Unvented Hot Water Cylinder Installation in Leigh, Wigan

Most homeowners we speak to in the Wigan area are used to the 'vented' way of doing things—a copper cylinder in the airing cupboard and a big plastic tank in the loft. While it has worked for decades, it relies on gravity to get water to your taps. If your shower is on the same floor as that tank, the pressure is never going to be great. By switching to an unvented system, often referred to by the popular brand name Megaflo, you can actually get rid of those dusty tanks in the roof altogether.Think about what you could do with that extra space! Many of our customers in Leigh choose an unvented installation specifically because they are planning a loft conversion and need to clear the area. Beyond just saving space, these cylinders are incredibly well-insulated. They act like a massive Thermos flask, keeping your water hot for much longer and helping you trim down those monthly energy bills.

Are you planning a new ensuite or a second bathroom? If so, your current boiler and tank might struggle to keep up. An unvented cylinder is the gold standard for modern living because it provides what we call 'balanced pressure'. This means the hot and cold water come out at the same force, making it much easier to mix the perfect temperature and keep it that way.Power shower performance: No need for noisy, expensive electric pumps to get a decent flow.Multiple outlets: You can run the bath, the dishwasher, and the shower simultaneously without a drop in performance.Reliability: Because they are sealed systems, they are less prone to the contamination issues sometimes found in open loft tanks.Our team of Wigan heating experts will assess your home’s mains pressure first to ensure an unvented system is the right fit for you. We don't believe in 'one size fits all'—we want to make sure you get the best possible result for your specific property.

Because unvented cylinders store water under pressure, they require specialist safety features like expansion vessels and a 'tundish' (the little plastic funnel that lets you see if the safety valves are working). Because of this, it is actually a legal requirement that they are installed by someone with a G3 Building Regulations qualification. You shouldn't trust this job to just any handyman.At Redorr Heating & Cooling Services Ltd, our engineers are fully G3 qualified and Gas Safe registered (967977). We handle the entire process, from the initial design and sizing of the cylinder to the final commissioning and notification to local building control. We also carry £10 million in public liability insurance, so you can put your feet up with a cuppa knowing your home is in the safest possible hands. We take pride in our tidy work, ensuring all pipework is neat and the site is left spotless when we’re done.

Just like your car or your boiler, an unvented hot water cylinder needs a little bit of love to keep it running at its best. Imagine if a safety valve became blocked with limescale; it could lead to much bigger issues down the line. We recommend a quick annual service to check the internal pressures, test the safety relief valves, and ensure the expansion vessel is charged correctly.If you already have a cylinder and have noticed it is making strange noises, or if you’ve spotted water dripping from the discharge pipe outside, give us a call. We provide expert cylinder repairs and water heater servicing across Leigh and Wigan. Catching a small issue early is always much cheaper than dealing with a major breakdown in the middle of a busy week.
