Mastering Unvented Cylinder Safety

Learning Objective

Understand the safety controls and regulations for unvented cylinders.

What do you already know about the safety controls of an unvented cylinder?

Unvented Cylinder Basics

Unvented cylinders are a type of hot water storage system that operate at mains pressure.

Pressure Relief Valve

The pressure relief valve is a crucial safety component that releases excess pressure to prevent explosions.

Temperature Relief Valve

The temperature relief valve releases water if the water temperature exceeds a safe level.

Expansion Vessel

The expansion vessel accommodates the expansion of water as it heats up, preventing pressure build-up.

Thermostat

The thermostat regulates the water temperature, ensuring it stays within safe limits.

Overheat Thermostat

The overheat thermostat cuts off power if the water temperature exceeds a safe level.

Maintenance and Checks

Regular maintenance and checks are essential to ensure the proper functioning of safety controls.
