Unlike standard storage water heaters, these space-saving units will not deplete a significant amount of energy or require frequent refilling. Plus, their compact size makes them an ideal choice for RVers with limited storage space.

  • Type (gas or electric)
  • Adapters
  • Installation process
  • Warranty
  • Ease of use

Importance of a tankless water heater in an RV

An RV without a tankless water heater can be like a house without running water. If you’ve ever taken a cold shower or had to resort to using buckets of heated water for your campsite showers and dishes, you know how essential it is to have an adequate water heater.

An electric tankless water heater ensures that hot water is available on demand and in unlimited supply. This means no more waiting for the campground’s shared showers, or running out of warm water half-way through your shower!

Electric tankless heaters vary greatly in efficiency and features, so finding the right model for an RV requires careful consideration of power availability and usage requirements. It’s important to find one that can handle the demands of being used while travelling in remote locations when electrical outlets might not be accessible or reliable. Tankless heaters also tend to be more fuel efficient than traditional propane based systems, which makes them ideal for RVs with limited size and power sources such as solar energy. Finally, tankless heaters are compact and lightweight, making them easy to install in small spaces with minimal mounting hardware.

With this guide, you’ll be able to select the best electric tankless RV water heater for your needs and budget in 2021!

Features to Consider

Before buying a tankless water heater for an RV, there are certain features one should consider. These include:

  • Size: Tankless water heaters come in various sizes depending on the desired hot water output; it’s important to purchase the right size for your RV’s needs. The size of the unit also depends on how many outlets it can handle at once. Generally speaking, larger units will provide more hot water with fewer drawbacks than smaller models. It is also recommended to opt for a model with an inline thermostat so that you can easily adjust the temperature to suit your needs.
  • Power: Before selecting a tankless water heater, one must determine the amount of watts required by each outlet in order to operate it effectively and efficiently. Popular models such as Eccotemp FVI-12 are designed for RVs and generate up to 3 gallons per minute (GPM) of hot water at 115 degrees Fahrenheit (F). Determining the wattage output of each outlet is important when selecting its corresponding power source—whether 110 volts (V) or 30 amps (A).
  • Temperature Control: Most RV tankless water heaters have built-in temperature controllers for easy adjustment between 105 and 120 degrees F. Some may even offer up to 140 degrees F. Picking a model that has separate user-controlled settings allows you to adjust the temperature range according to your needs while ensuring ultimate safety and comfort during use.
  • Installation Type: While some electric tankless water heaters are suitable for both indoor/outdoor use without needing any professional installation assistance, others require routing through walls or floors which do require professional help in order to complete correctly and safely.

Flow rate

When selecting an electric tankless water heater for your RV, the flow rate of the water heater will determine how much hot water it can provide. Flow rate is typically expressed in gallons per minute (GPM). Smaller units provide up to 3 GPM, which is enough to meet the hot water needs of 1-2 people. In contrast, larger units provide up to 8 GPM and are suitable for large RVs with several bathrooms and two or more occupants. Units with a higher flow rate usually have faster recovery time – meaning that they require less time between uses of hot water to heat more of it.

When selecting your unit, consider its intended use – will you be running multiple fixtures at once? Will it need to provide unlimited hot showers? Based on this, you can determine the throughput (i.e., flow rate) you need from your electric tankless water heater.

Energy Efficiency

When selecting a Tankless Water Heater for your RV, it’s essential to consider the energy efficiency of the unit. The Energy Star Rating divides tankless water heaters into three categories—the more stars, the more energy efficient:

  • No star – These models are not rated. Be sure to compare several models in your budget range when considering one of these models.
  • One star – These models are the most basic and may not be suitable for all applications due to their low levels of efficiency.
  • Two star – Models with two stars offer a good level of efficiency and can reduce energy costs by up to 20%.
  • Three star – Models with three stars offer excellent levels of efficiency and can reduce energy costs up to 30%.
  • Four star – These models offer the best performance and highest efficiencies making them well worth the added expense for more demanding applications. Look for units that feature adjustable temperature settings which can help you further maximize your savings through improved accuracy and control.

Size and Power Consumption

The size of the tankless water heater and its power consumption are also important considerations. The size you need will depend on the size of your RV and how much hot water you require. As a general rule, larger tankless heaters tend to provide more hot water for better flow rate and fit larger RVs than smaller models.

The amount of power consumed by a tankless heater depends on several factors: its gas or electric burner, its heating elements, and other components within it. When comparing different models, look for one that features a high energy-efficiency rating, as this will help cut your utility costs in the long run.

Additionally, consider the cooler you live in when choosing an electric model since electric tankless heaters are usually less powerful in colder climates as compared to gas models.
