Understanding Tankless Electric Water Heaters
Tankless electric water heaters, also known as demand-type heaters, provide hot water only when needed, without needing a storage tank. This direct heating mechanism eliminates standby heat losses common with traditional storage water heaters, making tankless systems more energy-efficient.
These systems typically deliver hot water at 2 to 5 gallons per minute, sufficient for most household needs. Tankless water heaters can be significantly more efficient for homes that use less than 41 gallons of hot water daily, with potential energy savings ranging from 24% to 34%.
Tankless electric water heaters heat water on demand, preventing energy waste associated with maintaining a large tank of hot water. This efficiency not only saves energy but also reduces overall utility bills. The absence of a bulky tank also means more space in your utility room, making these heaters a smart choice for modern homes.
Key Features of Tankless Electric Water Heaters
Tankless electric water heaters have several advanced features that enhance their performance and efficiency. From digital temperature control to self-modulating technology and compact designs, these features ensure you get the most out of your water heater.
Here are some key features in detail.
Digital Temperature Control
One of the standout features of tankless electric water heaters is the digital temperature control, which allows users to set precise water temperatures. This feature ensures a consistent hot water supply tailored to your specific needs. For instance, the Tempra® Plus series offers two memory presets, allowing users to switch between their preferred temperatures quickly and easily.
A digital interface makes monitoring and adjusting the water temperature simple, providing real-time data and control at your fingertips. This level of precision not only enhances comfort but also contributes to energy efficiency by avoiding water overheating.
Self-Modulating Technology
Self-modulating technology is another critical feature of tankless electric water heaters. This technology continuously monitors the incoming water temperature and flow rate, adjusting energy usage accordingly. By optimizing energy consumption based on demand, self-modulating systems ensure that you always have a consistent hot water supply without wasting energy.
This feature not only improves performance but also contributes to significant energy savings. Self-modulating technology makes tankless electric water heaters a highly efficient choice for any home by maintaining the desired water temperature with minimal energy.
Compact Design and Space Savings
Tankless electric water heaters are renowned for their compact design, which offers substantial space savings compared to traditional tank water heaters. These units require significantly less raw material for production, contributing to their smaller size and reduced environmental impact.
The compact design allows for flexible installation locations, often closer to the point of use, which enhances convenience and reduces heat loss in the pipes. Tankless electric water heaters also save several square feet of floor space, making optimizing the layout of your utility room or other installation areas easier.
Continuous Hot Water Supply
One of the most significant advantages of tankless electric water heaters is their ability to provide a continuous hot water supply. Unlike traditional heaters that rely on a storage tank, tankless systems heat water on demand, ensuring you never run out of hot water during a shower or laundry.
Households with high hot water demands can install multiple tankless units in parallel to ensure an uninterrupted supply. For instance, the Tempra 24 Plus can simultaneously serve multiple hot water demands, making it an excellent choice for larger homes.
This flexibility ensures you'll always have enough hot water to run a bath, wash dishes, or do laundry.
Energy Efficiency and Cost Savings
Tankless electric water heaters are designed to operate only when hot water is needed, significantly reducing energy consumption compared to traditional models. By heating water on demand, these systems eliminate standby energy losses associated with continuously keeping a large water tank hot. This efficiency translates into substantial cost savings on your energy bills.
For households using 41 gallons or less of hot water daily, tankless electric water heaters can consume up to 34% less energy than traditional storage tank models. Even in homes with higher hot water usage, these heaters can be up to 14% more efficient, leading to lower energy costs and reduced carbon emissions.
Choosing the Right Size for Your Home
Choosing the correctly sized tankless water heater is crucial to ensuring it efficiently meets your household’s hot water demands. Factors such as household size, peak usage times, and the number of simultaneous hot water sources play a significant role in selecting the suitable unit.
Factors to Consider
When selecting a tankless water heater, consider your household size and peak hot water usage times. Larger households typically require higher-capacity units to accommodate the simultaneous use of multiple fixtures, such as showers, dishwashers, and washing machines.
Assessing household habits and peak usage times will help you select a model that fits your needs. A sizing guide that considers these factors can help you make an informed decision, ensuring you have enough hot water when you need it most.
Sizing Guide
To determine the correct size for your tankless water heater, you’ll need to calculate the maximum flow rate required for your household. This involves considering the number of fixtures used simultaneously and their respective flow rates. Additionally, calculating the temperature rise – the difference between the desired hot and incoming water temperatures – is critical for proper sizing.
Groundwater temperature also plays a significant role in sizing. Cooler incoming water requires more energy to heat, which affects the heater's performance. Using a complete sizing guide will help you select the best model for your home, ensuring optimal performance and energy efficiency.
Installation and Maintenance
Proper installation and regular maintenance are vital to ensuring the optimal performance and longevity of your tankless electric water heater. While the installation process can be user-friendly, hiring a licensed electrician is often recommended for the best results.
Easy Installation Process
For example, the installation of Stiebel Eltron Tempra models is generally straightforward and can often be completed in under 30 minutes by a skilled DIYer or a professional. These models come with comprehensive installation manuals and supportive videos, making the process accessible for DIY enthusiasts and professionals.
Many users have reported positive installation experiences, with some managing the process with minimal issues. However, for those less confident in their DIY skills, hiring a licensed electrician ensures the installation is done correctly and safely.
Maintenance Tips
Regular maintenance is crucial for the long-term performance of your tankless electric water heater. One essential maintenance task is the periodic cleaning of the inlet water filter to prevent debris from entering the system and to maintain optimal flow performance.
Checking and replacing filters regularly can significantly prolong the lifespan of your unit. Following these maintenance tips enhances efficiency and ensures that your tankless electric water heater continues to deliver a reliable hot water supply for years to come.
