, or workshop. It is designed to deliver rapid heat—even in cold and damp environments—and ensures a comfortable temperature with low power and fuel consumption.

It is an obvious solution for those who want a stable heat source without being dependent on shore power.


Guideline sizing

Heated area: 11–20 m²
Boat length: 31–40 feet

This is SejlStrøm’s suggested first choice for normal insulation, not a manufacturer guarantee or a calculation for year-round use. The area refers to the interior space to be heated. The boat length is only a rough guide and cannot be converted directly to m². In the case of frost, large glass areas, multiple cabins, or year-round living, I will calculate the specific requirements.

⚡ Benefits

  • Powerful 4 kW heating output – rapid heating
  • 12V operation – perfect for boats and off-grid setups
  • Low diesel and power consumption
  • Stable operation in cold temperatures
  • Compact design – easy to install
  • Suitable for both recreational and professional use
  • Good solution for boats, vans, camping, and small rooms

⛵ Suitable for

  • Sailboats and motorboats
  • Motorhomes and vans
  • Summer houses without fixed electricity
  • Workshops and garages
  • Hunting cabins and off-grid solutions

It is important to:

  • safely route the exhaust out of the boat/vehicle
  • ensure correct fuel supply
  • use appropriate cable dimensions

💡 Tip from SejlStrøm

If you are using the heater in a boat, I recommend combining it with a lithium battery and possibly solar panels. This provides a solution where you can stay warm for longer periods without starting the engine.
