Product Description

Gledhill Stainless ES 250L Direct Unvented Cylinder – SESINPDR250

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

The Gledhill Stainless ES 250L Direct Unvented Cylinder stores and heats water for larger homes with high hot water demand. It has a nominal size of 250 litres and an actual capacity of around 248 litres.

Two 3kW immersion heaters heat the stored water. Therefore, this direct cylinder suits properties that need a large electric hot water cylinder instead of a cylinder connected to a boiler.

Gledhill makes the cylinder from strong Duplex stainless steel, which helps resist rust and corrosion. In addition, 40mm insulation reduces heat loss and helps the stored water stay hot for longer.

The unvented design takes its water supply directly from the mains. As a result, it can provide good flow and pressure at showers, baths and taps without a separate shower pump. However, the property must have suitable incoming water flow and pressure.

Where Can You Use a 250L Direct Unvented Cylinder?

The Gledhill ES 250L direct cylinder may suit larger family homes and properties with high hot water demand. For example, it may suit a home with several occupants, multiple bathrooms or several outlets that need hot water throughout the day.

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

However, every household uses hot water differently. The correct size depends on the number of occupants, bathrooms, showers, baths and taps. For this reason, ask a qualified installer to calculate the required capacity before you order.

Benefits of Mains-Pressure Hot Water

An unvented cylinder connects directly to the incoming mains water supply. Therefore, it removes the need for a traditional cold water storage tank in the loft and can provide stronger pressure than a basic gravity-fed system.

In addition, suitable mains flow can provide good performance at showers, baths and taps. However, the cylinder cannot improve a weak incoming supply. Your installer should test the property’s water flow and pressure before recommending an unvented system.

Why Choose a Gledhill Stainless ES Cylinder?

Gledhill is a well-known UK hot water cylinder manufacturer. Its Stainless ES range combines practical performance, strong materials and competitive value.

First, the Duplex stainless steel body provides strong protection against corrosion. Next, the 40mm insulation helps retain heat. Finally, the unvented design can provide strong hot water pressure when the property has a suitable mains supply.

The cylinder also includes key unvented controls and two immersion heaters. As a result, your installer can obtain the main cylinder and several important components in one package.
