  • G3 inlet group
  • Wholesome water expansion vessel
  • Factory fitted T&P valve
  • Over-temperature cut-out
  • Drain valves
  • Automatic air vent for coil

 

Cupboard sizing
The cylinder footprint is 600mm diameter. A potable expansion vessel will also need to be accommodated, as well as the G3 inlet valve, and safety relief discharge plumbing.

 

EnergyMaster HP300 features –

 

Suitable for both NIBE ground source and air source heat pumps, and for a typical house size. The cylinder comes complete with all necessary components including:

  • G3 inlet group
  • Wholesome water expansion vessel
  • Factory fitted T&P valve
  • Over-temperature cut-out
  • Drain valves
  • Automatic air vent for coil

 

Cupboard sizing
The cylinder footprint is 665mm diameter. A 50 litre (floor standing) potable expansion vessel will also need to be accommodated, as well as the G3 inlet valve, and safety relief discharge plumbing.

 

EnergyMaster HP500 features –

 

This cylinder option is well matched to larger NIBE ground and air source heat pumps and for use where the property’s water demand is greater. The cylinder comes complete with all necessary components including:

Buffer vessels

To boost heat pump efficiency Nu-Heat also supplies a 100-litre floor-standing buffer tank with a steel construction and white powder-coated casing that can sit beneath an EnergyMaster cylinder where sufficient height is available. The buffer tank has a 2-year manufacturer’s warranty.

 

BufferBox100™ features –

 

Suitable for use with the EnergyMaster HP and EnergyMaster HP Solar cylinders to expand heating system capacity and reduce heat pump cycling.

  • Cube shape for best space efficiency
  • ‘Passivated’ steel construction
  • White powder-coated casing
  • Four 28mm tappings
  • Two immersion heater tappings
  • Air vent
  • All fittings provided

 

Where there is sufficient height, the 300-litre EnergyMaster HP or 360-litre EnergyMaster HP Solar can be mounted on top of the buffer tank, otherwise it may be mounted separately.
