Features and Benefits: Vaillant uniSTOR Pure HP 300 Litre
Faster Hot Water: The large internal coil heats your water fast for low flow temperatures (50°C–55°C) for high heat transfers, fast re-heat times, and to give you the best heat pump COP (Coefficient of Performance).
Top-of-the-Line 300L Unvented Cylinder: This large capacity unit provides plenty of mains-pressure hot water to run several power showers, baths, and taps at once without any loss of pressure.
Low Standing Heat Loss: High density injected polyurethane foam insulation keeps the standing heat loss of the water to the bare minimum. This gives the remaining heat in the water as little standing loss of energy as possible.
Fits Tight Spaces: Clearly labelled pipework connections to the front of the unit means your plumber can work faster, saving you money on installation costs.
Patented Stackable Buffer Compatible: Vaillant’s purpose built stackable buffer cylinders allow them to be stacked either directly above or below to save floor space in areas that are too small or over crowded.
Thermal Sensor Pockets: Gives accurate temperature readings and communication with the Vaillant heat pump controller.
Boiler Tank 25-Year Guarantee: Protecting the stainless steel inner vessel from corrosion and backed up by Vaillant's established service network right across the UK.
