What Is an Unvented Cylinder?
An unvented hot water cylinder is a sealed system that delivers mains-pressure hot water without needing a cold-water storage tank. This means:
✅ Stronger water pressure – Ideal for power showers & multiple bathrooms
✅ More space in your home – No bulky water tanks in the loft
✅ Improved energy efficiency – Better heat retention & lower energy bills
✅ Reduced risk of contamination – No stagnant water in a storage tank
Popular brands we install include Megaflo, Gledhill, Joule, and Heatrae Sadia, ensuring you get a high-quality, long-lasting system.
