Buying Guide: What to Look For in a Electric Tankless Water Heaters
Understanding Electric Tankless Water Heaters
Electric tankless water heaters, often considered among the best electric tankless water heaters, provide hot water on demand, eliminating the need for a storage tank. This means you only heat water when you need it, potentially saving energy. They are compact, space-saving, and can be a great choice for smaller homes or specific applications like a bathroom sink or shower. However, they require significant electrical power, so ensuring your electrical system can handle the load is crucial before purchasing.
Key Considerations Before Buying
Before investing in one of the best electric tankless water heaters, consider your hot water needs. How many people will be using hot water simultaneously? What is the flow rate required for showers, faucets, and appliances? Next, assess your electrical capacity. Tankless heaters require high amperage circuits, and your home’s electrical panel must be able to support the load. Finally, think about the installation location. Tankless units are compact, but they still need a suitable space and proper plumbing connections.
Factors to Evaluate: Power, Flow Rate, and Efficiency
Power (measured in kW) directly impacts the water heating capacity. Higher kW models can handle more simultaneous hot water demands. Flow rate (gallons per minute, or GPM) determines how much hot water you can get at a given temperature. Choose a model that meets your household’s peak demand. Energy efficiency is another important factor. Look for models with high energy conversion rates, ideally above 95%. These best electric tankless water heaters can save you money on your electricity bill in the long run.
Installation and Maintenance
Professional installation is highly recommended for electric tankless water heaters. A qualified electrician can ensure proper wiring and circuit breaker installation, preventing electrical hazards. Plumbing connections also need to be done correctly to avoid leaks. Maintenance is relatively minimal, but periodic descaling may be necessary to remove mineral buildup, especially in areas with hard water. Refer to the manufacturer’s instructions for specific maintenance guidelines. Choosing the best electric tankless water heaters also means considering ease of maintenance.
Comparing Different Models and Brands
Research different brands and models to find the best fit for your needs and budget. Compare power ratings, flow rates, energy efficiency, and warranty terms. Read customer reviews to get insights into real-world performance and reliability. Some brands offer advanced features like digital displays, temperature control, and safety shut-off mechanisms. Consider these features when making your decision. The market for best electric tankless water heaters is competitive, so take your time and compare options.
