The Joule Cyclone Platinum 170L Twin Coil Solar Slimline Cylinder (TCEMVS-0170SFC) is a stainless-steel indirect unvented cylinder designed for solar-assisted domestic hot water systems. With a 175-litre stated capacity and 170-litre actual capacity, it features twin 316L stainless-steel coils rated at 19 kW and 15 kW, allowing solar thermal and a conventional primary heat source to be integrated into the hot water system.
Its slimline profile, dense PU foam insulation and LDX 2101 stainless-steel cylinder construction make it suitable for medium households and installations where available space is limited. With a maximum mains water pressure of 10 bar, 7 bar operating pressure and a stated heat loss of 1.9 kWh/24h, the Joule Cyclone Platinum provides a practical hot water storage solution for solar-assisted and indirect heating applications.

Twin-Coil Solar Hot Water Integration
The Joule Cyclone Platinum features two independent 316L stainless-steel heat exchangers, making it suitable for solar-assisted indirect hot water systems. Coil 1 is rated at 19 kW and Coil 2 at 15 kW, with each coil offering a 0.56 m² surface area and a maximum primary pressure of 3.5 bar.
This twin-coil arrangement provides separate heat-exchanger circuits for integrating solar thermal and another conventional primary heat source within the cylinder system.
Slimline Design for Space-Restricted Installations
The slimline cylinder profile is designed for installations where available plant-room or cupboard space is restricted. It is particularly suited to properties where cylinder depth and footprint need to be considered during system planning.
- 170-litre actual hot water capacity
- Slimline design for space-restricted locations
- Suitable for medium domestic households
- Empty weight: 49 kg
- Full weight: 214 kg
LDX 2101 Stainless-Steel Construction
The cylinder uses LDX 2101 stainless steel for its main cylinder construction, combined with a coated mild-steel outer casing. The twin heat exchangers are manufactured from 316L stainless steel.
This combination provides a corrosion-resistant stainless-steel cylinder and coil construction with a durable coated external casing for domestic hot water storage applications.
Dense PU Foam Insulation
The Joule Cyclone Platinum 170L uses dense PU foam insulation and has a stated heat loss of 1.9 kWh/24h. The insulation is designed to help minimise standby heat loss from stored domestic hot water.
Immersion Backup Provision
A single immersion provision is included, with a specification of 3 kW @ 230 V. This provides an electric heating provision for boost or backup applications alongside the cylinder's indirect heating arrangement.
Pressure & Temperature Ratings
The cylinder has a maximum mains water pressure of 10 bar and an operating pressure of 7 bar. The stated operating temperature is 60 °C, while the safety valve temperature is 90 °C.
