1) Heat traps added to water heater

Make your own heat traps to stop upward heat loss

2) Bond pipes together to prevent corrosion of tank

Add copper wire between hot and cold pipes/ prevent stray current corrosion
Heat trap nipples
Hot side and cold side heat trap nipples

Factory-installed heat trap nipples/ heat trap inserts/ 

Save $2 per year energy cost
Manufacturers add heat traps so they can claim greater efficiency
However these heat traps can clog, especially after pipe repairs upline from water heater
Water heater can make noise and whistling sounds.
Recommend removing heat traps, and installing pex-lined nipple
Low hot water pressure
Noisy water heater

Pex-lined nipples

Less corrosion
Prevent electrolitic deterioration when connecting copper and galvanized

All Costs are energyso total energy-cost equals cost of water heater, plus installation, plus expected repairs-and-parts, plus water softener-and-filter, plus disposal-recycling cost, divided by years of tank life. These numbers are added to monthy energy cost to measure true energy cost & efficiency of a water heater.
Government/industry efficiency numbers consider only energy cost per gallon of heated water.
