Product information

Description

Ferroli FB 800 is an 800-litre indirect-free central heating buffer tank designed to store thermal energy from boilers, heat pumps or other heat sources. The tank has no internal heat exchanger coil, providing a simple and reliable storage volume that smooths system cycling and helps maintain consistent heat delivery. Factory-fitted insulation reduces standby losses while 6/4‑inch central heating connections ensure compatibility with standard pipework in residential and light-commercial installations.

Advantages

The design without an internal coil increases usable volume for thermal storage and simplifies maintenance. Built-in insulation lowers heat losses and improves overall system efficiency. Standard 6/4‑inch heating connections make hydraulic integration straightforward, and the large 800 L capacity reduces boiler short-cycling and supports better matching of intermittent heat sources with demand.

Suitable for

  • Residential central heating systems with boilers or heat pumps
  • Light-commercial heating installations requiring bulk thermal storage
  • Multi-source systems combining boiler, solar thermal or biomass
  • Systems where cycle stabilization and reduced start/stop events are desired

Key specifications

  • Nominal volume: 800 litres
  • Type: indirect-free buffer (no internal heat exchanger coil)
  • Heating connections: 6/4‑inch central heating ports
  • Insulation: factory-fitted thermal insulation
  • Application: central heating thermal storage for residential and light-commercial use

How to use

Install the Ferroli FB 800 in the central heating circuit according to local plumbing and heating regulations, ensuring the 6/4‑inch connections align with the system piping. Connect the buffer tank between the heat source(s) and distribution circuit so it can store excess heat and return it when needed. Commission the system with appropriate control logic and safety devices (expansion vessel, pressure relief valve, circulating pumps and temperature sensors) to manage charging and discharging cycles. Regular visual inspections of insulation, connections and fittings are recommended.

Usage recommendations

To maximize performance, match the buffer volume and control strategy to the heat source characteristics and building load. Use the Ferroli FB 800 to reduce short-cycling of small boilers or intermittent heat sources, and ensure correct hydraulic balancing and control setpoints for efficient operation.
