Usage tips
Separable verb
'Anheizen' (to fire up / fuel / spur on) is a separable verb made up of 'an' and 'heizen' (to heat). In a main clause, the prefix appears at the end of the sentence; in a subordinate clause, the verb remains together. With the infinitive preceded by 'zu', 'zu' comes between the prefix and the verb.
EXAMPLE
Sie heizt den Kamin jeden Morgen an.
She lights the fire in the fireplace every morning.
Er friert, weil niemand den Ofen anheizt.
He is cold because nobody fires up the stove.
Wir versuchen, den Grill schnell anzuheizen.
We are trying to fire up the grill quickly.
Typical collocations
In the meaning related to heat, 'anheizen' (to fire up) is often used with 'Feuer' (fire), 'Ofen' (stove), 'Kamin' (fireplace), or 'Grill' (grill) as the object.
EXAMPLE

Abstract objects
With a figurative development, abstract terms such as 'Streit' (argument), 'Debatte' (debate), 'Konflikt' (conflict), or 'Stimmung' (mood) often appear as the object. 'Anheizen' (to fuel) then describes making this development more intense or tense.
