Product information

Description

The closed membrane heating expansion tank Nenurodyta Cornat AGH35, nominal 35 litre capacity, is designed to absorb thermal expansion in closed hot water heating systems and to help maintain stable system pressure. The tank features a diaphragm-type membrane that separates the air cushion from the heating fluid, ensuring efficient compensation of volume changes when the system heats and cools. This returned unit is suitable for integration with residential and light commercial boilers and heating circuits where reduction of pressure fluctuations and protection of valves, pumps and pipes are required.

Advantages

The diaphragm design provides reliable separation between the gas cushion and heating medium, reducing the risk of waterlogging and corrosion. With a compact cylindrical body and a standardized connection for heating circuits, the expansion tank is straightforward to install in typical boiler rooms and plant spaces. Its 35 litre nominal volume offers a balance between capacity and footprint for small to medium heating installations, helping to stabilise pressure and extend the service life of other system components.

Suitable for

  • Closed hot water heating systems in single-family homes
  • Small apartment heating circuits and compact boiler installations
  • Light commercial buildings with modest heating loads
  • System upgrades where pressure fluctuation reduction is required

Key specifications

  • Type: Closed membrane (diaphragm) expansion tank
  • Nominal volume: 35 litres
  • Purpose: Compensation of thermal expansion in hot water heating systems
  • Connection: Standard heating circuit connection (suitable for typical boiler interfaces)
  • Installation position: Vertical or as recommended by manufacturer instructions

How to use

Install the expansion tank on the return or feed pipe of the heating circuit in accordance with the boiler and system manufacturer’s guidelines. Before commissioning, ensure the membrane is intact, and set the pre-charge pressure of the tank to match the static pressure of the heating system when cold. After installation, bleed trapped air from the system and verify stable operating pressure during a controlled heat-up cycle. Periodic inspection of the tank, system pressure and pre-charge is recommended to detect loss of charge or membrane failure.

Usage recommendations

Use the expansion tank in closed hot water heating systems only. Match the tank pre-charge pressure to the system’s static pressure before first use, and follow regular maintenance checks to ensure membrane integrity and system protection.
