In domestic properties, there are two distinct types of hot water cylinders on the market. The increasingly popular and modern approach today is a pressurised 'unvented' cylinder vs. an older 'vented' cylinder. They both come in different sizes regarding the cylinder capacity, i.e., how much water they can store and heat.

Unvented Hot Water Cylinders

An unvented hot water cylinder stores water that is directly supplied from the mains water supply into the property. The hot water is subsequently heated using electrical elements (immersion heaters) within the cylinder or indirectly from a boiler (this is explained further down 'Indirect vs. Direct'). Due to the cylinder operating at mains pressure, they are capable of supplying multiple outlets with hot water at excellent flow rates. With your hot water being mains pressure, your hot water delivery will dramatically improve. The term 'unvented' derives from the cylinder not being vented to the open atmosphere.

They are an excellent selection if you require instant hot water with great flow rates in multiple bathrooms and kitchens.

Unvented hot water cylinders are extremely dangerous to fit yourself. You must have a qualified professional install & maintain your unvented cylinder. These units are extremely dangerous when installed incorrectly.

Indirect vs. Direct

Essentially, the difference between an indirect cylinder and a direct cylinder is how the water is heated internally within the cylinder. You have two options:

Indirect

The hot water is heated by an external power source, such as a gas boiler. These models usually have a backup immersion should the primary heating source fail.

Direct

Direct:- The hot water is internally heated by immersion heaters within the cylinder.
