AquaCyl Cylinder - Twin Coil Installations  Ref: AquaCyl
An Indirect coil from the solar collector heats water in the twin coil cylinder to feed the DHW demand at the tap or shower. During the summer months heat from the solar collector alone is adequate to deliver temperature. In months when energy from the sun is weaker a second coil heated by a system or open vent boiler boosts the heat of water in the cylinder tank to the required temperature.
