Product Description

Gledhill Stainless ES 150L Direct Unvented Cylinder – SESINPDR150

Please note: We can only deliver this cylinder to mainland England addresses.

The Gledhill Stainless ES 150L Direct Unvented Cylinder stores and heats hot water for modern homes with moderate hot water needs. It has a nominal size of 150 litres and an actual capacity of around 149 litres.

This direct cylinder uses two 3kW immersion heaters to heat the stored water. Therefore, it suits homes that need an electric hot water cylinder rather than one connected to a boiler.

Gledhill makes the cylinder from strong Duplex stainless steel. This material helps protect it against rust and corrosion. In addition, 40mm insulation helps keep the water hot and reduces heat loss.

As an unvented cylinder, this model supplies hot water directly from the mains. As a result, it can provide good water pressure at showers, baths and taps. However, the property must have suitable mains water flow and pressure.

What Comes with the Cylinder?

• 2 x 3kW immersion heaters
• 1 x expansion vessel

These parts help your installer complete a safe and correct unvented hot water system. However, the installer may need extra valves, pipework and fittings to suit the property.

Where Can You Use a 150L Direct Unvented Cylinder?

The Gledhill ES 150L direct cylinder may suit flats, family homes, annexes and other properties with moderate hot water needs. For example, it may suit a home with several hot water outlets or more than one person using hot water each day.

Because this is a direct cylinder, the immersion heaters heat the water. It does not use a boiler-fed coil. Therefore, it can work well in properties with electric heating or no gas supply.

However, every home uses hot water differently. The correct cylinder size will depend on the number of people, bathrooms, showers, baths and taps in the property. For this reason, always ask a qualified installer to check the required cylinder size before you buy.

Why Choose a Gledhill Stainless ES Cylinder?

Gledhill is a well-known UK hot water cylinder maker. Its Stainless ES range offers a good mix of value, strength and simple operation.

First, the Duplex stainless steel body gives the cylinder strong protection against corrosion. Next, the 40mm insulation helps keep the stored water hot. Finally, the unvented design can provide better hot water pressure than a basic gravity-fed system.

The Gledhill ES 150L cylinder also comes with key safety parts. As a result, your installer can source the main cylinder and its main controls in one package.
