Joule Cyclone Plus Direct Standard Unvented Hot Water Cylinder 120L 150L 180L 210L 250L 300L
Joule Cyclone Plus Direct Standard Unvented Hot Water Cylinder 120L 150L 180L 210L 250L 300L
The Joule Cyclone Plus Direct Standard is a full-diameter direct electric unvented hot water cylinder available in 120 L, 150 L, 180 L, 210 L, 250 L and 300 L capacities. Where the Slim range is built for tight spaces, the Standard range is built for properties with adequate cupboard or plant room width — and where maximum capacity per pound spent matters. Constructed from Duplex stainless steel with 316L stainless fittings and coil, it delivers full mains-pressure hot water to single or multiple outlets and carries a 25-year cylinder warranty. The coil-in-coil heat exchanger and CFC/HCFC-free foam insulation (ODP 0, GWP 1) provide efficient heating and minimal heat loss.
The cylinder vessel is Duplex stainless steel with 316L grade stainless fittings and coil — the same food-grade alloy used in marine and pharmaceutical equipment. This combination offers outstanding corrosion resistance and a long service life across the full range of UK water conditions.
The coil-in-coil smooth-tube heat exchanger gives the Cyclone Plus range its high recovery rate compared to standard single-coil designs. The smooth bore is also inherently more resistant to limescale build-up, extending service intervals and maintaining heat-transfer efficiency over the cylinder's life.
Every plumbing connection on the Cyclone Plus Standard is positioned at the front of the unit. This allows the cylinder to be sited against a wall or in a cupboard corner with no rear or side access required, reducing installation time and giving the engineer more flexibility in tight plantrooms.
Dense polyurethane foam insulation with an ODP of 0 and GWP of 1 minimises standing heat loss between heating cycles. This directly reduces running costs — particularly relevant on direct electric systems where heat loss is entirely borne by the electricity bill.
The Cyclone Plus is finished in a white outer casing with a grey polycarbonate T&P safety cover. The clean finish suits utility rooms and visible plant areas, and the grey cover provides clear visual identification of safety components without the need for labelling.
The complete unvented inlet control group is included: strainer, pressure-reducing valve, non-return valve, expansion relief valve, expansion vessel and hose, tundish, T&P relief valve, and dual cylinder thermostat with high-limit cut-out. No separate kit purchase required — all components are from leading branded manufacturers.
The Standard range extends to 300 litres — suitable for households of 4–5+ people or properties with multiple bathrooms requiring high simultaneous hot water demand. The larger capacity sizes (250 L, 300 L) are ideal for HMOs, small commercial premises and developer-built family homes.
| Parameter | Details |

| Diameter (approx) | ~545 mm (standard — wider than the 475 mm Slim range) |
| Immersion heater | 3 kW Incoloy @ 230 V (factory-fitted); Titanium / 6 kW optional |
| Max mains working pressure | 10 bar |
| Operating pressure (T&P) | 7 bar |
| Cylinder material | Duplex stainless steel |
| Fittings and coil grade | 316L stainless steel |
| Heat exchanger | Coil-in-coil smooth-tube |

| Outer casing | White with grey polycarbonate T&P safety cover |
| G3 kit included | Yes — full inlet control group, exp. vessel, T&P valve, tundish |
| Cylinder warranty | 25 years (controls/components: 1 year) |
Is the Cyclone Plus Direct Standard the same as the Cyclone Platinum?
Can I upgrade to a 6 kW or Titanium immersion heater?
How does this compare to the Slim range for a 300 L installation?
Is an annual service required?
Can this cylinder be used with a solar PV diverter?
