Vented and Unvented Hot Water Cylinders

The correct type of cylinder depends on your property, existing plumbing system, water pressure, available space, and expected hot water demand.

Vented cylinders are usually supplied by a cold-water storage tank and are commonly found in older properties. They provide a dependable solution where the existing gravity-fed system is in good condition.

Unvented cylinders are connected directly to the mains water supply and can provide stronger water pressure at showers and taps. They are often suitable for modern homes, larger properties, and buildings with multiple bathrooms or higher hot water demand.

Our engineers will explain the differences clearly and help you choose a system that suits your property and budget.

Signs Your Hot Water Cylinder May Need Attention

Common signs of a cylinder problem include:

• Running out of hot water too quickly
• Water taking longer than normal to heat
• Poor hot water pressure
• Leaks around the cylinder or connected pipework
• Unusual banging, hissing, or rumbling noises
• Water that is too hot or not hot enough
• A faulty immersion heater
• Water discharging from a safety or overflow pipe
• Visible corrosion or damage around the cylinder

Addressing these issues early can help prevent further damage, reduce energy waste, and avoid a complete loss of hot water.

Correctly Sized for Your Property

A hot water cylinder must be large enough to meet the daily demands of the property without wasting energy by storing more water than necessary.

Before installation, we consider the number of occupants, bathrooms, showers, appliances, peak usage times, available water pressure, and existing heating system. This allows us to recommend a cylinder with the appropriate capacity and performance.

For commercial and multi-occupancy properties, we can design systems capable of supporting higher and more consistent hot water demand.

Safe Installation and Reliable Performance

Hot water cylinders contain pressurised water, high temperatures, and essential safety controls, so correct installation and maintenance are vital.

Our engineers complete all relevant pipework, valves, discharge arrangements, controls, and system connections carefully. Once installed, the cylinder is tested to confirm that it operates safely, efficiently, and as intended.
