Product Description

Gledhill Stainless ES 200L Direct Unvented Cylinder – SESINPDR200

PLEASE NOTE: We can only deliver this cylinder to Mainland England addresses.

The Gledhill Stainless ES 200L Direct Unvented Cylinder SESINPDR200 provides mains-pressure hot water for family homes and properties with higher demand. Gledhill lists it as a 200-litre model, while its actual capacity is approximately 198 litres.

Two 3kW immersion heaters heat the stored water. Therefore, this direct cylinder suits properties that use electricity for hot water rather than a boiler-fed heating coil.

Gledhill makes the inner vessel from strong duplex stainless steel. In addition, 40mm insulation helps keep the stored water hot and reduce heat loss.

As an unvented cylinder, the Stainless ES takes its water supply directly from the mains. As a result, it can provide strong hot water flow to suitable showers, baths and taps. However, the property must have enough incoming water pressure and flow.

How Does a Direct Unvented Cylinder Work?

A direct cylinder uses electric immersion heaters to heat the stored water. It does not contain a primary heating coil for connection to a boiler.

Meanwhile, the unvented design takes cold water directly from the mains. As hot water leaves the cylinder, mains water replaces it. Therefore, the system does not need a traditional cold water storage tank in the loft.

Hot water performance depends on the incoming mains supply. As a result, your installer must test the available water pressure and flow before recommending an unvented cylinder.

Where Can You Use a 200L Direct Cylinder?

The Gledhill ES 200L direct cylinder may suit family homes, larger flats and properties with higher hot water demand. For example, it may suit a home with several occupants, more than one bathroom or multiple hot water outlets.

Because electricity heats the stored water, this model may also suit properties without a gas supply or suitable boiler connection.

However, every household uses hot water differently. Therefore, the correct cylinder size depends on several factors:

• The number of people in the property
• The number of bathrooms and showers
• The number and size of baths
• How often people use hot water
• The available mains water pressure and flow
• The time available to reheat the cylinder

For this reason, always ask a qualified installer to calculate the required capacity before ordering.

A qualified installer should calculate the required cylinder capacity before you order. The correct size depends on the number of occupants, bathrooms and hot water outlets.

Direct or Indirect Cylinder?

Choose a direct cylinder when electric immersion heaters will provide the main source of hot water. This option often suits electric-only homes and properties without a suitable boiler.

In comparison, an indirect cylinder contains a heating coil that connects to a boiler or another suitable heat source. It normally includes an immersion heater for backup use.

Therefore, check the property’s heating system carefully before ordering. Direct and indirect cylinders cannot always replace each other without changes to the system.

Benefits of Mains-Pressure Hot Water

An unvented cylinder can provide stronger hot water performance than a traditional gravity-fed cylinder. For example, it may improve the flow available at compatible showers, baths and taps.

In addition, the system does not need a cold water storage tank in the loft. This can free up space and avoid issues linked to an open loft tank.

However, the cylinder cannot improve a poor incoming mains supply. Your installer must test the pressure and flow before confirming that the system will meet the property’s needs.

Why Choose a Gledhill Stainless ES Cylinder?

Gledhill is an established UK manufacturer of hot water cylinders and heating products. The Stainless ES range offers a practical mix of value, strength and straightforward operation.

First, the duplex stainless steel inner vessel provides good resistance to corrosion. Next, the 40mm insulation helps reduce standing heat loss. Finally, the unvented design can provide mains-pressure hot water without a loft storage tank.

The package also includes key safety and control components. As a result, your installer receives the cylinder and its main unvented controls together.
