To the real estate editor:
Your Glencoe, Ill., reader who asks whether he would save money by turning down the temperature on his gas hot-water heater might like to know about the new (in the United States, but old in Europe and the Orient) tankless instant water heaters which heat only the water you use.

Fuel savings are substantial, according to literaure supplied by several manufacturers who now sell in the US.

In Massachusetts, the only instant gas water heater so far approved is the Paloma Constant-Flo. Dorothy Kano Lincoln, Mass.
