Also known as on-demand or instantaneous water heaters, tankless water heaters have gained popularity in recent years as an alternative to traditional tank-style heaters. If you’re contemplating the switch to a tankless water heater, it’s a good idea to consider the advantages and disadvantages of tankless water heaters.
Pros:
- First of all, they are energy efficient. Unlike traditional heaters that continuously heat and store water, tankless models only heat water as it is needed. This eliminates standby heat loss and can result in significant energy savings. According to the U.S. Department of Energy, tankless water heaters can be up to 24% to 34% more energy-efficient than conventional tank-style heaters.
- Secondly, tankless water heaters provide a continuous supply of hot water, unlike tank-style heaters that can run out of hot water if used extensively. With a tankless system, you can enjoy hot water for as long as it is needed, making it ideal for households with high hot water demands or for larger families.
- Another advantage is that tankless water heaters are compact and wall-mounted, freeing up valuable floor space that would have been occupied by a bulky tank-style heater. This makes them a great choice for smaller homes or apartments where space is limited.
- Tankless water heaters generally have a longer lifespan compared to traditional heaters. While tank-style heaters typically last around 10 to 15 years, tankless models can last up to 20 years or more with proper maintenance. This can result in long-term cost savings by avoiding the need for frequent replacements.
Cons:
- Higher Initial Cost: One drawback of tankless water heaters is their higher initial cost compared to traditional heaters. Including installation, the price can be significantly higher. However, the energy savings over time can help offset this initial investment.
- Limited Flow Rate: Although tankless water heaters provide unlimited hot water, they have a limited flow rate. This means that if multiple hot water sources are being used simultaneously, such as running a shower and dishwasher at the same time, the flow rate may decrease, leading to a drop in water pressure.
- Additional Installation Requirements: For example, you may need to upgrade your electrical system or gas line to accommodate the higher energy demands of the unit. It’s crucial to consider these factors and consult with a professional to ensure a smooth installation process.
- Maintenance: They require regular maintenance, such as descaling, to prevent mineral buildup. Neglecting maintenance can lead to decreased efficiency and potential malfunctions. Additionally, servicing a tankless unit may require specialized skills, which could result in higher maintenance costs.
While tankless water heaters offer several benefits, they also come with considerations you need to understand in order to make an informed decision.
