Introduction to Electric Tankless Water Heaters
What is an electric tankless water heater?
An electric tankless water heater is a device that heats water on demand, without the need for a storage tank. Unlike traditional water heaters, which keep a reservoir of hot water, best electric tankless water heater tankless models heat water directly as it flows through the unit, providing an endless supply of hot water.
How do they work?
Electric tankless water heaters use powerful electric heating elements to heat water as it passes through the unit. When a hot water tap is turned on, cold water travels through a pipe into the heater. The water is then heated by the electric elements and delivered directly to the faucet.
Benefits of electric tankless water heaters
Electric tankless water heaters offer several benefits, including energy efficiency, space-saving design, continuous hot water supply, and a longer lifespan compared to traditional tank water heaters. These units can significantly reduce energy bills and provide an eco-friendly alternative to conventional water heating methods.
Advantages of Electric Tankless Water Heaters
Energy efficiency
Electric tankless water heaters are highly energy-efficient because they only heat water when needed. This on-demand heating mechanism reduces energy waste associated with keeping a tank of water hot, leading to lower utility bills.
Continuous hot water supply
One of the biggest advantages of electric tankless water heaters is the ability to provide an uninterrupted supply of hot water. This feature is particularly beneficial for large families or households with high hot water demand.
Space-saving design
These heaters are compact and can be mounted on walls, freeing up valuable floor space. Their small size makes them ideal for homes with limited space, apartments, and even RVs.
Longer lifespan
Electric tankless water heaters generally have a longer lifespan than traditional tank heaters. With proper maintenance, they can last up to 20 years or more, providing a long-term solution for hot water needs.
How to Choose the Best Electric Tankless Water Heater
Consider your household size
The size of your household significantly impacts the type of tankless water heater you need. Larger households with higher hot water demand require units with greater flow rates to ensure a consistent supply of hot water.
Evaluate energy efficiency
Look for units with high energy efficiency ratings. Models with Energy Star certifications are often the best choices as they meet stringent energy efficiency guidelines set by the EPA.
Check the flow rate
The flow rate, measured in gallons per minute (GPM), determines how much hot water the unit can produce. Ensure the heater you choose can handle your household’s peak hot water demand.
Consider the unit’s size and design
Ensure the unit fits in the space you have available. The compact design of electric tankless water heaters makes them versatile, but it’s essential to verify dimensions before purchasing.
