How does the RV heating system work?

In the cold winter, people need to keep warm, and RVs also need to be protected. Now many consumers have begun to maintain their RVs. For some consumers, they hope to experience a more stylish RV life in winter, and this is inseparable from a weapon-the heater. Today we will take a look at this south wind Combi heating/hot water integrated system.

Whether it's a self-propelled RV or a towed RV, a heating system is required. Some RVs have built-in fuel heaters, and some RVs use gas heaters. For towed RVs, unlike self-propelled RVs, they don’t have a fuel tank. The best way is to use gas heating to heat and provide hot water. The Combi heater/hot water integrated machine produced by Nanfeng Company, which can discharge hot air and supply hot water with one device, is used by many people. So how does this heating system work?

It can be seen from the figure that the Combi heater/hot water integrated machine is basically located on the left and right sides of the caravan near the wall panels, which is convenient for maintenance and repair. The main equipment of this heating system is the Combi heater/hot water integrated machine. The equipment itself is very light and weighs about 15 kg. Different models may be slightly different. There are four types of gas alone, fuel alone, gas plus electricity, and fuel plus electricity.


Structure: This southern wind Combi heater/hot water integrated machine is marked with a serial number as a detailed structure. We have selected several important parts to mark and explain. The Combi integrated machine has two main functions. On the one hand, it pushes warmth into the RV. Wind heating, on the other hand, uses this system to provide hot water in the RV. This set of equipment is designed with 4 warm air outlets. Through the warm air ducts laid in the RV, the warm air is delivered to the RV compartment when the equipment is turned on, which plays a role in heating. In addition, the cold water injected from the water injection port can be heated from the hot water outlet pipe to the toilet shower, vegetable washing pool, etc. after being heated by the working equipment.

This heating system can be turned on in a single mode, for example, only heating water temperature is needed in a motorhome, or only warm air is sent. As for the power consumption, take the 4KW model all-in-one machine as an example, the maximum power is 4 kilowatts. When using liquefied gas (propane gas), only 160-320 grams of liquefied gas is consumed per hour. If a 5 kg can of propane gas is burned continuously for 24 hours, it can be used for about 15-30 hours. When it is turned on 8 hours late, at least 2-4 days of battery life can be guaranteed. If you use a more powerful 6KW model all-in-one machine, the energy consumption is relatively higher, but the heating effect is also better. As for how to choose, you need to choose the appropriate equipment according to the size of the interior space of the RV and the local climatic conditions. The heating efficiency of this equipment is very high. It only takes about 20 minutes to heat the water temperature from 15°C to 60°C.


The indoor temperature, air volume, hot water temperature adjustment and other functions can be adjusted through the control panel matched with this set of equipment, and the objects that need to be adjusted can be seen intuitively through the screen, which is convenient and quick.
