Horizontal Design for Space-Restricted Installations
The HORIZONTAL product configuration makes this Joule Cyclone Platinum cylinder suitable for applications where vertical clearance is restricted. Its horizontal format can be considered for under-bench installations, compact utility areas and plant rooms where a conventional vertical cylinder may not be practical.
With an empty weight of just 34kg, the unit also provides a relatively lightweight cylinder option for handling during installation.
LDX 2101 Stainless Steel Construction
The cylinder is manufactured from LDX 2101 stainless steel and features a coated mild steel outer casing. This construction provides a robust material combination for unvented domestic hot water storage.
The cylinder incorporates dense PU foam insulation and has a specified heat loss of 1.32 kWh/24h.
20kW 316L Stainless Steel Heat Exchange Coil
The Joule Cyclone Platinum 150L uses a single 316L stainless steel heat exchange coil for indirect heating. The coil has a specified rating of 20kW and a surface area of 0.57m².
The supplied specification lists the coil resistance as 45 bar. The cylinder has one heat exchanger and is designed for indirect primary heating systems.
Indirect Heating & Auxiliary Immersion
This cylinder is designed for indirect heating using a boiler, heat pump or solar thermal primary system. It also provides one immersion heater provision rated at 3kW @ 230V for auxiliary electric heating where appropriate.
Heating configuration: 1 × 316L stainless steel heat exchange coil rated at 20kW, plus 1 × 3kW immersion provision at 230V.
Mains Pressure & Operating Specifications
The cylinder has a specified maximum mains water pressure of 10 bar and an operating pressure of 7 bar. The supplied specification lists the operating temperature as 0°C and the safety valve temperature as 90°C.
The 0°C operating temperature value is retained exactly as supplied in the product specification.
Ideal For
- Small residential homes requiring compact hot water storage.
- Flats and apartments with limited vertical clearance.
- Under-bench installations and compact utility spaces.
- Plant rooms requiring a horizontal unvented cylinder.
- Boiler, heat pump and solar thermal indirect heating systems.
- Renovation and retrofit projects where horizontal installation is preferred.
- Installations requiring a 316L stainless steel heat exchange coil.
