Unvented Hot Water Cylinder Installation in Wallasey, Wirral

Most traditional homes in Wallasey have a 'vented' system. You will know if you have one because there is usually a large, dusty cold water tank sitting in your loft. These systems rely on gravity to push water down to your taps, which is why the pressure is often so poor. An unvented cylinder, like the popular Megaflo models, connects directly to your cold water mains. This means your hot water comes out at the same pressure as your cold water. Not only does this give you a 'power shower' experience without needing an expensive pump, but it also frees up valuable space in your loft—perfect if you are planning a loft conversion or just want more storage room.

Installing an unvented hot water cylinder is not a DIY job or something for an unqualified handyman. Because these systems hold water under high pressure, they must be installed correctly to stay safe. In the UK, it is a legal requirement under Part G of the Building Regulations that only a G3 qualified engineer carries out this work. Our team at Redorr Heating & Cooling Services Ltd are fully G3 certified and Gas Safe registered (967977). We take safety seriously, ensuring every installation includes the necessary expansion vessels and a tundish—that little plastic device that lets you see if the system is ever over-pressurising. With our £10 million public liability insurance, you can rest easy knowing your home is in safe, professional hands.

What are the real-world benefits of making the switch? Beyond just a better shower, unvented cylinders are incredibly well-insulated. Think of them like a giant, high-tech Thermos flask; they keep your water hot for ages, which can help reduce your energy bills.

• Multiple Bathrooms: You can run two showers at once without either person losing pressure.
• Balanced Pressure: No more sudden bursts of freezing or scalding water when a toilet is flushed.
• Quieter Home: You can say goodbye to those noisy, vibrating shower pumps in the airing cupboard.
• Flexible Location: Because they don't rely on gravity, we can often install the cylinder in a basement, garage, or utility room rather than just the airing cupboard.

If you already have an unvented system, you probably know how great they are—until they start playing up. Maybe you've noticed water dripping from a pipe outside, or perhaps your pressure has slowly started to drop. These systems need an annual service to check the safety valves and re-pressurise the internal air gap or expansion vessel. We provide thorough maintenance checks across Wallasey and the wider Wirral area to keep your system running efficiently. If you are a landlord, we can also take care of your annual safety certifications alongside your boiler service, making sure your property remains fully compliant with current regulations.
