Gledhill Stainless ES Cylinders: Quality Hot Water at a Competitive Price
Gledhill Stainless ES Cylinders Buying Guide: A reliable hot water cylinder plays an important role in any home. It must provide enough hot water, maintain strong pressure and deliver dependable performance every day.
The Gledhill Stainless ES range offers an excellent balance of quality, durability and value. Available from SNH Tradecentre, these unvented cylinders provide mains-pressure hot water for showers, baths and taps throughout the property.
What Is a Gledhill Stainless ES Cylinder?
The Gledhill Stainless ES is a value-engineered unvented hot water cylinder. It benefits from Gledhill’s proven manufacturing experience while remaining competitively priced.
Gledhill manufactures the internal cylinder from corrosion-resistant Duplex stainless steel. The range also carries independent NSF WRC and WRAS approvals. Gledhill Stainless ES product information.
Because it is an unvented cylinder, it connects to the incoming mains water supply. Therefore, it can provide powerful hot water without requiring a traditional cold-water storage tank in the loft.
Actual pressure and flow will depend on the incoming mains supply, pipework and installation design.

Direct and Indirect Gledhill ES Cylinders
The range includes both direct and indirect models.
Gledhill ES Direct Cylinders
A direct cylinder heats the stored water using electric immersion heaters. It does not rely on a gas or oil boiler.
Direct models are a suitable choice for:
- Flats and apartments without a boiler
- All-electric homes
- Properties using off-peak electricity tariffs
- Replacing an existing direct unvented cylinder
- Buildings where a gas supply is unavailable
The immersion heaters can provide a full electric hot water solution. However, the installer should correctly size the cylinder for the household and its expected hot water use.
Gledhill ES Indirect Cylinders
An indirect cylinder uses a boiler and internal heating coil to heat the water. It also includes an immersion heater for backup or emergency use.
Indirect models are ideal for:
- Homes with a system or regular boiler
- Replacing an older indirect cylinder
- Properties requiring faster hot water recovery
- Family homes with regular hot water demand
- Installations requiring mains-pressure showers and taps
The correct choice will depend on the property’s heating system. Therefore, always confirm whether a direct or indirect cylinder is required before ordering.

As a general guide, smaller cylinders may suit flats and one-bedroom homes. Meanwhile, larger households with baths, powerful showers or several bathrooms will usually need more stored hot water.
However, cylinder sizing should consider:
- Number of occupants
- Number of bathrooms
- Baths or showers used
- Shower flow rates
- Available mains water pressure
- Expected simultaneous demand
- Space available for installation
- Heat source and recovery time
A qualified installer should calculate the correct capacity rather than simply replacing the old cylinder with the same size.
