6 Reasons to Install Electric Tankless Water Heaters

An electric tankless water heater is an excellent choice for saving energy and space.

Here are our top six reasons why you should consider an electric tankless system for your next water heater installation:

#1. Endless Hot Water Supply

Many of us live with someone who takes their time in the shower. However, with an electric tankless water heater, you no longer have to worry about that person using every drop of hot water. This is because tankless systems can generate an endless supply of it.

Instead of storing water inside of a tank, electric tankless water heaters operate by drawing cold water directly through the pipes. The water then passes through the heat exchanger, where an electric element heats it in an instant. Every time you turn on the tap, the water is already flowing hot and will stay hot until you turn it off.

Please note that some tankless systems have temperature stability while others do not. Whole house units, such as the Bosch Tronic 6100 C, usually have a thermostatic control since they are designed to supply all the hot water needs for the home. However, point-of-use systems like the Bosch Tronic 4000 C do not and should therefore, only be used for one sink.

#2. Energy Efficient

Tankless water heaters conserve energy by avoiding heat loss. In storage water heaters, the water sitting in the tank loses some of its heat over time, even when the water heater is not in use. Since there is no stand-by heat loss with tankless systems, no energy is wasted.

The energy efficiency gains from this are significant. According to the U.S. Department of Energy, tankless water heaters are 24–34% more energy efficient than storage water heaters in households that use fewer than 41 gallons of hot water per day. For context, 41 gallons is around the equivalent of two showers a day plus a dishwasher and bathroom for a two-person household.

The median home in the United States averages 56 gallons daily. However, even in homes that use a lot of hot water, say 86 gallons per day, the agency still reports an increase in efficiency by 8–14%.

#3. Great for Seasonal Usage

Not every building is used year-round. Vacation homes, stadiums, schools, and in-law apartments are all examples of places where you would not necessarily need (or want to pay for) hot water all year. By installing tankless systems in these buildings, you can save a lot of energy, since tankless units only heat up water when you need it. This can help you save money on your water bills as well.

#4. Easy to Install and Maintain

Tankless water heaters are by far the smallest systems on the market. Think 25 pounds for an average tankless unit versus over 100 pounds for a storage water heater. The Bosch Tronic systems are even lighter than average, weighing in at only 17 pounds. Installing a tankless unit is only a one-person job!

Tankless systems can be easily mounted to the wall near an electrical source. Point-of-use units can be installed right underneath the sink. No venting is required.

Maintenance is very straightforward as well. The most important thing is to prevent mineral deposits from building, as they can cause damage to the unit if left untreated. If you are a homeowner, we recommend having a professional plumber come out once a year to flush the water heater and ensure everything is working as it should.

#5. A Perfect Fit for Many Applications

Because tankless water heaters are so compact, they are versatile and can accommodate the hot water needs of many types of buildings.

For use inside the home, you could consider installing a whole house system, such as the Bosch Tronic 6100 C, which boasts 95% efficiency and is designed to be powerful enough to provide hot water for the entire household.

However, sometimes you only need hot water in a smaller area, such as underneath a sink in the garage or in the bathroom of an office building. In this case, a point-of-use water heater like the Bosch Tronic 4000 C is the way to go. Point-of-use electric tankless water heaters are perfect for any single application with small load requirements, including:

  • Kitchens & Bathrooms
  • RVs
  • Mobile Homes & Boats
  • Apartments & Garages
  • Warehouses & Factories
  • Stores & Offices
  • Restaurants & Hotels

#6. Tankless Systems Are Electrifying the Market
