hot water boiler efficiency

Are Propane Water Heaters Efficient? (with pictures)

Often, efficiency is based not so much on the heater itself, but on how a homeowner cares for and uses it. Heating the water for a 20-minute shower requires less power than heating water for a 30-minute shower. Also, insulation of both the water heater itself, and hot water pipes, will do much do reduce stand-by heat loss.
