Choosing a Water Heater

When it comes to choosing a water heater for your RV, understanding the differences between tanked and tankless systems is crucial. Both types have their unique advantages and disadvantages, which can significantly impact your comfort and convenience on the road.

Tanked Water Heaters

Tanked water heaters, also known as storage water heaters, are the traditional choice for many RV owners. These systems store a fixed amount of hot water, typically ranging from 6 to 10 gallons, in an insulated tank. The primary advantage of a tanked water heater is its simplicity and reliability. Once the water in the tank is heated, it remains hot and ready for use until it is depleted. However, this system has some notable drawbacks.

One of the main disadvantages of tanked water heaters is the waiting time required to heat the water. Depending on the size of the tank and the heater's power, it can take anywhere from 20 to 60 minutes to heat the water to the desired temperature. This can be inconvenient, especially if you need hot water immediately. Additionally, once the hot water in the tank is used up, you must wait for the tank to refill and reheat, which can be a significant limitation during high-demand periods.

Tanked water heaters are also bulkier and heavier than their tankless counterparts. The need to store a large volume of water means these units take up more space and add extra weight to your RV, which can be a concern for those with limited storage or weight capacity. Furthermore, tanked water heaters continuously use energy to keep the stored water hot, which can lead to higher energy consumption and costs over time.

Tankless Water Heaters

In contrast, tankless water heaters, also known as on-demand water heaters, offer a more modern and efficient solution. These systems heat water as it flows through the unit, providing hot water only when needed. This on-demand heating method eliminates the need for a storage tank, resulting in several significant benefits.

One of the most appealing advantages of tankless water heaters is their ability to provide an endless supply of hot water. As long as you have a water source and sufficient propane or electricity, you can enjoy continuous hot water without the need to wait for a tank to refill and reheat. This is particularly beneficial for larger families or those who use a lot of hot water during their RV trips.

Tankless water heaters are also more compact and lightweight than tanked systems. Without the need for a bulky storage tank, these units take up less space and add less weight to your RV, making them an excellent choice for those with limited storage or weight capacity. Additionally, tankless water heaters are more energy-efficient, as they only heat water when needed, reducing overall energy consumption and costs.

However, tankless water heaters do have some drawbacks. They are generally more expensive upfront compared to tanked systems, which can be a consideration for budget-conscious RV owners. Additionally, tankless units often require more power to operate, which can be a challenge for RVs with limited electrical capacity.

Conclusion

In conclusion, the choice between tanked and tankless water heaters for your RV depends on your specific needs and preferences. Tanked water heaters offer simplicity and reliability but come with limitations in terms of waiting time, space, and energy efficiency. On the other hand, tankless water heaters provide an endless supply of hot water, are more compact and energy-efficient, but come with higher upfront costs and power requirements. By carefully considering these factors, you can select the water heater that best suits your RV lifestyle and ensures a comfortable and convenient experience on the road.
