If you’re like most people, you don’t think much about your water heater until there’s a problem. But don’t wait for your current water heater to break down—you’ll end up with whatever your plumber has on the truck—which might be all wrong for your needs. Even if you’re not ready to replace your water heater, it’s smart to know about your options—there are several types of water heaters that are economical and energy efficient.
Types of Hot Water Heaters
- Conventional storage water heaters that offer a ready reservoir (via the storage tank) of hot water.
- Demand (tankless or instantaneous) water heaters that heats water directly without the use of a storage tank.
- Heat pump water heaters that move heat from one place to another instead of generating heat directly for providing hot water.
- Solar water heaters that use the sun’s heat to provide hot water.
- Tankless coil and indirect water heaters that use a home’s space heating system to heat water.
When selecting the best type and model of water heater for your home, you also need to consider the following:
- Fuel type, availability, and cost: the fuel type or energy source you use for water heating will not only affect the water heater’s annual operation costs but also its size and energy efficiency.
- Size: to provide your household with enough hot water and to maximize efficiency, you need a properly sized water heater.
- Energy efficiency: to maximize your energy and cost savings, you want to know how energy efficient a water heater is before you purchase it.
- Operating Costs: before you purchase a water heater, it’s also a good idea to estimate its annual operating costs and compare those costs with other less or more energy-efficient models.
