RV Refrigerators and Its Propane Usage

Traveling to remote areas such as oceans, mountains, and lakes require you to ensure that your foods always stay cold during the trip. While having a cooler will aid you with that, making ice can be a bit difficult especially when there is no fridge around.

Of course, you can have a stopover somewhere and buy some ice, but it is costly and time-consuming. To make your life easier while traveling, you should invest in a propane-using RV refrigerator. The best thing about a propane refrigerator is that you can use it anywhere. No need to find an electrical socket, its battery, and propane gas will provide you convenience even in remote locations.

How Does It Work?

  • In case you don’t know, a propane refrigerator is operated by its sealed piping system. Inside this pipe are a combination of water, hydrogen, and ammonia. The flame generated from the propane provides heat to the boiler that contains a solution of water and ammonia.
  • Once heated, it bubbles up via a percolator pump. Hot ammonia vapor was then released when this happens and it brings the water back to the boiler. Vapor rises into a condenser which transfers heat into the room air and then turns back to liquid thereafter.
  • This ammonia liquid will be drained down into an evaporator that contains hydrogen gas. The gas vaporizes the ammonia again and draws heat energy from the interiors.
  • After that, the hydrogen and ammonia mixture will be absorbed by the absorber chamber. In here, the ammonia will be dissolved again as water. This will lead to the release of hydrogen gas which will then goes back up to the evaporator once again.
  • The water and ammonia solution drains down to the boiler and will continue the cycle vice versa. Keep in mind that propane refrigerators are already available back in the 1930s. It became popular because of its easy convenience and for it being a great alternative when electric power is out of sight.

Propane Consumption of an RV Refrigerator

  • When it comes to propane consumption, you don’t need to worry about energy deficiency because most propane-made products are built with low emissions and fuel economy in mind. Propane refrigerators back from the 70s consume as half of the propane that’s used by refrigerators dated back in the 60s and earlier.
  • A 12 cubic feet of propane fridge consumes up to 1.5-lb. of propane gas when being used daily. Converting it into energy you get around 1,400 British thermal units every hour. However, if you opt for a smaller propane fridge, it will only consume less than 1-lb. of propane daily.
  • Larger units, however, consume more than 2-lb. of propane. While this is mostly true, it will also depend on the brand of the fridge.

Lowering the Propane Consumption of an RV Fridge

  • Can you actually lower its propane consumption? Probably! Below are some useful tips to make your RV fridge more efficient to use.
  • Level the fridge and the RV – leveling your fridge with your RV is the first thing you should do to make it operate more efficiently. Have an older model? A more precise modeling is fairly needed. However, newer models these days also need to be leveled properly to make it perform better. Using the fridge without it being properly leveled will result in permanent damage.

  • Cold foods come first – Fridge’s initial cooling down process often takes 4-6 hours. Best thing to do is let the fridge on for a day before putting all foods inside. When it comes to putting foods inside, make sure that cold foods come first. Cold foods play a vital role once they’re inside the fridge. Putting them first will make the unit work less, thus meaning less consumption for propane. You should also make it a habit not to overload your fridge too. Make some spaces in between each food to let the air circulate freely.

  • Use battery-operated fans for RV fridges – Most RV fridges today doesn’t come with built-in fans that can help circulate cold air inside. So investing in a battery-operated fan can be a big help when it comes to that. Put these fans at the bottom part of the fridge to let cold air circulate inside. Having proper air circulation also leads to reducing cool-down period up to 50%

  • Check the back of the fridge for obstructions – All of the work to make the fridge run is always found at the back of the fridge. So it’s always a good idea to check the back of the fridge from time to time and check for obstructions.

  • Do some routine maintenance – Doing routine maintenance ensures that your RV fridge will perform efficiently. Keep in mind that a properly maintained fridge is the key for a lower propane consumption. Take time to check your fridge if there are soot, rust, and any other items or hindrance that can affect its performance.

  • Keep its temperature low when it’s cold – In case you don’t know, the temperature outside the fridge also plays a vital role for its performance. So if it’s cold outside, turn down your RV fridge’s temperature level to make it consume less propane gas.


  • Having an RV refrigerator needs proper tending to make it perform more efficiently and effectively. Educating yourself and by following the tips above will get you ready for your road trip without worrying about RV fridge issues.

Tips to Make Your Concrete Odor-Free from Dog and Cat Urine

We all love our pets, even though they can create some little accidents sometimes. Sure you can clean a carpet easily in case they’ve urinated on it. But when it comes to your garage, it’s another side of the story. Listed below are a few tips to keep your garage floor odor-free from your pet’s urine.

Before anything else, cleaning urine out of concrete is a multi-step process. The good thing about the tips listed below is that it not only cleans urine odor, it also helps prevent further issues to happen.


  • Concrete may be sturdy to look at, but its porous nature is the real challenge here. Meaning, every liquid can enter in and sink deep down if not taken care off early. Even worse is the smell coming from the urine can lie dormant after it dries. And it can be re-activated when you pour another form of liquid into it. The best thing you can do is to perform deep cleaning to completely eliminate its smell. Sealing the surface after doing such will prevent further damage.

Preparing to Clean

  • Before you start scrubbing the floor, ensuring the entire floor is completely dust-free is the first thing you should do. Begin by using a push broom to sweep the floor away from any tiny particles and debris.

Locate Urinated Areas

  • Now that the floor is clear from any dust or any kinds of particles, it’s time to locate the spot where your pets peed at. Use a blacklight to scan the floor from any signs of pee. Once found, use a chalk to mark the spot for east spotting later. And now for the cleaning process!

Step 1: The Initial Clean

  • There are three types of concrete cleaners that you can use. Both of them are chemical and non-chemical. Let’s have a look at them!
  • Hydrogen Peroxide – This one can yield good results but can take a few days before you can see its effects. Take two drops of Dawn paired with two teaspoons of baking soda. Add them to two cups of hydrogen peroxide in a glass bowl. Mix well until the baking soda is completely dissolved. Once done, spray or pour the mixture on the urinated areas. The solution will soak deep into the concrete, completely eliminating urine. Repeat every 24 hours in between days until the smell is completely gone.

  • Trisodium Phosphate (TSP) – This one is a heavy duty cleaner that can get rid of urine traces and eliminates bacteria. You should be careful when handling such as TSP is known to create skin damage when in contact with skin. Wearing protective clothing and also goggles is advisable and keep your kids and pets away from the area when doing your cleaning operation. Make a mixture by adding ½ cup of TSP on a tub of hot water. Pour the mixture on the affected area and make sure that it doesn’t exceed three square feet or more since it evaporates quickly. Scrub the spot in a gentle manner and allow the mixture to sink in for at least five minutes. Apply more into the urinated are if needed. A very strong odor will be present when doing such so make sure to cover your nose. After doing such, rinse the affected area with hot water.

  • Vinegar – One of the most common and cheapest ways to clean the area is probably using vinegar. Mix two parts of vinegar into hot water and pour it on the affected area. This method is probably the most effective one as it works perfectly to fight urine odors. If TSP is too dangerous for you, then use this one as an alternative.

Step 2: Treating the Stain

  • Now that you’re done removing the odor out of the concrete, it’s time to seal the entire floor by using an enzymatic cleaner. Keep in mind that you only removed the “smell” of the urine and not the urine itself.
  • Enzymatic Cleaner – This type of cleaner comes in concentrated form and it’s known to break down uric acid that sinks deep down into the concrete. Make sure to follow the instructions carefully when using such to avoid any problems later on. To start, pour a portion of the cleaner into the stain and leave it for at least 10 minutes to let it soak in completely. Use a scrub to brush tough areas. After that, allow the floor to dry overnight. Now that the floor is completely dry, it’s time for the final step.

Step 3: Preventing Further Issues

  • For the final step, it’s time to seal the floor to prevent further issues by using a protective coating. Protective coating not only seals and protect, but it also prolongs the life of your floor too.
  • Concrete Sealer – When shopping for a concrete sealer, it’s best to opt for one that can protect your floor for the years to come. After purchasing one, follow the instructions carefully before starting. Rinse the floor thoroughly after applying and let it dry for at least 24 hours. Lastly, seal any leftover cracks using caulk to prevent urine or any kinds of liquid to enter in next time.
  • Results may vary depending on the type of sealer you used. Some sealers remain dry and clear while others will give your floor a glossy finish that can make it attractive. Keep in mind that result will not instantly show up in just a day. Some sealers will need at least 3-4 days before it completely cures.
