Electric Hot Water Heater Tankless Systems

As energy efficiency becomes a top priority for homeowners, electric tankless water heaters are gaining popularity for their ability to provide on-demand hot water while reducing energy consumption. Unlike traditional tank-style water heaters that continuously heat a stored amount of water, tankless systems heat water as needed. They provide significant advantages for households seeking to lower energy bills and enjoy endless hot water.

How Electric Tankless Water Heaters Work

Electric tankless water heaters function by rapidly heating water as it passes through the unit, eliminating the need for a storage tank. Cold water flows into the unit, where powerful electric heating elements instantly warm the water to the desired temperature. This system provides hot water on demand, meaning there is no waiting for a tank to refill or heat up. The key advantage here is that you’ll never run out of hot water, no matter how many showers or appliances are running—provided you have the right unit for your household needs.

Key Benefits of Electric Tankless Water Heaters

  1. Energy Efficiency: One of the standout benefits of electric tankless water heaters is their energy efficiency. Unlike tank-style heaters that constantly use energy to maintain hot water, tankless systems only activate when hot water is needed. This means your water heater consumes energy only when you turn on the tap. This results in up to 34% savings on energy bills in some households.
  2. Endless Hot Water Supply: Since the water is heated on demand, you never have to worry about running out of hot water. Whether you're running the washing machine, dishwasher, and shower simultaneously, a properly sized unit can keep up with demand.
  3. Space-Saving Design: Electric tankless units are compact and wall-mounted. It takes up much less space compared to their bulky tank counterparts. This can free up valuable room in smaller homes, apartments, or spaces where traditional tank water heaters aren’t practical.
  4. Longer Lifespan: Electric tankless water heaters have an impressive lifespan of up to 20 years or more. They outlast traditional tank heaters by almost a decade​. Their durability is a significant long-term cost benefit, as you won’t need to replace the unit as often.
  5. Reduced Carbon Footprint: These units not only help lower utility bills but also reduce greenhouse gas emissions due to their lower energy consumption. By heating water only when needed, tankless systems minimize the waste of energy that occurs with traditional heaters​.

Installation Considerations: What You Need to Know

Before switching to an electric tankless water heater, it’s important to understand the installation requirements and potential challenges. While tankless units offer many benefits, they also come with some unique installation needs.

  • Electrical Upgrades: One potential drawback is the electrical demand required to operate these units. Many homes may need to upgrade their electrical system or circuit breakers to accommodate the power requirements of a tankless water heater. This can add to the initial cost but guarantee optimal performance and safety​.
  • Professional Installation: Installing an electric tankless water heater usually requires professional assistance, especially if electrical upgrades are necessary. A certified technician will ensure that the unit is installed correctly according to local building codes.
  • Space and Placement: While these units are space-saving, they need proper ventilation and adequate space around them to function safely. Most are mounted on walls and are ideal for smaller homes or spaces with limited utility areas​.

Potential Drawbacks of Electric Tankless Water Heaters

While electric tankless water heaters are an excellent option for many households, they do have some limitations that are worth considering:

  • Limited Flow Rate: One of the most notable downsides is that tankless water heaters have a limited flow rate. While they provide an endless supply of hot water, the water flow can drop if multiple appliances or taps are drawing hot water at the same time. For larger households, you may need a higher capacity unit or multiple tankless units to meet demand during peak usage times​.
  • Upfront Cost: Electric tankless water heaters tend to be more expensive upfront than traditional tank water heaters. The initial cost is coupled with potential electrical upgrades and can make the overall investment higher. However, the energy savings over time often offset this cost​
  • Mineral Buildup: In areas with hard water, tankless water heaters can experience mineral buildup, which may reduce efficiency. Regular maintenance such as descaling, can help extend the lifespan of the unit and ensure it operates at peak performance​

Is an Electric Tankless Water Heater Right for You?

Whether or not an electric tankless water heater is right for your home depends on several factors, including your household’s hot water needs, energy efficiency goals, and budget.

  1. Household Size: If your household frequently uses hot water from multiple sources at once, consider a larger capacity unit or multiple units to avoid disruptions. For smaller households with moderate hot water needs, a single unit is often sufficient​.
  2. Energy Efficiency Goals: For homeowners looking to reduce energy consumption and lower their environmental impact, electric tankless water heaters are an excellent option. The reduction in standby heat loss alone can significantly decrease energy bills over the years​.
  3. Upfront vs. Long-Term Costs: While the initial investment in an electric tankless unit may be higher, the long-term savings in energy bills and the extended lifespan of the unit make it a cost-effective choice in the long run. Be sure to factor in installation costs and any necessary electrical upgrades when budgeting​.

Electric tankless water heaters are a modern, energy-efficient solution for today’s homeowners. They offer numerous benefits including endless hot water, energy savings, and a compact design. While the initial costs may be higher, the long-term benefits in terms of lower utility bills, reduced carbon footprint, and extended equipment lifespan make them an attractive option for many homes.
