Vokera AquaFlow Twin Coil Solar Water Cylinder (Unvented)
Manufactured from high-grade corrosion resistant stainless steel, you can install this cylinder quickly and easily with a Zenith Solar thermal System and a system or regular boiler to benefit from solar thermal energy.
Internal secondary expansion via self-generating air gap means no expansion vessel required, or fully flooded cylinder with an expansion vessel.
With a balanced cold water supply point, no cold water feed tanks means a dry roof space.
Twin coil units are supplied with a low level immersion heater factory fitted and hard wired complete with surface mounted thermostat and a two-port motorised valve.
Twin coil cylinders are supplied with all mandatory valves and fittings and have two thermostats, upper for boiler heating and lower for Solar pre-heater.
No need for ‘sacrificial anode’ due to excellent anti-corrosion properties of Super-Molybdenum.
Secondary return facility on all units as standard.
