To make sure you're not testing too early, assume the sperm had very long lives (5 days is considered a very long sperm life) and that conception occurred then.

A gas water heater will recover in half the time of an electric unit. A 40-gallon gas water heater can recover in about an hour. Recovery for a 40-gallon electric water heater takes about two hours.

Water heaters tend to last seven to 15 years.ost residential water heaters cost $150 to $400 for either gas or electric, plus $200 to $450 if you have a plumber install it.
