World Heat’s 150 Litre U-Cyl Slimline Pre-Plumbed Air Source Heat Pump Cylinder with 25L Buffer is a space-saving all‑in‑one hot water and buffer solution for smaller homes on air source heat pumps. It combines a 150L slimline unvented stainless steel cylinder with an internal 25L buffer and factory-fitted 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 stainless steel buffer vessel adds system volume and hydraulic separation in one casing, helping to stabilise flow, reduce cycling and support low‑temperature emitters such as underfloor heating.
High‑quality duplex stainless steel construction with a 2 m² high‑efficiency 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 annual maintenance).
