Electric Tankless Water Heaters Myths

In recent years, electric tankless water heaters have become very popular for their energy efficiency and compact design. However, there are several myths surrounding these innovative devices that might make homeowners hesitant to make the switch. At Rooter Hero Plumbing & Air, we offer dependable plumbing service for local clients, and we want to clear up any confusion and provide you with accurate information. Here are four common myths about electric tankless water heaters.

Tankless Water Heaters Will Provide Hot Water Instantly

One misconception about tankless water heaters is that they can provide instant hot water the moment you turn on the tap. While these heaters do heat water on demand, there is still a brief delay as the water travels from the heater to your faucet. Traditional tank water heaters hold a reservoir of pre-heated water, which can give the impression of quicker delivery, especially if the tank is located close to the point of use. Electric tankless water heaters begin heating water the moment you turn on the hot water tap, which means you may experience a slight lag, particularly if the unit is situated far from the faucet. The delay is often just a few seconds, but it's not the instant hot water some people expect. It's important to position your tankless water heater strategically within your home to minimize this delay.

Tankless Water Heaters Are Simple to Install

Another myth is that electric tankless water heaters are very easy to install and can be a DIY project. In reality, while they are generally easier to install than gas tankless heaters due to the absence of venting requirements, there are still complexities involved. Electric tankless water heaters require a substantial electrical supply, and in many cases, your home’s electrical system may need upgrading to accommodate the additional load. A proper water heater installation involves not only ensuring sufficient electrical capacity but also setting up the appropriate wiring and breakers. Incorrect installation can lead to performance issues, void warranties, or even pose safety risks. Therefore, it's strongly recommended to have a professional plumber handle the installation to ensure everything is done correctly and safely.

On-Demand Water Heaters Don’t Need Maintenance

A common belief is that electric tankless water heaters are maintenance-free. While these units do require less upkeep than traditional tank heaters, they still need a regular maintenance plumbing service to operate efficiently and extend their lifespan. Over time, mineral deposits may also build up inside the heater, especially in regions with hard water. This can reduce efficiency and lead to potential damage. To keep your electric tankless water heater in top condition, it’s important to perform periodic descaling and flushing. This process removes mineral buildup and ensures the heating elements remain efficient. Regular checks of the system’s filters and components can also help prevent minor issues from getting worse.

Tankless Units Will Reduce Hot Water Flow

Some homeowners worry that electric tankless water heaters will reduce the flow of hot water, leading to a weak stream that’s insufficient for their needs. This myth arises from instances where the heater is improperly sized for the household's hot water demand. Tankless water heaters need to be appropriately matched to the household’s usage to ensure they can supply sufficient hot water during peak times. An electric tankless water heater that is too small for your needs might struggle to deliver hot water for multiple uses simultaneously, such as showering and running the dishwasher. However, a properly sized unit will provide a consistent flow of hot water. It’s important to work with a plumber to determine the right size and model for your home.

Do You Need a Water Heater Installation or Plumbing Repair Service
