In Spanish the H is silent, except with the C consonant (like in chat, champagne...).
So, Th would be pronounced like just T. For example, thermo and now culitho.

The noun "termo" in Spanish is formally recognized by the RAE to refer to a vacuum insulated food jar (such as the ones sold by Thermos®), and that is the word I was referring to, as it is the most widely identifiable use of the word "termo" in Spanish.
i.e.: "Pasame ese termo por favor?", "Se me ha quedado el termo en mi casa".
