Converting a Motorhome to a Gas-Free Setup
Many campervans and motorhomes still rely on LPG gas for heating, cooking and hot water. While this has traditionally been the standard approach, modern electrical systems now make it possible to operate a motorhome without using gas at all.
A gas-free motorhome replaces gas appliances with a combination of diesel heating and modern electrical systems, allowing the vehicle to operate using diesel fuel and battery power instead of LPG.
With the right electrical setup, a motorhome can comfortably run essential appliances including cooking equipment, refrigeration and everyday electronics.
Why Some Motorhome Owners Choose Gas-Free Systems
There are several reasons why motorhome owners are increasingly moving away from LPG systems.
No gas bottles
Removing LPG cylinders eliminates the need to carry, refill and store gas bottles.
Simplified fuel setup
Instead of relying on multiple fuels, many gas-free motorhomes use only diesel from the vehicle’s fuel tank along with electrical power from batteries.
Modern electrical capability
Lithium batteries, solar charging and inverter systems now provide enough power to support appliances that previously required gas.
Off-grid travel
A well designed electrical system allows motorhomes to operate comfortably away from campsite hook-ups.
What Changes in a Gas-Free Motorhome Conversion
Converting a motorhome to gas-free normally involves replacing gas appliances with alternative systems.
Common upgrades include:
• replacing gas heating with diesel heating systems
• installing lithium battery storage
• adding solar charging systems
• installing a powerful inverter system
• replacing gas hobs with electric or induction cooking
Each motorhome is different, so the conversion must be designed around the vehicle layout and electrical demand.
Electrical Power for Gas-Free Motorhomes
The key to a successful gas-free setup is a properly designed electrical system.
Modern motorhomes often use:
• lithium battery systems
• solar panels
• alternator charging systems
• inverter power systems
These systems work together to generate, store and manage electrical power throughout the vehicle.
High-quality power systems such as Victron electrical equipment allow motorhomes to operate reliably while travelling or parked off-grid.
Real-World Gas-Free Campervan Experience
At Keltie Campers Ltd, gas-free systems are not just theoretical.
Our own campervan has been running a fully gas-free setup for more than three years, using lithium batteries, inverter power and diesel heating.
The vehicle is regularly used for extended travel including winter trips to Spain and Portugal, as well as touring throughout the UK.
This real-world experience allows us to design electrical systems that perform reliably in everyday campervan use.
