Facts About Water Heaters

    
A critical household appliance is your water heater. Powered by electricity, the water heater warms cold water and prepares it for use in your showers, baths, washing machines and dishwashers. If you own a house, chances are you take your water heater for granted. They sit quietly in your basement and go about their business of heating water without a lot of fuss.

HOW DO WATER HEATER WORKS?

Whenever you turn on a water faucet or have a hot shower, heated waters drawn from the top of the tank and is replaced by cold water that is carried to the bottom through the dip tube. When the water temperature drops, a thermostat activates the heating elements in an electric model. An electric water heater needs no venting. In both, an anti-corrosion anode attracts that would otherwise attack the tank's walls.
 


SELECTING A WATER HEATER

​Most of us don't bother shopping for a new water heater unit until it's too late. Whether you're replacing an old water heater or installing one in a new house, it's important to look at some of the options available.

TYPE - there are two main types of water heaters: Instant electric water heaters & Storage type electric water heaters. Choosing them depends on how much hot water you want to use, how much electricity costs and where you live.
CAPACITY - decide what size or capacity of water heater you'll need, choose the capacity based on: the number of users, the number of showers and bathtubs, and whether or not you have a dishwasher. We have stock models ranging from 4 to 132 gallons. - try to choose a water heater made with stainless steel to eliminate corrosion at tank openings.
SELF-CLEANING - reduces lime sediments build-up.
RECOVERY SPEED - the faster a water heater can replace hot water, the more energy it will use. If you are a constantly in need of a larger supply of hot water, the better recovery speed should be.
FIRST-HOUR RATING - find out what the first hour rating (FHR) is to get an idea of how much hot water will be available during consistent use.
ENERGY EFFICIENCY - this is indicated by its Energy Factor (EF). This is based on how much heat is transferred to the water, standby heat loss in an hour.
TOTAL COST - Try to estimate how much a heater will cost over its lifetime. For instance, what is initial investment cost, running or operation costs and maintenance costs if there are any.

SIZING A WATER HEATER

To determine how big a storage water heater you need: Estimate what time of the day (morning or evening) your family is likely require the greatest amount of hot water. Calculate the maximum expected hot water demand for the peak hour. Select a water heater with a "first-hour rating" (FHR) that is nearly equal to your estimated peak-hour usage. Since the first-hour rating includes the recovery rate, a smaller unit with a good recovery rate outperform a larger unit with a lower recovery unit.

HOT BATH, GOOD FOR THE HEART

In addition to making you feel clean and refreshed, a steamy hot bath may be good for the heart, according to a new study from Japan. Researchers found that warmth baths improved exercise endurance in the elderly, regardless of their heart condition.

They studied 16 elderly Japanese men and women and found out that just ten minutes of soaking in a hot bath (41-degrees Farenheit) boosted performance on a treadmill and reduced fatigue and leg pain.

In fact, according to Dr. Tanaka, warm baths seem not only safe for the heart, but they also appear to dilate blood vessels and thus allow more blood (and oxygen) to get the heart muscle.
