Bathroom and central heating repair and installation in Nottinghamshire At K1 Plumbing & Gas Services we treat every emergency plumbing and boiler enquiry with the utmost urgency. Our Gas Safe registered engineers are available 24 hours a day to help with your boiler and central heating problems. With 25 years of experience, we can deal with any emergency situation. Alongside our emergency service, we also design, install and maintain all gas boilers and central heating systems. As experienced plumbers, we can also undertake any bathroom installation including the tiling and ancillary building work. If you are hearing kettling, banging or popping noises in the central heating boiler, this is usually caused by limescale and corrosion debris. We can power flush your entire system to remove rust and sludge. This cleans the heat transfer surfaces, restores efficiency and eliminates the boiler noises. For older systems we can perform a boiler swap, replacing your old gas boiler with one of the latest models to give you an energy efficient central heating system
