I have an upright 400ltr static system at home. I heat my water as I transfer it to 8x 25ltr barrels. Then move them to my car. They stay warm right down till I use the last one between 2 and 3pm.
I built a cabin in my garden that houses the the tank, RO, and charging station for my trolley. I've also plumbed in an L5 propane heater. I just go out at 7.30am, open the door, turn on the gas, switch on the pump and stick the hose in a barrel and set a timer for 9mins (9mins/barrel). Then, whilst I'm getting ready my water is heating, and it's all done by the time I'm ready to set off.
