The Vaillant 250 Litre Heat Pump Cylinder Pre Plumbed offers an efficient and robust hot water storage solution specifically designed to integrate seamlessly with Vaillant heat pump systems. Constructed from 100% recyclable stainless steel with a durable outer shell, it features advanced thermal injected polyurethane insulation combined with vacuum panels to minimise heat loss and maximise energy efficiency. This model comes pre-plumbed with essential components including a 25-litre expansion vessel, immersion heater for emergency backup, and a thermodynamically positioned sensor pocket for optimised system control and easy installation.
Key Features:
Optimised Heat Transfer and Large Capacity: Equipped with a large diameter, smooth bore coil that ensures maximum heat transfer efficiency, reduces scale build-up, and supports fast, efficient hot water delivery suitable for medium to large residential demands.
Superior Insulation with Low Heat Loss: Thermal injected polyurethane insulation combined with vacuum panels provides some of the lowest standby heat losses in its class (approximately 1.4 kWh/24h), enhancing energy savings and maintaining water temperature for longer periods.
Complete Pre-Plumbed System: Includes a factory-fitted 25-litre expansion vessel, immersion heater for emergency backup, temperature and pressure relief valve, and a three-way motorised valve—all pre-installed for straightforward setup and compliance with building regulations.
