Maximize the efficiency of your renewable heating system with the Grant HPFR300C/BS 300 Litre Quick Recovery Cylinder. Specifically engineered to pair seamlessly with air source heat pumps—such as the Grant Aerona³ range—this high-performance unvented hot water cylinder delivers rapid heat transfer, minimal standing heat loss, and exceptional mains-pressure hot water throughout larger homes.

Product Features & Benefits

1. Purpose-Built for Heat Pump Efficiency

Heat pumps operate at lower flow temperatures than traditional gas or oil boilers. The HPFR300C/BS features an extra-large surface area heat exchanger coil. This enlarged transfer coil enables maximum heat absorption, reducing heat pump run times, lowering energy bills, and optimising overall system performance.

2. Rapid Hot Water Recovery

With a generous 300-litre capacity, this cylinder caters to high domestic hot water demands—ideal for properties with multiple bathrooms or larger families. Its quick recovery design ensures your household benefits from a continuous supply of hot water without long waiting times between uses.

3. Premium Stainless Steel Construction

Manufactured from high-grade, corrosion-resistant stainless steel, Grant Quick Recovery cylinders are built to last. The unit is encased in efficient thermal insulation to significantly minimise standing heat loss, ensuring compliance with strict UK building regulations.

4. Pre-Plumbed Advantage for Easier Installation

Designed with installer convenience in mind, the cylinder comes supplied with essential unvented safety components, including an expansion vessel, pressure relief valve, and a factory-fitted immersion heater for backup heating and thermal disinfection cycles.
