heizen — German conjugation
to heat
Indicative
Present (Präsens) Regular
Präsens is the default present for facts, habits, and near-future plans. German has no continuous aspect in the same way as English, so a single form often covers both “I work” and “I am working” when you add a time adverb or context.
Ich arbeite heute im Homeoffice.

Simple past (Präteritum) Regular
