Confusing syntax in the answer.

Player #120374466, Did you completely ignore the word "traditionally" in the question. I am pretty sure an electrical system was not invented at that time.

I totally skipped over the unknown word and chose Radiator. Partial credit for thinking of radiant floor heating.
