Converting Camper Heaters: Gas Option Explored

Converting your camper heater to gas is a great way to save money and stay warm. Gas heaters are a popular choice for campervan heating, as they are efficient, easy to use, and relatively affordable. They work similarly to diesel heaters, by combusting gas and using a heat exchanger to warm the air inside your van. The main difference is that gas heaters use LPG (liquefied petroleum gas) as their fuel source, which is typically cheaper and more readily available than diesel. However, it's important to note that gas heaters may be more challenging to find replacement fuel sources for while on the move.

When converting your camper heater to gas, you will need to consider the type of gas heater you want to install, the size of your campervan, the cost of installation and maintenance, and safety precautions. You may also need to modify your fuel storage system, depending on whether you choose a replaceable, refillable, or underslung gas cylinder setup. Additionally, it's important to consult a professional technician to ensure the safe and proper installation of your gas heater.

Gas vs diesel heaters

When it comes to heating your camper, you have a few options. The most common types of heaters are gas, diesel, and electric heaters. Gas heaters are typically powered by propane or butane, while diesel heaters use diesel fuel. Electric heaters, on the other hand, use electricity to generate heat. So, which type of heater is the best option for your camper?

Gas Heaters

Gas heaters are a popular choice for campers as they are typically more affordable and readily available than diesel heaters. They are also quieter and produce less noise, making them a good option for light sleepers. Additionally, if you already have a gas cooktop in your camper, you can tap into the existing gas line for your heater. However, one downside of gas heaters is that they can be more difficult to install, as they must be installed by a certified gas fitter and may require additional components such as a flue or exhaust system. Gas heaters also have higher fuel consumption and can be harder to find in remote locations.

Diesel Heaters

Diesel heaters, on the other hand, are known for their efficiency and reliability. They have lower fuel consumption than gas heaters and are often easier to find fuel for, even in remote regions. Diesel heaters can also be connected directly to your vehicle's fuel tank, eliminating the need for a separate tank. However, diesel heaters tend to be more expensive than gas heaters and can be noisier, particularly due to the pump that supplies diesel to the heater. Additionally, diesel heaters may require more regular maintenance and are typically larger and heavier than gas heaters.

Electric Heaters

Electric heaters are another option for heating your camper but are typically less commonly used as the sole heat source due to their high power consumption. They require a significant amount of electricity to run and are therefore not suitable for off-grid camping unless you have a large battery bank and solar panels to provide power. However, they can be a good supplementary heat source when hooked up to shore power or for occasional use.

Ultimately, the best type of heater for your camper will depend on your specific needs and preferences. Gas heaters are a good option if you prioritising cost and quiet operation, while diesel heaters are more efficient and may be more convenient if you already have a diesel vehicle. Electric heaters can also be an option, but they are typically not suitable as the sole heat source for off-grid camping. Additionally, it's important to consider factors such as the size of your camper, the climate you'll be camping in, and your budget when making your decision.

How LPG heaters work

LPG heaters are a popular choice for campervan heating. LPG, or liquified petroleum gas, is a mixture of propane and butane. LPG heaters work in a similar way to diesel heaters. LPG heaters produce heat through combustion and an internal heat exchanger. LPG heaters draw in air from outside the campervan, combust it in the heater, and expel exhaust gases outside through an exhaust system. The internal fan draws in air from inside the campervan, which circulates around the heat exchanger and leaves the heater warmed up.

LPG heaters are usually installed towards the rear of the vehicle and stored in a separate gas isolation locker. There are three methods for storing gas in a campervan: a replaceable gas cylinder bottle, a refillable gas cylinder bottle, and an underslung refillable gas tank. The first option is usually installed at the rear of the vehicle and stored in a gas isolation locker. The second option is also usually installed at the rear of the vehicle and stored in a gas isolation locker, with the additional feature of being refillable directly at the bottle. The third option is the most costly but offers the best fuel storage solution.

LPG heaters are safe to use, but it is important to follow the manufacturer's safety instructions. LPG heaters should be serviced and maintained regularly, and it is recommended to choose a professional technician for installation and maintenance. LPG heaters should not be used in bedrooms, bathrooms, or other small or badly ventilated rooms. It is also recommended to install a carbon monoxide alarm in addition to a fire alarm.
