When selecting a new water heater for your home, choose a water heating system that will not only provide enough hot water but also that will do so energy efficiently, saving you money. This includes considering the different types of water heaters available and determining the right size and fuel source for your home.
TYPES OF WATER HEATERS
It's a good idea to know the different types of water heaters available before you purchase one:
When selecting the best type and model of water heater for your home, consider the following:

FUEL TYPES, AVAILABILITY AND COSTS FOR WATER HEATING
When selecting a new water heater, it's important to consider what fuel type or energy source you will use, including its availability and cost. The fuel used by a water heating system will not only affect annual operation costs but also the water heater's size and energy efficiency.
EXPLORING WATER HEATER OPTIONS BY Fuel type and its availability in your area may narrow your water heater choices. The following is a list of water heater options by fuel or energy source:
COMPARING FUEL COSTS AND WATER HEATER TYPES
If you have more than one fuel type available in your area, it's a good idea to compare fuel costs, especially if you're building a new home. Even if you're replacing a water heater, you may find that you'll save more money in the long run if you use a different fuel or energy source. Contact your utility for current fuel costs or rates.
The type of water heater you choose will also affect your water heating costs. One type of water heater may use a fuel type more efficiently than another type of water heater. For example, an electric heat pump water heater typically is more energy efficient than an electric conventional storage water heater. Also, an electric heat pump water heater might have lower energy costs because of its higher efficiency than a gas-fired conventional storage water heater, even though local natural gas costs might be lower than the electricity rates.
