Expert Unvented Hot Water Cylinder
Installation in Warrington & Merseyside
G3 qualified specialists providing powerful, mains-pressure hot water solutions.

Upgrade to powerful mains pressure hot waterMost of us grew up with a 'vented' system—that big cold water tank sitting in the loft, gathering dust and occasionally causing a headache. These systems rely on gravity to push water down to your taps, which is why the pressure is often so poor on the top floor. An unvented hot water cylinder, like the popular Megaflo models we often install, does away with those attic tanks entirely.Because these cylinders are connected directly to your cold water mains, the hot water comes out at the same high pressure as your cold water. This 'balanced pressure' is exactly what modern mixer showers and luxury taps need to perform at their best. Imagine being able to run two showers and a bath at the same time without anyone losing pressure. It is not just a luxury; for busy families in Cheshire and Merseyside, it is a total lifestyle upgrade.Consistent High Pressure: Enjoy powerful showers without the need for expensive, noisy electric pumps.Multiple Tap Use: Use hot water in the kitchen and the bathroom simultaneously with no drop in performance.Better Hygiene: You are getting fresh water straight from the mains rather than water that has been sitting in an open tank in the loft.

Reclaim your loft space and improve efficiencyAre you planning a loft conversion or just wish you had more storage space for the Christmas decorations? One of the biggest 'hidden' benefits of an unvented hot water cylinder is the space it saves. Since the system doesn't require a header tank in the roof, we can remove those bulky plastic or metal containers, freeing up valuable square footage. This makes unvented cylinders the perfect partner for homeowners looking to extend upwards.Beyond the space-saving perks, these modern cylinders are incredibly well-insulated. Redorr Heating & Cooling Services Ltd only installs high-quality units designed to keep your water hotter for much longer. This means your boiler doesn't have to work as hard to maintain temperatures, which can lead to lower energy bills over time. Whether we are installing a brand-new unit or carrying out domestic water heating upgrades, our focus is always on making your home more efficient and comfortable.

Safe and legal G3 qualified engineersWhen it comes to unvented hot water cylinders, you cannot just hire any odd-job man. Because these systems are under high pressure, they must be installed by someone with a specific G3 qualification. This is a legal requirement under Part G of the Building Regulations. At Redorr Heating & Cooling Services Ltd, our engineers are fully G3 qualified and Gas Safe registered (967977), ensuring your installation is safe, compliant, and fully insured with our £10m public liability cover.During the installation, we pay close attention to vital safety components like the expansion vessel and the tundish. The tundish is that little plastic funnel you might see near the cylinder—it is a safety device that allows you to see if the system is over-pressurising. We take the time to explain how your new system works and what to look out for, giving you total peace of mind that your home and family are in safe hands. We handle everything from the initial pipework to the final commissioning and building reg notification.

Reliable unvented cylinder maintenance and servicingJust like your car or your boiler, an unvented hot water cylinder needs a little bit of love to keep it running at its best. Most manufacturers require an annual service to keep your warranty valid. During a routine check, we’ll inspect the safety valves, check the internal pressure, and ensure the expansion vessel is charged correctly. If you've noticed your water pressure isn't what it used to be, or if there is water dripping from the discharge pipe, it is time to give us a call.We don't just do new installations; we are also experts in hot water cylinder servicing and repairs across Warrington and the surrounding 25-mile area. If your current system is acting up, we can diagnose the fault and get your hot water back to full strength quickly. Regular maintenance prevents small issues from turning into expensive emergencies, ensuring your morning shower stays powerful for years to come.
