Description

The Joule Invacyl Slimline In-Direct Unvented Cylinder 150 Litre is a compact, high-performance stainless‑steel hot water storage cylinder designed for unvented mains‑pressure systems. With 139.78 L usable capacity and a powerful stainless‑steel heat coil, it delivers reliable mains‑pressure hot water in space‑restricted installations. Dense PU foam insulation and corrosion‑resistant LDX 2101 construction minimise heat loss and maintenance, while a 25‑year warranty ensures long‑term confidence.

Key Features

  • Actual capacity: 139.78 L usable hot water.
  • Slimline stainless‑steel cylinder: LDX 2101 for corrosion resistance and durability.
  • Indirect heating coil: 316L stainless‑steel coil rated 16.33 kW with 0.76 surface area for efficient heat transfer.
  • High insulation: Dense PU foam to reduce standby heat loss (1.608 kW/24h).
  • Mains‑pressure operation: Max mains water pressure 10 bar; operating pressure 7 bar for strong delivery.
  • Immersion ready: 3 kW @ 230 V immersion specification.
  • Robust outer finish: Coated mild steel casing for added protection.
  • Low primary resistance: Coil resistance 0.2 bar; coil max primary pressure 6 bar for efficient circulation.
  • Safety & standards: Tested to BS EN 12897:2016; safety valve set to 90 °C.
  • Warranty: 25‑year warranty for long service life.

Ideal Use Cases

  • Family homes and apartments where space is limited but mains‑pressure hot water is required.
  • Renovation or new‑build projects needing a compact unvented cylinder.
  • Systems using boilers, heat pumps or solar thermal as the primary heat source.
  • Utility rooms or plant rooms with constrained footprints.
  • Properties requiring reliable, low‑loss hot water storage with high heat‑exchange capacity.
