Residential Storage water heater

Also referred to as tank-type or tank style units. Residential
water heating units range in size from 2 1/2 gallon to 120 gallons.
Most common are electric and gas ( natural and lp).


Gas water heaters

Gas units are popular among larger families because of their quick
recovery. Operating cost of a gas unit depends on the area you live
in and time of year.
Liquid propane ( lp ) can range from $.80 a gallon during the summer
months and upward $4.00 a gallon in winter months. Natural gas
prices are generally stable.

Gas units have generally become more complicated and less reliable
over the last several years.
With the event of digital gas valves, inaccessible fresh air vents
mounted in the bottom of the unit, hard to find unusual parts,
homeowners find themselves paying for high price service calls
for what was once a simple do-it-yourself repair.

If you are shopping for a new gas unit, keep it simple if you expect
to do future repairs yourself. Look for a heater with the old tried
and true manual gas valve. Fresh air vents should be on the side
of heater where the filters are easily accessible.

The thermocouple should have standard right hand threads that
have been used for the last 70 or so years. Left hand thread
thermocouples are hard to find and cost much more than the
standard thermocouple.

Electric Water Heaters

Improvement to electric units have been great for consumers. Low watt density elements create less sediment and last much longer than standard high watt density elements. Less sediment means longer tank life. Two anode rods instead of one also increases the life expectancy of the tank.
