Altecnic Remote Filling Loop with Gauge ALT-ST0035 with Free Standard Delivery in the UK

The Altecnic ALT-ST0035 Filling Loop is used to fill and pressurise domestic central heating systems or in apartment blocks to fill and pressurise the secondary heating systems of Heat Interface Units.

The Filling Loop Contains the following items:

  • An approved backflow prevention device (double check valve)
  • Temporary connecting pipe (a removable flexible hose)
  • Service valve (isolating ball valves)
  • 4 Bar pressure gauge

After the system has been filled and pressurised the service valves must be closed and the flexible hose disconnected and stored in a convenient and suitable place until it is required again.


The Altecnic ALT-ST0035 filling loop consists of a double check valve, a flexible hose with union connectors, sealing washers and a ball isolating valve with 4 bar pressure gauge.

The pressure gauge measures the pressure in the heating system and is especially useful when installed away from the boiler or when the boiler of HIU does not have an integral pressure gauge. Once the system is full and vented the flexible hose must still be removed as per the regulations.


Max Inlet Pressure: 10 bar

Min Inlet Pressure: 0.1 bar

Max continuous temperature: 85°c

Double Check Valve conforms to: BS EN 13959

Altecnic Product Code: ALT-ST0035
