Mabomba uingizaji hewa ni kusambazwa katika insulation kati ya mashimo na maeneo ambayo tunataka joto (ambayo inaweza kuwa, kwa mfano, ukuta wa kaskazini wa jengo – nafasi kati ya polystyrene na ukuta) chini ya ukuta katika umbali huo kufunga mashabiki wa kutolea nje miniature kilichopozwa chini kwa hewa baridi nje ya ukuta .
