Unvented Hot Water Cylinder Installation in Prescot, Knowsley

Most homeowners we speak to in Prescot tell us the same story: they've spent a fortune on a beautiful new bathroom, only to find the water pressure is pathetic. The reason is usually a 'vented' cylinder. These systems rely on gravity to push water down from the attic. If your shower isn't much higher than your tank, you're never going to get a decent flow. An unvented cylinder, like the famous Megaflo brand, changes the game entirely. Because it's connected directly to your cold water main, the hot water comes out at the same pressure as your cold water. It's a simple change that makes a massive difference to your daily routine, especially in larger homes with multiple bathrooms where everyone is trying to get ready at the same time.

Have you ever thought about what's actually inside those old tanks in your loft? They often collect dust, debris, and sometimes even the odd unlucky bird or rodent. Switching to an unvented system means we can remove those tanks entirely. If you're planning a loft conversion in Knowsley, this is a total lifesaver, as it frees up valuable floor space for an extra bedroom or office. Beyond the space savings, modern cylinders are incredibly well-insulated. Think of them like a giant, high-tech Thermos flask; they can keep your water piping hot for days, reducing the amount of work your boiler has to do and helping to keep those energy bills under control.

Installing an unvented cylinder isn't a job for a general handyman. Because these systems hold water under high pressure, they have to be installed with specific safety features like expansion vessels and a tundish—that little visible plastic drain that lets you see if the system is discharging excess pressure. It’s actually a legal requirement under G3 Building Regulations that the person installing your cylinder is specifically qualified to do so. Our team at Redorr Heating & Cooling Services Ltd is fully G3 certified and Gas Safe registered (967977). We don't just fit the tank; we carefully calculate the right size for your family's needs, ensure the pipework is balanced, and commission the system to make sure it's running perfectly and safely from day one.

Like any major appliance, a hot water cylinder needs a bit of love to keep it running smoothly. We recommend an annual service to check the safety valves and the internal pressure. If you've noticed your water isn't as hot as it used to be, or if you spot water dripping from the discharge pipe, it’s worth giving us a call. We're based just down the road in Warrington and cover the whole of Prescot and Knowsley. We pride ourselves on being honest and transparent—we'll always explain what needs doing and give you a fair price before we start.
