Twin coil systems, save money on power in summer using solar water heating through the standard coil, and in winter heat the water by the wetback fire using the thermosiphon coil.
The thermosiphon coil for wetback has the water circulating through a coil inside the cylinder by a thermosiphon effect, i.e. warmer water rises and cooler water falls, creating a natural flow. This means there's no need for a pump to circulate the water, you can still heat your water even if there's a power cut.
