FAQs about RV propane tankless water heaters
Q: Should you worry about your safety when using propane tankless water heaters?
A: Propane has a high density, so handling it should always be cautious. Natural gas dissipates, but propane gas may gather and set at the lowest point of the room. It’s best that you also install gas detectors.
Q: Do you need a special kit for propane tankless water heaters?
A: Propane water heaters resemble the natural gas water heaters, and that’s why most brands also include the kit. You can use it for altering the gas orifice and gas pressure regulator on your unit. However, the gas burner is the same, with propane water heaters only requiring more air for LP combustion.
Q: Are all gas tankless water heaters using natural gas?
A: If you have no clue about the correct answer, it’s time to go back to the drawing board. Joke aside, propane tankless water heaters come with the same features as the models fueled by natural gas. They also heat water on demand and don’t present standby heat loss (a common problem for the storage tanks). Since the water stays continuously in the tank, the risk for standby heat loss is quite high. Therefore, the energy is wasted even when you’re not using the hot water.
Q: Is it mandatory to have vents on a propane tankless water heater?
A: Going from electric tank to propane tankless water heater isn’t something to do overnight. Some planning is needed, but you can vent a high-efficiency unit right through the wall, using an affordable PVC pipe. Unlike the traditional storage tank water heaters, the propane tankless water heater doesn’t require venting through the roof. More often than not, the combustion fan exists exhaust horizontally from the unit. The vent options are many, with termination points and pipe cover, which solve the aesthetic problems as well.
Q: Can you use propane tankless water heater with well water?
A: It doesn’t matter the source of water for your RV/home when using a propane tankless water heater. If the water is harder, the risk for scale is going to be higher. However, modern tankless water heaters do inform the owner when it’s time for flushing the water heater. You should also look into using a water softener for reducing the scale, which may lengthen the periods between flushings.
