The McDonald STEELflow Indirect Unvented Heat Pump Cylinder is manufactured from duplex stainless steel, and specifically designed for use with either air source or ground source heat pumps. It can also be used with gas system boilers using Priority Domestic Hot Water (PDHW).

These cylinders have a large corrugated high efficiency indirect heat exchanger to ensure optimal heat transfer at lower flow temperatures. The coil’s corrugated design provides high heat transfer and flow rates from the heat pump, with faster recovery times than plain coils due to the increased surface area.
