If you’re in the market for a new water heater, you may have come across the option of choosing a tankless water heater. These units have become increasingly popular in recent years due to their energy efficiency, compact size, and endless hot water supply. However, with so many options available, it can be overwhelming to choose the most efficient electric tankless water heater for your specific needs.
To help you make an informed decision, we’ve compiled a comprehensive guide on what to look for when selecting a tankless water heater that will provide you with the most savings on your energy bill.
What makes a tankless water heater efficient?
Before we dive into our recommendations, let’s discuss what makes a tankless water heater efficient in the first place. Traditional tank water heaters constantly heat and store water in a large tank, which can lead to a loss of heat and energy due to standby heat loss. Tankless water heaters, on the other hand, only heat water when you need it, resulting in significant energy savings.
Additionally, tankless water heaters are generally more compact and can be installed closer to the point of use, reducing the time it takes for hot water to reach your faucet or shower. This can further help you save on your water bill by minimizing the amount of water wasted while waiting for it to heat up.
Key features to look for in an efficient electric tankless water heater
When shopping for an electric tankless water heater, there are several key features to look out for to ensure that you’re getting the most efficient unit for your home. Here are some important factors to consider:
1. Energy Efficiency: Look for a tankless water heater with a high energy factor (EF) rating, which indicates how efficiently the unit uses energy to heat water. The higher the EF rating, the more energy-efficient the water heater is.
2. Flow Rate: Consider the flow rate of the tankless water heater, which indicates the amount of hot water the unit can deliver per minute. Make sure to choose a unit with a flow rate that meets your household’s hot water demands.
3. Size: Tankless water heaters come in various sizes, so be sure to choose a model that fits the space where you plan to install it. Smaller units are typically more energy-efficient, but may not provide enough hot water for larger households.
4. Temperature Control: Look for a tankless water heater with adjustable temperature settings, so you can easily customize the water temperature to your liking and avoid overheating.
5. Durability: Consider the durability and lifespan of the unit, as investing in a high-quality tankless water heater can save you money in the long run by avoiding costly repairs or replacements.
