What types of unvented cylinders are available?

Depending on the existing plumbing in the building, you might require a certain type of cylinder. At City Plumbing, we have a wide variety of unvented cylinders designed to heat your water supply in the most efficient way.

We supply both direct and indirect unvented hot water cylinders to suit both purposes.

What is the difference between direct and indirect unvented cylinders?

A direct unvented cylinder uses an electric immersion to produce heat and won’t work with a gas or oil boiler. These types of cylinders are often found in modern homes that are more fuel efficient and eco-friendly.

An indirect unvented cylinder has a coil that runs through the middle of the tank. This is heated by an external source and then imparts its heat onto the water in the tank. This water is normally used for washing and showering but would not be considered safe drinking water.

Direct unvented cylinders for sale

For those looking for high-performing direct unvented hot water cylinders the Gledhill Esprit 120 Litre Unvented Direct Cylinder fits the bill. With a 25-year warranty, this quality cylinder is manufactured from 100% recyclable duplex stainless steel.

This cylinder delivers mains pressure hot water and enables high flow rates for showers and baths without any need for an additional pump. A 40mm thick HCFC free insulation reduces any chance of heat loss, making this a modern solution to your hot water supply.

Indirect unvented cylinders for sale

For those in need of indirect unvented hot water cylinders the Gledhill Stainless Steel 210L Indirect Unvented Cylinder is a strong contender. Its additional post-weld treatment means it is designed for longer use and durability.

A corrugated tube coil heat exchanger connects to a conventional boiler to heat the cylinder of water, providing quicker recovery times than can be achieved by plain tube coils. This makes for a better performance and traps in a larger amount of heat for longer warmth. Manufactured from 100% recyclable duplex stainless steel with the latest automated welding procedures, this cylinder is strong and sturdy.
