Unvented Water Cylinders – FAQs
Q: What is an unvented water cylinder?
A: An unvented water cylinder is a type of hot water storage system that works under pressure. Unlike vented systems, it doesn't require a cold water tank in the loft. Instead, it connects directly to the mains water supply, delivering high water pressure for better flow and performance.
Q: What are the benefits of an unvented water cylinder?
A: The main benefits include high water pressure throughout the property, no need for a cold water storage tank, and more efficient energy use. It also saves space in your loft or attic, which is a major advantage in modern homes.
Q: How does an unvented water cylinder work?
A: Unvented water cylinders work by heating water and storing it under pressure. The water is heated using an immersion heater or a central heating system, and when you turn on a tap, the pressurised water flows out at high speed, providing a powerful shower or bath.
Q: Do I need to install an unvented cylinder in my home?
A: If you’re looking for higher water pressure or have a larger home, an unvented water cylinder could be a great solution. However, it may not be necessary if your home already has adequate water pressure or if you have a smaller property.
Q: Can I install an unvented water cylinder myself?
A: No, the installation of an unvented water cylinder must be carried out by a qualified and certified installer. In the UK, this work should be done by someone with a G3 unvented cylinder qualification to ensure safety and compliance with regulations.
Q: How long does an unvented water cylinder last?
A: Unvented water cylinders are designed to last for up to 20 years or more if properly maintained. Regular servicing can help extend the life of your cylinder and ensure it’s operating efficiently.
Q: Are unvented cylinders energy-efficient?
A: Yes, unvented cylinders are generally very energy-efficient, as they retain heat for long periods. This means you can get hot water on demand without constantly reheating it, which can save you money on energy bills.
Q: Do I need to service my unvented water cylinder?
A: Yes, regular servicing is recommended for unvented water cylinders to ensure that they’re working efficiently and safely. Annual inspections by a qualified engineer can help identify any issues early and maintain optimal performance.
