Customer Questions & Answers
-
Question:
What are the main benefits of the EcoSmart ECOS 12 tankless electric water heater?
Answer: The EcoSmart ECOS 12 offers endless hot water, space-saving design, and energy efficiency. Unlike traditional water heaters, it heats water on demand, ensuring you never run out of hot water, which is particularly useful during peak usage times. Its compact size makes it suitable for smaller spaces or homes with limited installation options. Families can benefit from this feature, as multiple hot water taps can be used simultaneously without any drop in temperature. -
Question:
How does the EcoSmart ECOS 12 save energy compared to traditional water heaters?
Answer: This unit operates on an on-demand heating system, which only heats water as it flows through the unit, minimizing energy loss associated with keeping a reservoir of hot water. This results in lower energy bills compared to conventional tank-style water heaters. For homeowners, this means savings can be observed over time, especially in homes where hot water usage is high but not continuous throughout the day. -
Question:
Can the EcoSmart ECOS 12 handle multiple hot water demands at once?
Answer: Yes, the EcoSmart ECOS 12 can provide up to 2.9 gallons per minute (GPM) at a consistent temperature depending on your inlet water temperature. This allows for simultaneous use of fixtures such as showers, sinks, and even appliances, making it ideal for families or homes with multiple bathrooms. For instance, you can enjoy a hot shower while washing dishes in the kitchen without any concerns about running out of hot water. -
Question:
What are the installation requirements for the EcoSmart ECOS 12?
Answer: The EcoSmart ECOS 12 requires a standard 240-volt electrical connection and a dedicated 50-amp circuit for optimal performance. Since this is a tankless system, installation can be done indoors or outdoors as long as it’s protected from freezing temperatures. Homeowners should consult with a licensed electrician to ensure proper installation to maintain efficiency and safety over the unit's lifespan. -
Question:
What temperature range can I set the EcoSmart ECOS 12 to?
Answer: The EcoSmart ECOS 12 allows you to adjust the water temperature between 80°F and 140°F. This flexibility helps in catering to different family needs, from comfortable shower temperatures to higher demands for cleaning and sanitization. The digital display makes temperature adjustments straightforward, ensuring that you get the right level of comfort with each use. -
Question:
Is the EcoSmart ECOS 12 suitable for larger homes or properties?
Answer: While the EcoSmart ECOS 12 is excellent for small to medium-sized homes, its performance might be limited in larger residences with high simultaneous demand. For homes with multiple kitchens and bathrooms, it may be necessary to install more than one unit to meet the hot water needs effectively. Identifying peak usage times can help determine if this unit fits your family's requirements. -
Question:
How does the EcoSmart ECOS 12 impact space utilization in my home?
Answer: With its compact and wall-mounted design, the EcoSmart ECOS 12 takes up significantly less space compared to traditional water heaters. This is especially advantageous for apartments or homes with limited utility space. You can turn a tight laundry area or closet into a more functional space, leaving room for additional storage or appliances, while still providing an efficient hot water solution. -
Question:
What maintenance does the EcoSmart ECOS 12 require?
Answer: The EcoSmart ECOS 12 requires minimal maintenance, primarily involving routine descaling and cleaning of the heating elements to allow the heater to operate at peak efficiency. Depending on water quality, descaling can be performed annually or bi-annually to prevent mineral buildup. Keeping up with maintenance will help prolong the lifespan of the unit and maintain a consistent hot water supply for daily use. -
Question:
What features make the EcoSmart ECOS 12 user-friendly?
Answer: The EcoSmart ECOS 12 features a digital display that provides clear information on the set temperature and system status. This user-friendly interface makes it easy to adjust settings to meet your preferences. Additionally, the compact design and wall-mountable feature simplify the installation process, allowing homeowners to reference controls easily for convenience. -
