The Vaillant 300 Litre Heat Pump Cylinder Pre Plumbed is a high-capacity, energy-efficient hot water storage solution designed specifically to integrate seamlessly with Vaillant heat pump systems. It features advanced thermal injected polyurethane insulation combined with vacuum panels to minimise heat loss and maximise energy efficiency. Constructed from 100% recyclable stainless steel with an ultra-hard-wearing outer shell, this pre-plumbed cylinder comes with factory-fitted components for faster installation and reliable performance.
Key Features:
Superior Insulation & Low Heat Loss: Thermal injected polyurethane insulation paired with vacuum panels provides excellent thermal retention with very low standby losses of around 1.6 kWh per 24 hours, improving energy efficiency.
Optimised Heat Transfer with Large Integrated Coil: Equipped with a large-diameter smooth bore coil that ensures maximum heat transfer efficiency, reduces scale build-up, and increases hot water performance while reducing running costs.
Complete Pre-Plumbed System with Backup: Comes pre-plumbed and factory fitted with essential components including an immersion heater for emergency backup, expansion vessel, temperature and pressure relief valve, and a thermodynamically positioned sensor pocket for optimal system control.
