Unvented Hot Water Cylinder Installation in Heswall, Wirral

The biggest frustration we hear from families in Heswall is that they can't use two taps at once. If someone starts the washing machine while you're in the shower, the temperature or pressure usually takes a dive. With an unvented cylinder—often referred to by the popular brand name Megaflo—those days are over. Because these systems are 'mains-fed', they provide what we call balanced pressure. This means your hot and cold water are delivered at the same high pressure, allowing you to run multiple bathrooms simultaneously with ease. It is the perfect solution for larger households or those planning a home extension. Plus, because the cylinders are heavily insulated, they keep your water hot for much longer, which is a nice win for your energy bills too.

Have you ever thought about what is actually sitting in that big plastic or galvanised tank in your loft? Over the years, gravity-fed tanks can collect dust and debris, which isn't ideal for your hot water supply. One of the best perks of an unvented hot water cylinder installation is that it completely removes the need for those bulky loft tanks. If you are considering a loft conversion in the future, or just want to clear out some clutter, this upgrade is a game-changer. By moving to a sealed system, you're not just improving pressure; you're creating a cleaner, more efficient, and more reliable way to heat your home's water. We handle the entire transition, from safely disposing of your old tanks to installing the sleek new cylinder in a more convenient spot like an airing cupboard or utility room.

Installing an unvented cylinder isn't a job for a general DIY-er or an uncertified plumber. Because these systems hold water under high pressure, they are governed by strict building regulations known as Part G. To install or service them legally and safely, an engineer must hold a specific G3 qualification. At Redorr Heating & Cooling Services Ltd, our engineers are fully G3 certified and Gas Safe registered (967977). We take safety incredibly seriously, ensuring every installation includes the correct expansion vessels, pressure relief valves, and a properly installed tundish—that little plastic funnel that acts as a visible safety indicator. We don't just fit the tank and leave; we commission the system to the highest standards and provide you with all the necessary paperwork for building control compliance.

Like any high-performance piece of kit, your unvented 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 service visit, we check the safety valves, recharge the expansion vessel, and ensure there are no signs of wear that could lead to a leak. If you've already got an unvented system and noticed your hot water isn't as punchy as it used to be, or if you've spotted water dripping from the discharge pipe, give us a call. We're local to the Wirral and can usually get someone out to Heswall quickly to diagnose the fault and get your pressure back to where it should be. We also provide landlord safety certificates and support for commercial properties across the North West.
