How to say "warmth" in Japanese

• ぬくもりCommon
  nounCovers gentle, comforting warmth, physical or emotional — the warmth of sunlight, of a body, or of human kindness. Usually written in kana alone, it is a common word for warmth you can feel.
• 温熱おんねつCommon
  no-adjectiveWarmth here means physical heat rather than a feeling; the word also covers heat itself. It turns up mainly in scientific and medical writing, so it is seldom the word for a warm feeling.
• 潤いうるおいCommon
  nounHere 'warmth' is only one sense among several: the figurative warmth of richness and pleasant fullness that makes life or something else more appealing. It is not the word for physical warmth.
  犬いぬは確たしかに家庭かていに何なんか潤うるおいを与あたえているね。↗

  Man's best friend certainly makes a good addition to a household.

Choose 「ぬくもり」 for gentle felt warmth, physical or emotional; 温熱 for warmth as physical heat in scientific or medical contexts; and 「潤い」 only for figurative warmth — the richness that makes life feel fuller and more pleasant.
