Nu-Heat is pleased to extend the company’s range of hot water cylinders with the introduction of the EnergyMaster HP 215 and the EnergyMaster HP 255S. The cylinders have been developed specifically for use with Hitachi’s Yutaki single-fan heat pump.

The EnergyMaster HP 215 has been designed to contribute to high efficiency levels when used with the single-fan heat pump.

Main features of the EnergyMaster HP 215:

• 215 litre capacity
• All stainless steel construction
• 3 kW immersion heater for hygiene purge
• Can sit on top of the 100 litre buffer tank
• 2m² coil surface area

The coil is one-third smaller than in Nu-Heat’s larger cylinders. This is because the output of the single-fan heat pump is low enough for this to be practical. Additionally it has a 60°C flow capability.

To complement the HP 215, the HP 255S cylinder is a solar version, with some additional volume at the bottom of the cylinder which contains a solar coil. The solar volume has been designed for a single solar panel system.

Main features of the EnergyMaster HP 255S:

• 255  litre total capacity
• 60 litre dedicated solar volume – 195 litre heat pump volume
• All stainless steel construction
• 3 kW immersion heater for hygiene purge
• Can sit on top of the 100 litre buffer tank
• 2m² HP coil surface area
• 0.45m² solar coil surface area

Nu-Heat’s Senior Development Manager, Chris Weightman said: ‘It’s always exciting to release a new product. We’re delighted with results from both new cylinders and believe that they are great addtions to our heat pump offer.’

The cylinders will be available from March.
