How do hot water systems function in the caravan?

At one time, systems used in caravans were simple. They were often simple jugs , but then we witnessed the advent of pumps. They were hand pumps, and, later the foot pumps.

Although it’s not common to find these pumps manually nowadays, they’re still used on vessels. They were affordable, sturdy and efficient. But technology evolves and the times change with technology. Therefore, let’s go to the systems we use right now.

In essence, there are three components of your system. I’ll provide you with the details of each. These are:

Pumps for water
Water tanks
Water heaters

Pumps for water

The water pumping all around the unit is vital, as is pumping all the way around your system as well as pipes. The water is then pumped through pipes before being pumped in the system for heating water then it is taken out of the caravan.

In essence there are two types of water pumps:

Pressure pumps
Submersible pumps

Pressure pumps

The most expensive of you choose the other two options they are self-priming. They offer a more pleasant experience as they are more comfortable. Pressure pumps are ideal for showers since they allow for better flow of water.

Pressure pumps operate through several diaphragms inside the enclosure of the pump. They work by sucking up liquid from the water source, and push them through your pump and into your taps.

They cost more than other models and may be drained for a brief period of time without causing harm. The pumps themselves can be repaired should they fail as well as spare components, particularly for the most popular brands, are readily accessible.

Frost can cause damage to the pumps and they have to be cleaned out in winter. Another disadvantage is that, if things do not go as planned, they may result in flooding the caravan.

The advantages of pressure pumps

Fast and immediate water flow
Parts are available for repair
It is more difficult to overheat.

The disadvantages of pressure pumps

Submersible pumps

Submersible pumps are positioned within the tank, and they are responsible to ensure that the water flow is maintained. They run off of the 12v motor, and they move the water out of the tank, and in many cases , an aqua roll, until it is ready for use. They must be controlled by micro switches that are near the tap or the integrated.

It is the least expensive installation method and for the most part, it’s okay. They’re not ideal for showers but for the majority of situations, they’re good. One of the advantages is that in the event that you experience a leak, damage is less severe than those with pressure pump.

One thing you should not do is run the tank dry…make sure you’ve got enough water inside your tank. If you let it run dry for longer than 30 seconds can end up permanently damaging the submersible pump.

This means that you are able to refill your tank with water in the location you want to go rather than at a fix place.

If you are in a caravan with tanks fixed to the ground it is more restricted to the locations you are able to fill the tank up with water since you have to be near enough near the water source to be able to run an water hose.

In most cases, tanks can be located below in the floor of the vehicle, hidden in order to reduce the amount of area they normally use up. This technique has benefits. It’s one less thing to complete when arriving at your caravan’s location and the weight could aid in stabilizing your caravan as it is being pulled.

If the water that is coming out of the tank has a unpleasant scent or taste, the first thing to do is wash the tank and replace the water.

If you don’t use your vehicle, make sure that you drain the tank. It is possible to do this through leaving the tank open when you get to home, and then to completely drain the tank. It is crucial to not leave any water inside it while it is in storage, and especially during the winter seasons. This can cause damage to your tank to the level where you have to replace it.
