The Ultimate Buying Guide: Your Guide to Tankless Electric Water Heaters
Tankless electric water heaters are a smart choice for many homes. They heat water only when you need it. This saves energy and space. Let’s dive into what makes a good tankless electric water heater.
Key Features to Look For
When choosing a tankless electric water heater, several features are important.
1. Flow Rate (GPM)
This tells you how much hot water the heater can provide at once. Look at gallons per minute (GPM). A higher GPM means more hot water is available. For a small apartment, 1-2 GPM might be enough. For a family home with multiple showers, you’ll need 3-5 GPM or more.
2. Temperature Rise
This is how much the heater can raise the water temperature. If your cold water is very cold, you need a higher temperature rise. For example, if your cold water is 50°F and you want 100°F water, you need a 50°F rise.
3. Energy Efficiency (EF)
This rating shows how well the heater converts electricity into hot water. Higher numbers mean more savings on your energy bill. Look for models with a high Energy Factor.
4. Size and Compactness
Tankless heaters are small. They are great for saving space. Check the dimensions to make sure it fits where you plan to put it.
5. Digital Controls and Smart Features
Some models have digital displays. You can set the exact water temperature. Smart features let you control the heater with your phone. This makes it easy to adjust settings.
Important Materials
The materials used in a tankless electric water heater affect its durability and performance.
- Heating Elements: These are usually made of stainless steel or copper. Copper heats water faster and is more efficient. Stainless steel is very durable.
- Outer Casing: The outside is often made of durable plastic or metal. This protects the inner workings.
Factors That Improve or Reduce Quality
Several things make a tankless electric water heater work better or worse.
- Brand Reputation: Well-known brands often make higher-quality products. They also offer better warranties and customer service.
- Warranty: A good warranty shows the manufacturer’s confidence in their product. Look for at least a 5-year warranty on parts and 10 years on the tank.
- Installation: Proper installation is key. If it’s not installed correctly, it might not work well or could even be a safety hazard. It’s best to hire a professional.
- Maintenance: Regular cleaning can help your heater last longer. Mineral buildup can reduce efficiency.
User Experience and Use Cases
Tankless electric water heaters offer a great user experience.
- Endless Hot Water: Unlike tank heaters, they don’t run out of hot water. You can shower, do laundry, and run the dishwasher all at once without interruption.
- Energy Savings: Because they only heat water when needed, they use less energy. This means lower electricity bills.
- Space Saving: Their small size is a big advantage. They can be mounted on a wall, freeing up floor space.
- Ideal for:
- Small homes and apartments where space is limited.
