How RV Dwellers Maintain Heat and Electricity
RV living presents a unique set of challenges, especially when it comes to providing heat and electricity. The living conditions in recreational vehicles (RVs) can vary widely, depending on the type of RV and the level of amenities it offers. This article explores the various methods used by RV residents to ensure they stay warm, illuminated, and powered for their daily activities.
Basic Power and Heating Solutions
Most RVs use 12-volt battery power for lighting and propane LP gas to generate heat and hot water. These systems are efficient and relatively straightforward, providing a basic level of comfort for RV residents. For extended battery life and less reliance on propane, some RVs incorporate inverters that convert the battery power to AC for devices like TVs and microwaves. However, these inverters can drain the battery quickly, which necessitates a reliable power source.
Generating Additional Power
Without an external power hookup, RVs may use built-in or external generators to handle heavier electrical loads such as air conditioners, electric heaters, microwaves, and fridges. For extended periods of off-grid living, most RVs must eventually be plugged into an electrical supply to recharge their batteries. Motorhomes, in particular, can recharge their batteries using the engine while driving, harnessing the vehicle's energy to power the coach.
Additionally, motorhomes with diesel engines can use diesel as a heating and cooking fuel. Some RVs, like mine, feature a battery-powered forced-air furnace that burns propane, providing a cost-effective and efficient solution for dry camping under external hookups. However, during the colder months or in the absence of external hookups, electric heaters can be used to save propane.
Off-Grid Solutions
For those who prefer an off-grid lifestyle, diesel heaters are particularly useful. They are cheap, efficient, and run off the house batteries, which can be charged by a caravan park supply or solar panels. In my setup, I run a 600-watt system with two 110ah Pb crystal AGM batteries and a 12V compressor fridge. This combination allows me to minimize propane usage, as just one 4.5kg tank of LPG suffices for cooking for months at a time.
To power additional devices and appliances, I use an MPPT controller to manage the solar panels and charge the batteries efficiently. With a 3000w pure sine wave inverter, I can even power my coffee machine, ensuring I maintain my daily routines even when off the grid.
Self-Contained RVs
Our motorhome is designed to be self-sufficient with re-fillable gas tanks for heating and cooking. Power is provided by a 12-volt system, and two 120 Ah SLA batteries are charged by solar via an MPPT controller. While we may face some challenges during long periods of winter darkness, the setup allows us to be comfortable even without external hookups.
Conclusion: RV living requires careful planning and the right equipment to stay warm, powered, and comfortable. Whether through traditional propane and battery systems, inverters, or off-grid solutions like diesel heaters and solar panels, there are multiple ways to ensure a cozy and convenient living environment while on the road.
