Gledhill Stainless Platinum 150L Direct Unvented Cylinder – PLTDR150

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

The Gledhill Stainless Platinum 150L Direct Unvented Cylinder provides stored mains-pressure hot water for modern homes with moderate hot water demand. It has a nominal size of 150 litres and an actual capacity of approximately 139 litres.

Two 3kW Incoloy immersion heaters heat the stored water. Therefore, the PLTDR150 suits homes that use electricity for hot water rather than a boiler-fed heating coil.

The cylinder can use mains electricity or a suitable supply from photovoltaic solar panels. In addition, compatible off-peak electricity tariffs may help households heat water when energy prices are lower.

Gledhill makes the cylinder from high-specification Duplex stainless steel. Meanwhile, high-density HCFC-free Envirofoam insulation helps reduce heat loss and keep the stored water hot.

The internal expansion design removes the need for a separate external expansion vessel. As a result, the system takes up less space, looks neater and provides easier access for future maintenance.

• 1 x Gledhill Stainless Platinum unvented cylinder
• 2 x 3kW Incoloy immersion heaters
• 1 x lift-up temperature and pressure relief valve
• 1 x tundish

The cylinder uses an internal expansion system, so it does not need a separate external expansion vessel. However, your installer may need additional valves, discharge pipework and fittings to complete the installation.

Where Can You Use This 150L Direct Cylinder?

The Gledhill Stainless Platinum PLTDR150 may suit flats, apartments and family homes with moderate hot water demand. For example, it may suit a property with several occupants and a typical mix of showers, baths and taps.

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 homes with electric heating, no gas supply or a suitable photovoltaic system.

However, every home uses hot water differently. The correct size depends on the number of occupants, bathrooms and outlets. For this reason, ask a qualified installer to calculate the required capacity before ordering.

Benefits of Internal Expansion

Many unvented cylinders need a separate external expansion vessel. In contrast, the Gledhill Stainless Platinum manages expansion within the cylinder system.

Consequently, the installer has fewer external components to position around the cylinder. This design can save cupboard space, create a neater installation and provide easier access for maintenance.

Benefits of Mains-Pressure Hot Water

The cylinder connects directly to the incoming mains water supply. Therefore, it does not need a traditional cold water storage tank in the loft.

With suitable incoming flow and pressure, the PLTDR150 can provide strong hot water performance at showers, baths and taps. However, the cylinder cannot improve a weak mains supply. Your installer should test the available water flow and pressure first.

Why Choose a Gledhill Stainless Platinum Cylinder?

The Stainless Platinum range combines strong materials, internal expansion and practical electric water heating. As a result, it provides a neat solution for properties that need a direct unvented cylinder.

First, the Duplex stainless steel body helps resist corrosion. Next, the Envirofoam insulation helps retain heat. Finally, the internal expansion system reduces the number of external components needed around the cylinder.

In addition, two immersion heaters allow the cylinder to heat water without a boiler. This makes the PLTDR150 a practical choice for suitable all-electric homes.
