family. The Air 4D has twice the maximum heat output, nearly twice the maximum airflow, a larger heater body and higher maximum fuel and electrical consumption.\u003c\/p\u003e\n\u003ch3\u003eShould I automatically choose the 4 kW model?\u003c\/h3\u003e\n\u003cp\u003eNot necessarily. Correct sizing depends on the heated volume, insulation, expected outside temperature and duct design. An oversized heater may spend more time operating at low output, while an undersized heater may struggle in colder conditions.\u003c\/p\u003e\n\u003ch3\u003eCan these kits be used for marine installations?\u003c\/h3\u003e\n\u003cp\u003eThese variants are configured as RV kits.
