Noted in “How to make your home more energy efficient — and get a tax break too,” Erica Werner, WaPo:
Radiant floor heat relies on a system of tubing underneath or incorporated into the floor of a house, which heats up when hot water is forced through it. (There are also electric and hot-air-based systems, but the water-based hydronic systems are most cost-effective and popular, according to the Energy Department.) These systems are more efficient than most baseboard or forced-air systems.
Ummmm. I live in a house built in 1938, but I don’t see any radiators. Too bad. I had the old boiler hauled out back in 2005 or somesuch. Drat.
