Installation & compatibility
The Joule Cyclone Platinum 250L Twin Coil Solar Cylinder Short C is an indirect unvented cylinder featuring two 316L stainless steel heat exchangers. The twin coil arrangement provides flexibility for systems using solar thermal alongside an auxiliary heating source. The cylinder supports a maximum mains water pressure of 10 bar and an operating pressure of 7 bar, while both coils have a maximum primary pressure rating of 3.5 bar.
Design & performance benefits
Twin High-Output Coils
Two 316L stainless steel coils rated at 18kW and 22kW provide dual heat exchange capability.
Stainless Steel Inner Cylinder
The cylinder uses an LDX 2101 stainless steel inner vessel for durable hot water storage.
Dense PU Foam Insulation
Dense PU foam insulation is used to help limit standing heat loss, specified at 2.30 kWh/24h.
High-Capacity Storage
The 247 litre actual capacity provides substantial stored hot water for higher-demand installations.
Additional installation features
Backup Immersion Provision
Includes support for one 3kW immersion heater at 230V.
Coated Outer Casing
A coated mild steel outer casing provides a robust external enclosure for the cylinder.
Tested to BS EN 12897:2016
The cylinder is tested to BS EN 12897:2016 and has a 1-year warranty.
Ideal for
The Joule Cyclone Platinum 250L Twin Coil Solar Cylinder Short C is ideal for larger family homes, light-commercial properties, solar thermal systems, renovation projects and new-build installations requiring substantial hot water storage. Its twin-coil configuration makes it particularly suited to systems requiring solar thermal and auxiliary heating flexibility, while the LDX 2101 stainless steel inner cylinder and 316L stainless steel coils provide a robust solution for indirect unvented hot water storage.
