Unvented Hot Water Cylinder Installation in New Mills, Derbyshire

Most homeowners we speak with are still using 'vented' systems, which usually involve a large, dusty cold water tank sitting in the loft. These rely on gravity to push water down to your taps, which is why your upstairs shower often feels weak. An unvented cylinder, like the popular Megaflo models, does away with the loft tank entirely. Because it's fed directly from the cold water main, you get 'balanced' pressure throughout the house. This means you can finally enjoy a 'power shower' performance without the need for those noisy, vibrating electric pumps that seem to wake the whole street up at 6 am.

While unvented cylinders are fantastic for performance, they are high-pressure systems that require specialist handling. It isn't just a recommendation—it's a legal requirement under Building Regulations that these are installed by someone with a G3 qualification. Our team at Redorr Heating & Cooling Services Ltd are fully certified and Gas Safe registered (967977), ensuring every safety component, from the expansion vessel to the tundish, is fitted perfectly. We take safety seriously, which is why we also carry £10 million in public liability insurance. When we work in your home, we treat it with the same care we’d treat our own, ensuring everything is Part G compliant and thoroughly tested before we head off.

Are you planning a loft conversion or adding an ensuite? If so, an unvented hot water cylinder is often the best move you can make. One of the biggest perks of these systems is the space you gain; by removing that bulky cold water tank from the loft, you suddenly have more room for a new bedroom or a quiet home office. Plus, because the hot water is delivered at mains pressure, you can run multiple bathrooms at the same time without the temperature plummeting the moment someone else turns on a kitchen tap. It’s the ideal setup for busy High Peak households where everyone seems to need the bathroom at once.

We often get asked if these modern cylinders are expensive to run. Actually, modern unvented cylinders are incredibly well-insulated, often keeping water hot for days with minimal heat loss. Whether you want an 'indirect' model that works with your existing boiler or a 'direct' version that uses immersion heaters, we can help you choose the right capacity for your family’s needs. We’ve been helping neighbours across New Mills, High Peak, and Derbyshire upgrade their systems to be more reliable and energy-efficient, often as part of a wider central heating upgrade or a brand-new bathroom refurbishment.
