World Heat’s 250 Litre U-Cyl Pre-Plumbed Air Source Heat Pump Cylinder with 50L Buffer is a high‑capacity, all‑in‑one hot water and buffer solution for larger homes on air source heat pumps. It pairs a 250L unvented stainless steel cylinder with an integrated 50L buffer and factory-fitted components to keep installations fast, neat and consistent.
Key features:
Pre‑plumbed and pre‑wired cylinder with primary pipework, controls, valves and safety devices mounted on the unit for reduced installation time, labour and on‑site errors.
Integrated 50L buffer vessel adds essential system volume and hydraulic separation, helping to stabilise flow, prevent short cycling and support underfloor or multi‑zone heating layouts.
Duplex stainless steel construction with a large high‑efficiency heat pump coil and thick polyurethane insulation, delivering durable mains‑pressure hot water, strong heat transfer, low standing heat losses and a long manufacturer vessel warranty.
