Get More Miles for Your MoneyThe Sunster's ECU precisely controls injection frequency and air intake, delivering exceptional fuel efficiency of just 0.1–0.35 L/h. With the 6L built-in tank, you get approximately 17–60 hours of continuous warmth on a single fill — that's up to two nights of camping comfort from one tank. Auto Start-Stop maintains your set temperature, automatically cycling the burner to save fuel while you sleep. |

Comfort Inside, Machine OutsideThe 4-metre switch extension cable lets you mount the LCD panel indoors while the heater unit stays outside — meaning no cold drafts, no fumes inside, and precise temperature sensing from within your living space. This intelligent setup drastically reduces fuel consumption by eliminating the need to open doors for adjustments, while the heater auto-adjusts its mode based on actual indoor temperature readings. |
