Unvented hot water

If you are tired of weak water pressure in your shower or waiting ages for the hot water to reach your taps, an unvented hot water cylinder could be the perfect solution. Julian Paul Plumbing & Heating specialises in the installation, servicing, and repair of unvented hot water systems for homes across North London, delivering mains-pressure hot water to every outlet in your property.

Unlike traditional vented (gravity-fed) systems that rely on a cold water tank in the loft, unvented cylinders are connected directly to the mains water supply. This means they deliver hot water at mains pressure, giving you a powerful, consistent flow from every tap and shower in your home. This is particularly beneficial for properties with multiple bathrooms, where maintaining good water pressure is essential.

Our engineers are fully G3 qualified, which is the specific certification required by Building Regulations for working on unvented hot water systems. This ensures that your installation is carried out safely and in full compliance with all relevant regulations. We install leading brands including Megaflo, Heatrae Sadia, and Gledhill, and we will recommend the right cylinder size based on your household's hot water demand.

We also provide annual servicing for unvented cylinders, which is essential to maintain safety and efficiency. During a service, we check the temperature and pressure relief valves, the expansion vessel, and all safety controls to ensure everything is functioning correctly. Regular servicing not only keeps your system safe but also extends its lifespan and ensures you continue to enjoy reliable, high-pressure hot water for years to come.
