When you're choosing a water heater, don't be tempted to simply buy the lowest-cost model available. Water heating uses too much energy to make the decision lightly. The unit's initial cost is a small fraction of the money that will be spent operating it over its lifetime.

Homeowners' insurance policies typically insure the contents of the home for a percentage of the structure's replacement cost. But chances are your furnishings and other "stuff" haven't increased in value as rapidly as your home has appreciated over the past three or four years. As a result, you may be able to shave something off your escalating insurance premium by reviewing the inside coverage amount.
An easy way to estimate how much a stack of plywood will weigh is to figure about 25 lbs. per 1/4 in. of thickness. For example, one 4x8-ft. sheet of 1/4-in. plywood will weigh about 25 lbs., 1/2-in. about 50 lbs., and 3/4-in. about 75 lbs. This can help you decide how many trips you need to make to get a stack home, or whether you should have it delivered.
