World Heat’s 300 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 300L unvented stainless steel cylinder with an integrated 50L buffer and factory‑fitted components to deliver quick, tidy and consistent installations.
Key features:
Pre‑plumbed and pre‑wired cylinder with primary pipework, controls, valves and safety devices mounted on the front of the unit to cut installation time, labour and on‑site errors.
Integrated 50L buffer vessel provides essential system volume and hydraulic separation, helping to stabilise flow, reduce short cycling and support low‑temperature emitters such as underfloor and multi‑zone heating.
Duplex stainless steel construction with a large 3 m² heat pump coil and thick polyurethane insulation, providing durable mains‑pressure hot water, strong heat transfer, low standing heat losses and a long manufacturer vessel warranty.
