World Heat’s 180 Litre U-Cyl Slimline Pre-Plumbed Air Source Heat Pump Cylinder with 25L Buffer is a space‑saving, high‑performance hot water and buffer solution for medium-sized homes on air source heat pumps. It combines a 180L slimline unvented stainless steel cylinder with an internal 25L buffer and neatly arranged components in a narrow footprint for tight plant rooms.
Key features:
Slimline pre‑plumbed and pre‑wired cylinder with primary pipework, controls, valves and safety devices mounted on the front for quick, tidy installation and reduced on‑site labour.
Integrated 25L buffer vessel provides system volume and hydraulic separation in the same casing, helping to stabilise flow, minimise heat pump cycling and support low‑temperature emitters such as underfloor heating and multi‑zone systems.
Duplex stainless steel construction with a 2 m² high‑efficiency heat pump coil, 50mm PU insulation and ErP‑rated performance for durable mains‑pressure hot water, low standing heat losses and a long 25‑year vessel warranty (with correct installation and maintenance).
