This range of electric mains pressure hot water cylinders comes with a 10 year warranty on the inner cylinder, and is backed by Rinnai after sales service and support.
Coiled range consists of:
Thermosiphon single and twin coil
Twin coil for connection to a wetback fire and a glycol solar system. Single coil if connecting to a wetback fire and/or a potable solar system. The single coil cylinder has an extra eco connection that can be connected to an open loop (potable) solar system, or a hot water heat pump.
Non-thermosiphon single coil
For connection to a closed loop solar system. Coil design spirals down and then wraps back up and around itself creating a coil within a coil. It is located at the very bottom of the cylinder to allow for maxim heat to be transferred to the water in the cylinder.
Non-thermosiphon twin coil
The coil design is created for use with glycol solar systems and connection to indoor boiler systems with radiators for home heating.
