These types of water heaters are easy to install and maintain and can provide an endless supply of hot water. But before you buy one, there are a few things you should know about these units so that you can decide if it’s the right choice for your RV.
110-Volt Tankless Water Heater for RV: Advantages and Disadvantages
We will explore the advantages and disadvantages of using a 110-volt tankless water heater for your RV, helping you make an informed decision.
Advantages of a 110-Volt Tankless Water Heater for RV:
- Compact Size: One of the significant advantages of a 110-volt tankless water heater is its compact size. These units are designed to fit in small spaces, making them ideal for RVs where space is limited. Their compact nature allows for easier installation and frees up valuable storage space in your RV.
- Energy Efficiency: 110-volt tankless water heaters are known for their energy efficiency. Unlike traditional water heaters with storage tanks that continuously heat and reheat water, tankless heaters only heat water when needed. This on-demand heating reduces energy consumption, resulting in lower utility bills and reduced environmental impact.
- Continuous Hot Water Supply: With a 110-volt tankless water heater, you can enjoy a continuous supply of hot water in your RV. These units heat water as it passes through, ensuring that hot water is available whenever you need it. Whether you’re taking a shower, washing dishes, or doing laundry, you won’t have to worry about running out of hot water.
- Temperature Control: Most 110-volt tankless water heaters come with temperature control features, allowing you to set the desired water temperature. This level of control ensures that you can adjust the water temperature to suit your preferences and specific needs. It also helps prevent scalding accidents by maintaining a consistent temperature.

Disadvantages of a 110-Volt Tankless Water Heater for RV:
- Limited Flow Rate: One of the drawbacks of a 110-volt tankless water heater is its limited flow rate. These units typically have a lower flow rate compared to higher voltage models. As a result, they may struggle to provide hot water simultaneously to multiple fixtures in your RV. It’s essential to consider your hot water demands and the number of people using hot water at the same time.
- Lower Heating Capacity: 110-volt tankless water heaters have a lower heating capacity compared to their higher-voltage counterparts. While they can adequately handle basic hot water needs, such as showers and dishwashing, they may not be suitable for heavy-duty applications. If you require a high flow rate or need hot water for large appliances like a washing machine, a higher voltage model might be more appropriate.
- Slower Heating Time: Due to the lower voltage, 110-volt tankless water heaters may have a slower heating time compared to higher voltage options. It might take a little longer for the water to reach the desired temperature, especially in colder climates or when the incoming water temperature is low. Patience may be required while waiting for the hot water to flow.
