I start the engine then the missus puts the clothes in the w/m, turns the taps on and presses start. One of us then makes a cuppa and we sit down with some cake or biscuits and read/do a crossword/surf the net/have a kip. When the w/m has finished the boss empties the w/m and hangs clothes up to dry (note it is an AUTOMATIC w/m)
Gibbo says we must be insane to heat water with batteries, could be but it ain't half relaxing.
ETA: Before someone points it out, yes we are heating water with the alternator rather than batts, although when batts are new we have been known to do a wash with engine off, crazy!
