Your home hot water tank will be powered by either gas, electricity or propane.
Commercial water tank sizes can vary greatly from 40 to over 80 US gallons.
Common residential water heater sizes are:
» 40 US gallons
» 50 US gallons
» 60 US gallons
» 75-80 US gallons
Larger tanks emit more carbon monxide and require a larger vent to emit this harmful gas away from your home, so upgrading your water heater size may require a venting upgrade
Small hot water tanks can be installed to supplement your regular system or to use for specific purposes, such as providing hot water to a single sink or small commerical washroom. These small water tanks are generally only available in electric power.
Compare these features when choosing a water heater:
|Comparison||Definition||In Electric Powered Tanks…||In Gas Powered Tanks…||Recommendation|
|Efficiency Rating||Percentage of heat transfer from the energy source to your water||88-95% (water is heated through heating elements placed inside the tank).||55-65% (water is heated below the tank through a gas burner).||Choose a higher efficiency product|
|Recovery Rate||Amount of hot water the tank can produce in 1 hour (with 90ºF increase in water temperature)||20-22 gallons/hr||30-40 gallons/hr||Gas tanks produce more hot water in less time|
|First Hour Rating||Amount of hot water the tank can produce in 1 hour of continuous usage||50 gallon tank ranges 70-80 gallons||50 gallon tank around 60 gallons||Depends on your needs|
|Estimated Operating Costs||Cost to run the water heater per year||(@ $0.086 kilowatt/hr) About $400/yr||(@ 0.50/therm) About $120-130 per year||Depends on your budget|
