When living in an RV or travel trailer, the constraints on water resources, particularly hot water availability, are significant.
Water Heater Capacity: Most travel trailers and RVs are equipped with water heaters that typically hold 6-10 gallons of hot water. This small capacity means that showers need to be short. Traditional home water heaters can hold 40-80 gallons, providing longer stretches of hot water, but with an RV, once the 6-10 gallons are depleted, it will require time to heat more water.
Heating Method: The water heaters in RVs usually work on LP gas, electric, or both. LP gas systems heat up faster than electric heaters, but both take time to re-heat water once it's been expended. This time delay is important when considering multiple consecutive showers or additional hot water use immediately following a shower.
Water Flow Rate: Showerheads in RVs often have a water flow rate of about 2 gallons per minute. Therefore, a 6-gallon tank would only provide hot water for about 3 minutes at full flow before turning cold. Flow restrictors or water-saving shower heads can help extend this time slightly by reducing the water flow to about 1.5 gallons per minute.
Efficiency Tips: To maximize the limited hot water supply, consider installing an on-demand water heater if your RV or travel trailer model supports it. Additionally, utilizing a tankless propane water heater can help provide continuous hot water at a higher efficiency rate.
Conservation Practices: Implementing a naval shower strategy, where water is turned off while lathering, can conserve hot water for a longer shower experience. By doing so, users can stretch the available hot water beyond the typical 5-minute timeframe.
Alternatives and Supplements: Some mobile dwellers supplement their system with an external portable solar water heater or enjoy campground facilities when available to bypass the limitations of the RV's internal water heater, particularly for longer camping stays.
