Laundering clothes off grid has long been a problem. A modern high-speed spin washing machine uses about 1000 Watt hours for a complete normal cycle. This is not an issue to medium and larger systems but smaller systems will find that three or four loads per week may tip their requirement to a larger system.
ALL gas dryers unfortunately a use hot plate ignition to light each cycle and for safety control. When a cycle is to start the appliance heats a plate of metal until it is red hot this is called a hot surface ignition system and utilizes a 'glow bar' or 'glow coil'. The gas/air mixture is released and the flame starts another heating cycle. The heat cycle takes about 60 to 90 seconds each time. The way it works is that as power flows through the igniter it heats up and resistance increases. The oven gas valve is on the same circuit, when a specific amount of resistance is reached the oven valve is opened.
A modern propane fueled dryer with a normal load consumes approximately 180 Watt hours of power per load.
