FAQs
What’s the difference between vented and unvented cylinders?
Vented cylinders are gravity-fed and require a cold water tank, while unvented cylinders are mains-fed and offer better pressure. We’ll help you choose the right type for your home.
How long does installation take?
Most installations are completed within one day, depending on access and system complexity.
Can I replace my old copper cylinder with a modern unvented one?
Yes, we can upgrade your system and bring it up to current safety and performance standards.
Is planning permission or a building notice required?
Unvented cylinders must be installed by a qualified engineer and may require building control notification—we handle all the compliance for you.
