Buffer Stores

Buffer Stores for Unvented Cylinders are designed to enhance the efficiency and performance of heating and hot water systems. They act as thermal energy storage units, helping to balance heat generation and demand — particularly in systems that combine multiple heat sources such as boilers, heat pumps, or solar thermal panels.

About Buffer Stores

Buffer Stores provide additional hot water and heating capacity by storing excess energy generated by the heating system. When the heat demand exceeds the boiler or heat pump’s immediate output, the buffer store releases the stored energy, ensuring a stable and efficient supply of heat and hot water. They are a key component in modern, energy-efficient heating systems, particularly those that use renewable energy sources.

Benefits

  • Improved system efficiency: Reduces short cycling and increases boiler or heat pump lifespan.
  • Energy optimisation: Stores excess heat for later use, reducing energy waste.
  • Stable water temperature: Provides consistent heating and hot water output.
  • Ideal for renewable systems: Perfect for use with solar thermal or heat pump systems.
  • Flexible integration: Compatible with unvented cylinders and multiple heat sources.

Applications

  • Properties using mixed energy sources (e.g., boiler + solar thermal).
  • Domestic and commercial heating systems with variable demand.
  • Installations requiring consistent water temperature and flow.
  • Systems with heat pumps or biomass boilers that benefit from stored thermal energy.

Key Features

  • High-quality insulation to minimise heat loss and improve efficiency.
  • Available in a wide range of capacities to suit various system sizes.
  • Durable steel or stainless-steel construction for long-lasting performance.
  • Compatible with both sealed and open heating systems.
  • Easy integration with unvented hot water cylinders.

Performance & Maintenance

Buffer Stores require minimal maintenance when installed correctly. Regular inspection of insulation, fittings, and temperature controls ensures optimal performance. When combined with unvented cylinders, they help maintain balanced system operation and provide improved comfort and energy savings.
