G3 Unvented Cylinder Installation in Keynsham , Bath and North East Somerset

Every home has different plumbing requirements, which is why we take a tailored approach to every installation. First, we test your incoming water pressure and flow rate to ensure your mains water supply can support an unvented system.Next, we safely decommission and remove your old vented cylinder and loft tanks. Our team will then carefully position and install your new cylinder, fitting a reliable stopcock and appropriate isolation valve controls for future maintenance.Finally, we rigorously test the system to ensure safe operation. We check the expansion vessel, temperature relief valves, and discharge pipework, leaving you with a highly efficient and fully compliant hot water solution.

The most noticeable benefit of an unvented system is the dramatic hot water pressure improvements. Because the water is supplied at mains pressure, you can enjoy powerful showers without needing to install noisy shower pumps. It provides the perfect flow for modern thermostatic mixer showers and large bath taps.Additionally, removing the cold water storage tank frees up valuable loft space, making it ideal for loft conversions or general storage. Unvented cylinders are also highly insulated, meaning they retain heat far better than older copper cylinders, helping to reduce your energy bills.With no header tank, the system is also entirely sealed. This eliminates the risk of contaminated water or frozen pipes in the loft during cold Somerset winters.

Unvented cylinders store water under significant pressure, meaning they must be installed with strict safety measures in place. It is a legal requirement that any installation or maintenance is carried out in accordance with Building Regulations G3.At BC Plumbing, we hold full G3 Certification alongside our Plumbing Part 1 and 2 qualifications. This guarantees that your installation is completely safe, legally compliant, and officially registered with the local authority.We also ensure that all fitted components, from the pressure reducing valves to your new taps, are strictly WRAS approved. This protects the integrity of your water supply and provides total peace of mind for you and your family.

Homeowners in Keynsham, Bath, and the surrounding Somerset areas often deal with hard water. Over time, limescale can build up inside your heating systems, reducing efficiency and potentially damaging the heating coil or safety valves of an unvented cylinder.To protect your investment, BC Plumbing can install inline scale reducers or water softeners alongside your new cylinder. This acts as a vital line of defence, ensuring your system maintains maximum efficiency and preventing premature breakdowns.If you already have a pressurised system that is suffering from limescale damage, we offer comprehensive maintenance and repair services to restore your hot water supply quickly and safely.
