Supplied product data
Indirect Horizontal Unvented Cylinder
The Joule Cyclone Platinum 170L Horizontal Standard C is an indirect unvented cylinder designed to work with a primary heating loop. The supplied product information identifies compatibility with primary heating from a central boiler, heat pump or solar thermal loop.
Its horizontal format makes it suitable for installations where a conventional vertical cylinder is difficult to accommodate. It can be considered for under-bench, cupboard or plant-room installations where the available space is better suited to a horizontal cylinder.
Stainless Steel Construction
The cylinder body is manufactured from LDX 2101 stainless steel, with a coated mild-steel outer casing. The supplied construction specification is designed around a durable stainless-steel cylinder with a protective outer casing.
Thermal insulation is provided by dense PU foam, with a supplied heat-loss figure of 1.39 kWh/24h. This supports heat retention during periods when hot water is stored in the cylinder.
316L Stainless-Steel Heat-Exchange Coil
A single 316L stainless-steel coil provides the cylinder's primary heat-exchange function. The coil has a rated output of 20kW and a surface area of 0.57m², providing the specified heat-transfer capacity for the indirect system.
Heat-Exchange Specification:
1 × 316L stainless-steel coil · 20kW rating · 0.57m² surface area · 3.5 bar maximum primary pressure.
Immersion Heater Provision
The Joule Cyclone Platinum 170L cylinder includes provision for one immersion heater, specified at 3kW @ 230V. This provides an additional heating provision alongside the cylinder's indirect primary coil.
Pressure & Operating Specifications
The supplied technical data specifies a maximum mains water pressure of 10 bar and an operating pressure of 7 bar. The coil has a listed maximum primary pressure of 3.5 bar, while the supplied safety valve temperature is 90°C.
Ideal Applications
- Small to medium residential homes.
- Flats and apartments with limited vertical installation space.
- Systems heated through a central boiler, heat pump or solar thermal primary loop.
- Under-bench, cupboard or plant-room installations where a horizontal cylinder is preferred.
- Renovation and retrofit projects requiring a compact indirect unvented cylinder.
- Installations prioritising efficient heat exchange and controlled standby heat loss.
