The hot water tank is only fired up when we need it for about 20 minutes. So the amount of gas consumed by the hot water is very little. The hot water boiler uses g per hour so tank of propane could keep us going for 91 hours in hot water.
Looking at the figures it would seem that a bottle of gas would last no time at all. In most cases you could burn off all your gas in a few days. Fortunately gas lasts a lot longer in real life. So when you start to use the gas for real then its much lower usage. We have found that a gas bottle will last weeks in the summer. We tend to use it for cooking mostly and if you want hot water we just have the boiler on for about 20 minutes and that is ample for a wash and more.
If I was to calculate how much gas we would use in a day I would have to lay down certain parameters to make it easier to calculate. So as you can see using the gas in the autumn with quite low temperatures I would be using just about a kilo of gas a day which would give me about 11 days from a bottle 11kg.
Obviously if you like the motorhome to be toasty and enjoy constant hot water then expect these figures to drop. In the summer the gas would go further. Your fridge will be working hard but it will never use more than the heater. So the cheapest time to travel as far as gas use goes would be in the warmer months. This would be when gas would last longer.
Obviously your fridge uses more gas in the summer but would not use anywhere near the amount of gas you need for heating in the colder months. When you start to use the gas you tend to be careful with it, its not cheap. Bottles are an expensive way to purchase gas which is why a lot of people have had LPG tanks fitted in their motorhomes which cost a lot less to fill than the removable bottles. So, if you use a lot of gas an LPG tank may pay for itself very quickly.
There are ways you can save on the amount of gas you use while on holiday in your motorhome or campervan. We tend to use campsites more than free parking so we get to use the campsite facilities so there are easy ways to cut down gas usage and use your electric hook up. Having a single ring electric hob is a great way to save on gas. Instead of heating things on the gas cooker just plug in the hob. A single ring hob will only use a few amps so should be fine to use on most campsites.
We put together some ideas for the motorhome kitchen. If like us you enjoy many cups of warm beverage then an electric kettle is a must if you are going to a campsite. A small camping one is suffice and will save you a fortune in gas. We use ours all the time. We have a small electric heater to use just to boost the temperature in the mornings. On really cold mornings I would recommend running the motorhome heating for a while. The built-in heating is usually designed to follow water pipes and also keeps your water tanks from freezing.
When free parking also known as wild camping or boondocking there is not usually an electric hook up so you have to run under your own steam so to speak. This is when you will put pressure on the gas and have to be careful with your usage.
Heat the motorhome up and then turn the heater low. You want to find the sweet spot where the heater is keeping the van warm and not getting any cooler. If you overheat the van you are just wasting gas.
Only put on the hot water boiler when you need it. Switch it off and only put it on about 20 minutes before you require hot water. We found that to be an ample amount of time for showers.
If you keep it on it will burn gas all day keeping the water at the temperature you have selected. Keep the fridge as low as it will go without defrosting. These factors include:. When cooking, for instance, setting the cooker on a high heat will consume gas faster than on a lower heat. Same if you cook for a longer period of time since this will consume more gas. How are you using the gas bottles?
Are you welding, making beer or filling balloons? The gas application is a major factor because it determines how much gas you need. Cooking a BBQ on the patio throughout summer will probably consume less than welding for that same amount of time. How long does a gas bottle last is based on its known energy content , which is based on the cylinder capacity and the energy content per unit of the LPG propane.
By dividing the hourly consumption of your gas appliance into the available energy content of the LPG gas bottle, you get the number of hours of how long does a gas bottle last. Patio gas will last 12 hours with a 35 MJ patio gas heater, based on a 9kg 20 lb patio gas bottle.
This is assumes using the HIGH setting and will last longer if turned down. A 9kg gas bottle patio gas will last about 15 hours, when cooking with a small 2 burner compact BBQ used on high. It will last even longer on lower settings or if only one burner is turned on. Patio gas 4. This is based on using the HIGH setting and will last longer if turned down. A small table top heater will last about 18 hours on a 4.
A 1-burner compact BBQ will last 22 hours on a 4. These durations all assume the burners are set on maximum. How long does a 13kg gas bottle last on a BBQ would be anywhere from about 9. Or, even easier, just use the 13kg chart below:. How long will a 20 pound propane tank last how long does BBQ gas last is determined by dividing the hourly consumption of your gas appliance into the available energy content of the propane BBQ gas tank, you get the number of hours how long does a gas bottle last how long does patio gas last.
