Find the right BTU and diesel heater size (2kW, 5kW, 8kW) for your van.
2kW (6,800 BTU): Short vans, mild climates, minimal heating needs
5kW (17,000 BTU): Standard for most van builds, good down to 0°F
8kW (27,000 BTU): Extended vans, extreme cold, rapid heating
💡 Pro tip: Most van lifers choose the 5kW Chinese diesel heater. It's the right size for 90% of builds and costs $150-300.
