Description
The Joule Invacyl Slimline Direct Unvented Cylinder (180L) is a high-capacity, space-efficient stainless steel hot water cylinder engineered for unvented systems. Its slim profile delivers mains-pressure hot water to multiple outlets while occupying less floor or plant-room space. Designed for durability and low heat loss, it’s ideal for larger homes, multi-bathroom properties and renovation projects where space and performance matter.
Key Features
- 180-litre capacity for family-sized hot water demand
- Slimline design to maximise capacity in a smaller footprint
- LDX 2101 stainless steel cylinder for corrosion resistance and long service life
- Dense PU foam insulation (50 mm) for efficient heat retention (heat loss 1.7 kWh/24h)
- Two immersion heaters (3 kW @ 230 V) for rapid recovery
- Coated mild steel outer casing for protection and a neat finish
- Supports high mains pressure (up to 10 bar) with operating pressure 7 bar for reliable flow
- Safety temperature up to 90°C; tested to BS EN 50440:2015
- 25-year warranty for long-term assurance
Ideal Use Cases
- Larger residential homes and family properties with multiple bathrooms
- Multi-occupancy or shared properties requiring consistent hot water supply
- Renovation or retrofit projects where space is limited but capacity is needed
- Kitchens and bathrooms with simultaneous outlet use (showers, taps, appliances)
- Small commercial or office settings with moderate hot water demand
