the lowest utility bills. The vacation/cabin setting lowers the water temperature to 50 degrees to pre­ vent freezing. If space is limited and you caimot install a larger model, some new high-quality models offer 5,500- watt (3,800 or 4,500 watts is typical) heating elements. These powerful 5,500-watt elements provide more hot water quickly. Most steel water heater tanks have a thin inner glass lining to stop corrosion. Another effective de­ sign uses a one-half-inch thick stone lining to extend the tank life. The stone also adds a little more insula­ tion value. Especially in hard water areas, select a model with larger, hand-size sediment clean-out access holes. There are also special dip tube designs that swirl lie incoming cold water to keep, sediment from buildingup. * Write for (instantly down­ load — www.dulley.com) Update Bulletin No. 568 — buyer’s guide of 12 manufacturers (55 models) of su­ per-efficient and never-leak electric water heaters listing water outputs,'EF’s, warranties, features and a savings/payback chart.

You had mentioned in a recent article that sta­ pling foil under the roof rafters would help block heat I can only find single-sided foil with a paper backing. Which way should the shiny side face? A. Stapling foil under the attic rafters will block radiant heat from a hot roof during the summer. Dur­ ing the winter, the roof does not get nearly as hot, so there is little negative effect from the foil. The shiny side should face downward toward the living area. Foil is effective, not because it reflects the heat back upward, but because the ^iny (low emissivity) surface will not readily reradiate the heatto the attic floor below.
