Factors to Consider When Choosing a Whole House Electric Tankless Water Heater
Choosing the right whole house electric tankless water heater requires careful consideration of several factors. To ensure you make the best decision, we have highlighted the critical factors to consider when purchasing an electric tankless water heater for your home.
Flow Rate and Temperature Rise
The flow rate and temperature rise are crucial factors to consider when choosing an electric tankless water heater. The flow rate is the amount of water that can pass through the unit per minute, while the temperature rise is the difference between the incoming cold water temperature and the desired output temperature. The required flow rate and temperature rise depend on the number of fixtures in your household and the climate you live in.
To determine the appropriate flow rate, calculate the total flow rate of all the fixtures in your home that may run simultaneously. Add an additional 25% to account for unexpected usage. For temperature rise, the colder the incoming water temperature, the more the unit must heat the water to achieve your desired output temperature. Consult the manufacturer's guidelines or a plumbing professional to ensure you choose the correct electric tankless water heater that meets the flow rate and temperature rise requirements of your household.
Energy Efficiency
One of the essential factors to consider when choosing an electric tankless water heater is its energy efficiency. These units only heat water when needed, which significantly reduces energy consumption and utility bills. Higher efficiency models use less energy to heat the water, which means less money spent on electrical bills and a more environmentally friendly unit. Choose a model with a high Energy Factor (EF) rating to ensure maximum energy efficiency.
Size and Installation Requirements
Electric tankless water heaters come in different sizes, and it is essential to choose a unit that is appropriately sized for your household's needs. Consider the space available for installation and whether the unit will fit within the allocated space. Additionally, ensure that the unit you choose meets the electrical requirements of your home and installation area. Consult a professional plumber or electrician to ensure proper installation, which will maximize the unit's efficiency and lifespan.
Warranty and Maintenance Needs
Another critical factor to consider when purchasing an electric tankless water heater is the warranty and maintenance needs. Look for a unit with an extended warranty period to ensure that you are protected in case of any issues with the unit. Additionally, consider the maintenance needed for your chosen unit. Electric tankless water heaters require periodic descaling and filter cleaning to maintain optimal performance. Understand the maintenance needs of the unit before purchasing to ensure you are prepared to care for it properly.
By taking these factors into account, you can choose the best whole house electric tankless water heater that provides an efficient, reliable, and cost-effective solution for hot water in your home.
