How to Choose Between Vented and Unvented Cylinders: A Buyer's Guide
Vented Cylinders
What They Are: A vented cylinder is a traditional and commonly used hot water storage system. It's called 'vented' because it's connected to a vent pipe, allowing gases to escape, and maintaining pressure within the system.
How it Works: The vented cylinder is fed by a cold-water storage tank, usually located in the loft. The stored water is then heated by a boiler or immersion heater and distributed throughout the home.
Pros:
Affordability: Generally, more affordable to install and maintain.
Lower Maintenance: Simpler system that's straightforward to repair, reducing long-term costs.
Reliability: Less prone to pressure-related issues, providing steady performance.
Suitable for Low Water Pressure: Can work well in properties with low water pressure.
Cons:
Space Consumption: Requires an additional water tank, usually in the loft, taking up more space.
Lower Water Pressure: Often delivers lower water pressure in showers and taps.
Potential for Running Out: If the tank is empty, the heated water supply may run out temporarily.
Less Energy Efficient: Can be less energy-efficient than unvented systems.
Unvented Cylinders
What They Are: An unvented cylinder is a more modern type of hot water storage system that provides a pressurised supply of hot water directly from the mains. Unlike vented cylinders, there's no need for a separate cold-water tank.
How it Works: The unvented cylinder is connected directly to the mains water supply and utilises a pressure control valve to regulate pressure. The water is heated either by an external heat source like a boiler or an internal immersion heater.
Pros:
High Water Pressure: Delivers high water pressure for a better shower and bath experience.
Space-Saving: No need for a separate water tank, freeing up loft space.
Consistent Water Temperature: Offers more consistent and controlled water temperature.
Energy Efficiency: Often more energy-efficient, potentially lowering utility bills.
Better Aesthetics: Cleaner installation without the need for visible tanks or additional pipework.
Cons:
Higher Costs: Generally, more expensive to install and maintain.
Regular Professional Maintenance Required: Needs to be serviced regularly by a certified engineer, adding to costs.
Pressure Sensitivity: Can be affected by changes in main water pressure.
Potential for Complex Issues: More complex system that can be more difficult and costly to repair.
How to Make Your Choice
When deciding between vented and unvented cylinders, consider the following:
Budget: Vented systems are typically more budget-friendly, both in installation and maintenance.
Space: If loft space is a concern, an unvented system might be a better fit.
Water Pressure: For homes with low water pressure, a vented system could be more suitable, while those looking for higher pressure might prefer an unvented cylinder.
Maintenance Requirements: Unvented cylinders require regular servicing by a certified professional, while vented cylinders tend to have lower maintenance needs.
