How Do Electric Tankless Water Heaters Work?
According to A.O Smith, unlike traditional water heaters which store hot water in a tank, tankless water heaters heat water on demand as it flows through the unit, meaning there is no storage tank involved and hot water is produced only when needed. When you turn on the hot water tap, cold water passes through an electric heating element, which instantly heats the water to your desired temperature.
This means you’ll never run out of hot water, and you won’t waste energy keeping a tank of water hot all day. It’s a win-win.
Benefits of Running a Tankless Water Heater on Electricity
Electric tankless water heaters come with several advantages:
- Energy Efficiency: Since they only heat water when needed, they use less energy compared to traditional water heaters.
- Compact Design: These units are small and can be installed in tight spaces, making them ideal for apartments or homes with limited space.
- Lower Initial Cost: Electric models are generally more affordable to purchase and install than gas-powered ones.
- No Gas Line Required: If your home doesn’t have access to natural gas, an electric tankless water heater is a perfect solution.
Things to Consider Before Installing an Electric Tankless Water Heater
While electric tankless water heaters are a great option, there are a few factors to keep in mind:
- Electrical Requirements
- Electric tankless water heaters require a significant amount of power to operate. You may need to upgrade your home’s electrical system to handle the load.
- Check the unit’s specifications to ensure your home’s electrical panel can support it.
- Flow Rate
- Electric models typically have a lower flow rate compared to gas-powered ones. This means they may struggle to supply hot water to multiple fixtures simultaneously.
- If you have a large household, you might need multiple units or a higher-capacity model.
- Installation Costs
- While the unit itself is affordable, upgrading your electrical system (if needed) can add to the installation cost.
Can an Electric Tankless Water Heater Handle Your Needs?
The answer depends on your household’s hot water demand. If you live in a smaller home or apartment and don’t need to run multiple showers and appliances at the same time, an electric tankless water heater is a fantastic choice.
However, for larger households with higher water usage, you might want to consider a gas-powered model or multiple electric units to meet your needs.
