Electric tankless water heaters are often hailed as the future of home heating solutions, offering an endless supply of hot water on demand. The appeal is clear, but it’s important to know that these units aren’t without their quirks. After working with various clients and hearing their stories, we’ve learned that a few common issues tend to arise with these systems. If you’re thinking of switching to tankless or already have one, this guide will give you insight into the problems you might encounter.
In this blog, we’ll share the typical issues, how to address them, and when it is time to call for water heater repair minneapolis. Let’s begin!
What Is an Electric Tankless Water Heater?
An electric tankless water heater is a type of heating system that provides hot water as needed without storing it in a tank. Unlike other water heaters that heat and store a massive volume of water constantly, these systems only heat water when it’s needed. As water flows through the unit, heating elements quickly warm it, delivering a continuous supply of hot water. This type of water heater is more energy-efficient because it eliminates standby heat loss, making it a popular choice for homeowners looking to save on their energy bills and reduce their environmental footprint.
Different Types of Electric Tankless Water Heaters
- Whole-House Electric Tankless Heaters
These systems provide hot water for the entire home, including showers, sinks, and appliances. They are strong enough to handle multiple uses at once, which makes them great for larger households. However, they need more power to work because they heat a lot of water quickly.
- Point-of-Use Electric Tankless Heaters
These are smaller units that deliver hot water to one specific spot, like a sink or shower. They’re perfect for small areas where you only need hot water in one place. Point-of-use heaters save energy and reduce waiting time for hot water.
- Hybrid Electric Tankless Heaters
These combine a small storage tank with a tankless system. The small tank gives you quick hot water, while the tankless part heats more water as you need it. This option is good for homes with medium hot water needs because it reduces waiting time while still being energy efficient.
Common Issues with Electric Tankless Water Heaters
This type of heater is becoming a popular choice for homeowners who want energy efficiency and an endless supply of hot water. However, like any modern appliance, they come with their own set of challenges. Many users have shared their experiences with these systems, and a few common issues tend to arise.
While these problems are usually manageable, being aware of them can help you maintain your water heater and ensure it functions properly. Below, we’ll explore some of the most frequent concerns that come up with electric tankless water heaters and what you can do about them.
1. Inconsistent Water Temperature
Many homeowners report inconsistent water temperature as a common issue with this type of heater. This usually happens when multiple fixtures, like showers or appliances, are in use at the same time. The unit can struggle to heat enough water for everyone, causing the temperature to fluctuate. While it’s designed to provide endless hot water, the system can be stretched too thin, especially in larger households. This issue can often be solved by managing water usage or upgrading to a unit with a higher flow rate.
2. Flow Rate Limitations
An electric tankless water heater can only heat a certain amount of water at once, meaning they have a limited flow rate. If you use more water than the system can handle, the temperature may drop, and you won’t get the hot water you expect. This is a common problem in larger homes where multiple showers or appliances run at the same time. The solution might be installing more than one unit or choosing a more powerful model that can meet your household’s hot water needs.
3. Power Supply Requirements
These systems require a significant amount of electrical power to function. If your home’s electrical system isn’t set up to handle that load, you might run into issues like tripped circuit breakers or the water heater not working properly. In many cases, upgrading your electrical panel or wiring is necessary to accommodate the unit. This can be a costly and time-consuming process but is essential for ensuring the unit operates correctly without any interruptions.
4. Mineral Buildup
Hard water can be a real problem for an electric tankless water heater because it leads to mineral buildup inside the unit. Over time, this buildup reduces the efficiency of the heating elements, meaning the water might not heat as quickly or to the desired temperature. If left untreated, mineral deposits can also restrict water flow. Regular maintenance, such as flushing the system, can help prevent these issues and keep your heater running smoothly.
5. Initial Installation Costs
While this water heater is known for saving energy and reducing costs in the long run, the initial installation can be expensive. Many homeowners are surprised by the cost of upgrading electrical systems, plumbing, or other necessary components to support the unit. These upfront costs can add up quickly, making it important to budget for installation when considering this type of water heater.
6. Delayed Hot Water Delivery
Despite being designed to provide instant hot water, electric tankless water heaters sometimes have a slight delay before the hot water reaches your tap. This is especially true if the heater is located far from the point of use, like a distant bathroom or kitchen. The water has to travel through the pipes first, which can take a little time. Although this delay is usually minimal, it can be frustrating for users expecting immediate hot water.
Frequently Asked Questions
Are electric tankless water heaters more energy-efficient than traditional water heaters?
Yes, they are generally more energy-efficient because they only heat water as needed, rather than maintaining a tank of hot water at all times. This reduces standby energy loss and can lead to lower energy bills over time.
How long do tankless electric water heaters typically last?
On average, they last around 15 to 20 years, which is longer than most traditional tank-style water heaters. With regular maintenance, they can last even longer.
Do electric tankless water heaters require a lot of maintenance?
While they are relatively low-maintenance, they do require some upkeep, such as descaling, to prevent mineral buildup in hard water areas. It’s also a good idea to have a professional check the unit annually to ensure it’s running efficiently.
Can an electric tankless water heater be installed in any home?
Yes, they can be installed in most homes, but it’s important to ensure that your home’s electrical system can support the unit. Some homes may need upgrades to the electrical panel or wiring before installation.
