What We Cover
What Is an Unvented Cylinder?
An unvented cylinder is a sealed hot water storage system connected directly to the mains water supply, delivering strong, even water pressure to every tap and shower in your home without needing a cold water tank in the loft. Unvented hot water systems are now the standard choice for modern UK homes because they’re compact, efficient, and provide consistent mains-pressure performance throughout the property.
How Unvented Cylinders Differ from Vented Systems
Traditional vented systems rely on gravity and a loft-mounted cold water tank, which often results in weak, inconsistent pressure especially on upper floors. An unvented cylinder, by contrast, draws water straight from the mains, so pressure stays strong no matter how many outlets are in use at once.
Mains Pressure Hot Water System Explained
Mains pressure hot water systems use the incoming pressure from your water supply rather than gravity, which is why unvented cylinders can deliver powerful showers and fast-filling baths even in properties with no loft space at all.

Key Components
Key Components of an Unvented Cylinder System in Glasgow
Every unvented hot water cylinder relies on a set of safety and control components working together. Here’s what’s fitted as standard on every installation:
Expansion Vessel
Absorbs the increase in water volume as it heats. This prevents excess pressure building up inside the sealed system. It's a key part of keeping your cylinder safe long-term.
Temperature and Pressure Relief Valve (TPRV)
A critical safety device fitted to every unvented cylinder. It automatically releases water if temperature or pressure exceeds safe limits. This protects the system from dangerous over-pressurisation.
Pressure Reducing Valve (PRV)
Regulates incoming mains pressure to a safe, consistent level. This ensures water reaches the cylinder at the correct pressure. It also protects other components from excess strain.
Tundish
A visible air-gap fitting installed in the discharge pipe. It allows engineers to monitor for valve leaks or discharges. Any drips here signal a fault that needs attention.
Combination Valve
Combines several safety functions into a single compact unit. This includes pressure relief and non-return protection. It simplifies the system while maintaining full compliance.
Immersion Heater & Dual Thermostat
Provides backup or primary heating for the stored water. A dual thermostat controls temperature and prevents overheating. This adds an extra layer of safety and reliability.
Drain Cock
Allows the cylinder to be safely and fully drained down. This is essential for servicing, repair, or replacement work. It gives engineers safe, controlled access to the system.
