When you need a new water heater for your home, you have many different options and features to consider. Your plumbing contractor can help you choose and install a water heater that’s right for your home, but before you start shopping you should understand the difference between types of water heaters and how to choose one that will efficiently provide sufficient hot water for you and your family.
There are many different types of water heaters available. The most common type is a conventional storage type water heater that heats a tank of water and keeps it hot for use when needed. Demand water heaters (also called tankless water heaters) are more efficient than storage type water heaters and take up less space. They only heat water as it is needed.
Heat pump water heaters are even more efficient because they use electricity to move heat rather than to create heat. They are often combined with a heat pump heating and cooling system. Solar water heaters use sunshine to heat water for your home.
The operating cost of the water heater is often more important than the initial cost of the appliance. In addition to the cost of the water heater, you should factor in the cost of maintenance and the cost of the fuel to operate the water heater.
You may live in an area where several types of fuel are available. Electricity, natural gas, propane, and fuel oil are common fuels for water heaters. Fuel costs vary throughout the country and you should compare the fuel costs for fuels available in your area to determine what type of water heater is the most cost effective.
