"The plumber that came to replace it described it like this. A water heater is like a thermos bottle, it's a glass vessel thats insulated in a thin steal container. "
"A standard gas storage water heater is like a water tank sitting atop of a gas fireplace with the chimney running straight up through the middle, exiting at the top. "
"Your water heater is like a big pressure cooker. Water is heated in a steel tank. Steam is produced which increases the pressure in the tank. On the top of your water heater is a pressure release valve. Should your water heater thermostat malfunction and the temperature build up to a dangerous level, this valve will open and let the pressure escape."
"God's grace is the hand which adjusts the switch. It is up to you whether you cooperate and allow the switch to be turned to "max heat". The water heater is like the Holy Spirit, firing us up with the love of God. If we don't cooperate with grace and allow our switches to be moved accordingly, we won't become fired up! If we close ourselves off to God and His love, we will simply be cold water on a winter morning. No one really likes cold showers in the winter! "
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
