Another great thing about them is that the heaters are easy to install. You should not have much trouble with them if you go through the instructions provided carefully. Though, there are some errors aside from this that the user can run into.

We will be using this article to provide you with some common problems that you can get on an RV tankless water heater and steps to fix them. This should help in fixing them so that you can have a fun and enjoyable trip.

RV Tankless Water Heater Problems

  1. Heater Switching Off Between Showers

If you are someone who has been using these tankless water heaters for some time now. Then it is highly likely that the unit installed in your vehicle has gotten old. All water heaters have a minimum flow rating given to them. This indicates that as long as the water flowing through it is below this pressure, you will be provided with warm water.

Though, the value is quite low for older models. This means that once the pressure increases, your heater will fail to heat the water. It will then keep on switching off and give you trouble. One simple method to fix this is by turning off your tap a little.

This will decrease the pressure so that you can continue using hot water. Although, the solution might not be for everyone. Considering this, you should purchase a new unit and get it installed.

Newer tankless water heaters provided a much higher minimum rating for the pressure which takes out the worry of having to lower it. You can easily use your shower and taps without thinking about how much pressure you are using.

It is still important that you go through the specifications for the product beforehand to ensure there are no issues with it. There are many guides and articles provided online that allow users to find the best heater for their vehicle. Going through them should help you out significantly.

  1. Water Keeps Getting Cold

Another common problem that users can get is that the water they are getting from the heater keeps getting cold. In this case, you should note that water heaters take some time to warm up before water can properly start getting heated up.

Keeping this in mind, the user should leave their tankless water heater switch on along the tap for a few minutes before getting into the shower.

You will then note that the water now comes out consistently without getting cold in between. Though, sometimes the exchanger in your heater can get damaged. This is the part responsible for heating the water. If this happens, then the user will have to get it replaced with a new one.

Contact a specialist nearby you to have them check your heater. They should then be able to install the new part for you or they might even fix the old one. Once this is done, you can then start using your tankless water heater without any issues with it.

  1. No How Water Coming Out

Sometimes people might notice that their water heater is giving out no hot water. This usually happens when you have a lot of appliances connected to the unit. You should remember that there is a limit to the amount of water your heater can warm up at a time. You can try switching off any additional taps and only use a few of them at a time.

If this fixes your problem then there are mainly two options for you. Either purchase a new unit that can provide you with a much larger capacity of water. Alternatively, you can even think about using two heaters in your vehicle.

Though this can consume a ton more electricity so keep that in mind. For users who take several people with themselves on their trip can find this as a better solution.
