Unvented Hot Water Cylinder Installation in Lees, Oldham

Most of us grew up with a 'vented' system, which usually involves a large, heavy cold water storage tank sitting in the attic. Not only do these take up a lot of space, but they are also prone to freezing in the winter and can sometimes collect debris over the years. By switching to a modern unvented cylinder—often referred to by the popular brand name 'Megaflo'—you can completely remove those tanks from your loft. This is a total game-changer if you are planning a loft conversion or just want more storage space. Because the cylinder is a sealed unit, the water stays fresh and is delivered at the same pressure as your cold mains. It is a cleaner, more compact, and much more efficient way to keep your home in Lees supplied with hot water.

Installing an unvented hot water cylinder is not a job for a DIY enthusiast or an uncertified plumber. Because these systems operate under high pressure, they fall under 'Part G' of the Building Regulations. This means the person doing the work must be G3 qualified by law. Our team at Redorr Heating & Cooling Services Ltd are fully certified (Gas Safe 967977) and experienced in handling these complex installations safely. We take care of every technical detail, from setting up the expansion vessel to ensure the system can handle pressure changes, to installing the 'tundish'—that little plastic device that lets you see if a safety valve is discharging. We don't just fit it and leave; we commission the system properly and provide you with the necessary paperwork to show your home is compliant.

Whether you are renovating a terrace in the heart of Lees or building a new extension in the wider Oldham area, an unvented cylinder is often the best choice for energy efficiency. These cylinders are incredibly well-insulated, meaning they lose very little heat over 24 hours compared to older models. They can be 'indirectly' heated by your boiler or 'directly' via immersion heaters, making them compatible with almost any setup. Many homeowners we speak to in the North West are also looking at long-term savings; by pairing a high-efficiency cylinder with our other services, like radiator powerflushing or even an air source heat pump, you can significantly reduce your energy bills while enjoying much better performance.

Just like your boiler, an unvented hot water cylinder needs a little bit of TLC to keep it running safely. Because they contain several safety valves and an expansion vessel that needs to be checked, an annual service is highly recommended—and often required to keep your manufacturer's warranty valid. If you have noticed your water pressure dropping or if there is water constantly dripping from your overflow pipe, give us a call. We don't just do new installations; we are also experts at fault-finding and repairing existing unvented systems. We carry £10 million in public liability insurance, so you can have total peace of mind that your home is in safe hands while we work.
