Best Electric Tankless Hot Water Heater FAQs
Is an electric tankless water heater worth it?
Yes, an electric tankless water heater is worth it. Tankless water heaters provide an endless supply of hot water, as they heat water on demand rather than storing it in a tank. This means that you won't run out of hot water, and you won't have to wait for the tank to refill and reheat. Additionally, tankless water heaters are more energy efficient than traditional tank water heaters, as they only heat water when it is needed. This can result in significant energy savings over time. Finally, tankless water heaters are more compact and take up less space than traditional tank water heaters, making them ideal for small spaces.
What is the downside of an electric tankless water heater?
The main downside of an electric tankless water heater is its high initial cost. Electric tankless water heaters are more expensive than traditional tank water heaters, and the installation costs can be even higher. Additionally, electric tankless water heaters require a larger electrical service than traditional tank water heaters, which can add to the cost of installation. Furthermore, electric tankless water heaters require a dedicated circuit, which can be expensive to install. Finally, electric tankless water heaters are not as efficient as gas tankless water heaters, so they may not be the best choice for larger households.
What is the most reliable electric hot water heater?
The most reliable electric hot water heater depends on a variety of factors, such as the size of the household, the amount of hot water needed, and the budget. Generally, tankless electric water heaters are considered to be the most reliable, as they provide an endless supply of hot water and are more energy efficient than traditional tank-style water heaters. Tankless electric water heaters are also more compact and require less maintenance than tank-style water heaters. Additionally, they are more cost-effective in the long run, as they do not require the same amount of energy to heat the water. However, tank-style water heaters are still a reliable option for households that require a large amount of hot water. Tank-style water heaters are also more affordable upfront, and they are easier to install. Ultimately, the most reliable electric hot water heater for a household depends on the individual needs and budget of the household.
What size electric tankless water heater do I need?
The size of electric tankless water heater you need depends on a few factors, such as the size of your home, the number of bathrooms, and the amount of hot water you use. Generally, a tankless water heater with a capacity of 2-5 gallons per minute (GPM) is sufficient for a small home with one or two bathrooms. For larger homes with multiple bathrooms, a tankless water heater with a capacity of 6-8 GPM is recommended. Additionally, you should consider the temperature rise you need, which is the difference between the incoming water temperature and the desired output temperature. The higher the temperature rise, the more powerful the tankless water heater needs to be. It is important to consult a professional to determine the best size tankless water heater for your home.
