Can I fit an unvented cylinder where there isn’t the height for an upright one?
Where a horizontal unvented cylinder makes sense: lofts, eaves and anywhere height is restricted.
Choosing a World Heat Cylinders Horizontal Unvented Cylinder offers several distinct benefits, especially for challenging installations:
- Space Efficiency: Primarily, their horizontal orientation allows installation in areas with restricted headroom where a standard vertical cylinder would not fit. This makes them ideal for maximising unused spaces.
- Mains Pressure Hot Water: Enjoy powerful showers and fast-filling baths, as these cylinders deliver hot water at mains pressure to all outlets.
- High Flow Rates: Designed to provide excellent flow rates, ensuring consistent hot water delivery even when multiple taps are in use.
- Durable Stainless Steel Construction: We manufacture our horizontal unvented cylinders from high-quality Duplex stainless steel, offering superior corrosion resistance and ensuring a long, reliable service life.
- High-Performance Insulation: Featuring foam-injected zero ozone depletion potential (ODP) insulation, these cylinders minimise heat loss, thereby improving energy efficiency and reducing running costs.
- Versatile Capacity Range: Standard horizontal sizes run from 120 to 500 litres, and we build bespoke sizes to order.
