When it comes to heating water in our homes, tank water heaters have been the go-to option for many years. These traditional water heaters store and heat water in a tank until it’s needed, but they can be notorious for wasting energy. However, with advancements in technology, there are now more energy efficient options available on the market.
If you’re in the market for a new water heater and want to save on your energy bills, it’s essential to invest in the most energy efficient tank water heater. This article will discuss what makes a water heater energy efficient, as well as some top options available for purchase.
Factors that Make a Water Heater Energy Efficient
Before we delve into the most energy efficient tank water heaters available, it’s important to understand what makes a water heater energy efficient in the first place. Here are some key factors to consider when looking for an energy efficient water heater:
1. Energy Factor (EF): The Energy Factor is a measure of a water heater’s overall efficiency. It takes into account the amount of hot water produced per unit of fuel consumed over a typical day. The higher the EF, the more energy efficient the water heater is.
2. Insulation: A well-insulated tank can help reduce standby heat loss, which occurs when heat escapes from the tank into the surrounding space. A water heater with adequate insulation will retain heat better and require less energy to maintain water temperature.
3. Recovery Rate: The recovery rate is the amount of time it takes for a water heater to heat a full tank of water to a desired temperature. A higher recovery rate means the water heater can quickly replenish hot water supply, reducing energy consumption.
4. Size and Capacity: Choosing a water heater that is appropriately sized for your household’s hot water needs can help avoid unnecessary energy consumption. An oversized water heater will use more energy to maintain the water temperature, while an undersized one may struggle to meet demand.
