Let’s dive right in:

What is Aqua Hot in Rv’s?

Aqua Hot is a heating system that uses water to heat your RV. This type of heating is popular with RV owners since it’s easy to install, requires little maintenance, and, most importantly, does not require electricity or an electric connection! It allows you to keep warm in cold weather and saves on propane costs by adding more heat to your water and saving on propane use.

5 Rv aqua hot problems And Troubleshooting

The more you know about your aqua hot system, the better you’ll be able to troubleshoot it when problems arise! You can save money on repairs by being aware of potential problems and knowing how to fix them. So here are some of them:

Too Much Air Intake

Air intake is the amount of air your system pulls in to heat the water. If you’re experiencing problems with your Aqua-Hot system, there’s a good chance that your air intake is too high. Too much air can cause overheating and freezing, among other issues.

To check whether or not this is the case for you, measure the temperature of the air coming into your system using an infrared thermometer. You should see a reading between 30-40 degrees Celsius (or 86-104 degrees Fahrenheit).

If it’s higher than 40 degrees Celsius (104 degrees Fahrenheit), then this could be why you’ve been experiencing trouble with your Aqua Hot unit!

You’re Running Out of Water

If you check everything else and still need help figuring out why you’re running out of water, it’s time to review the pump. First, ensure that the pump isn’t malfunctioning by turning off both faucets and listening for a leak in your plumbing system.

If no leak is detected, remove the pump and inspect for any damage or debris causing it to malfunction. If there’s nothing wrong with your pump, you may have a faulty water inlet valve that needs replacing.

Suppose everything checks out okay except for one thing: Old age! Then it might be time for an upgrade!

You Have a Leak

Leaks are a common problem with RVs, and many places can leak. To check for leaks, you’ll need to do some detective work.

First, check your water heater. If it is leaking from the bottom of the unit or around its legs, it could signify that your water heater needs replacing. If your water heater has an internal leak, you’ll need to replace it as soon as possible before it causes significant damage to your rig by flooding or overheating other parts of your RV.

Next, check around all connections, including gas lines and vent pipes, for any signs of leakage, such as bubbling noises (this indicates bubbles forming under pressure).

Suppose you shower in the winter and the outside temperature feels colder than usual, but there are no obvious signs of leakage anywhere on the rig’s exterior.

This could be caused by poor insulation materials used during construction since many builders are becoming more aware of using environmentally friendly alternatives instead! In that case, you should check to see if any insulation has come loose at either end.

Your Aqua Hot Tank is Full of Water

You likely have a leak if your Aqua Hot tank is full of water. The first thing to do is check the tank for leaks and ensure it isn’t cracked. If there are no signs of damage or cracks in your tank, the seal around the heating element has become loose or popped out of place. If this is the case, re-seat it correctly and try again.

If nothing seems to work and you still have a full Aqua Hot tank every time you try to turn on your heat pump system, it might be time for a replacement unit!

Your Tank Is Full of Air

If your Aqua Hot tank is full of air, it will not heat. To fix this problem:

  • Check the pressure relief valve.
  • Check for a faulty seal.
  • Check for a defective component in your heating system.

If you cannot find or fix the issue on your own, call a technician and ask them to check out your system as soon as possible!


How do you reset Aqua hot?

If you have an Aqua Hot, there is a reset button on the front. The aqua hot reset button is usually green or red, depending on the model. You can find it by looking for a little plastic cover over the buttons, then pushing down on that cover to reveal them. Once you’ve found the button, press it until your tank turns off and cools down.

Do you need to winterize the aqua hot system?

No, you do not. The only thing that you need to do is drain the water from your hot water tank and make sure it’s empty before storing it. If there is any water in there, it could freeze and burst the pipes when temperatures get cold outside.

How long does it take Aqua hot to heat up?

It can take anywhere from one to two hours for the system to heat up. Some models also have a pre-heat feature that will turn on before you need hot water so that it’s ready when you are.


Knowing some common problems that could occur with your RV Aqua Hot system, as well as some tips on how to fix them yourself or find a professional service provider for assistance, we hope this article has helped make things clear for you!
