"I like the heat."
Translation:J'aime la chaleur.
I thought chauffage meant "heating" -
"J'aime le chauffage" sounds quite awkward to be frank. About as off as if I washed my hands in someone's sink and said "I like the plumbing", to try to give an idea. ripcurlgirl is right about chauffage=heating (it can also be slang for heavy flirting, probably regional though)
In the situation you describe one might say "il fait bien chaud", "il fait bon ici"
