Types of Hot Water Cylinders We Service

Unvented Hot Water Cylinders

Unvented cylinders connect directly to your mains supply, delivering powerful high-pressure hot water on demand, ideal for homes with multiple bathrooms, modern showers, or those upgrading from gravity-fed tanks. There’s no need for a cold water tank in your loft, making them space-saving and suitable for renovation projects. We install, repair, and maintain unvented cylinders (including safety valves, expansion vessels, thermostats) to keep your system efficient and protect your family.

Vented Hot Water Cylinders

Traditional, vented cylinders are gravity-fed from a loft cold water tank. These are common in older homes and offer reliable, low-cost hot water, but with lower pressure. Urbangph supplies, repairs, and upgrades vented copper tanks, fitting modern foam jackets, updating controls, and ensuring safe operation. We also install combination tanks for flats and smaller spaces

Direct & Indirect Cylinders

We fit, repair, and service both direct (immersion heater only) and indirect (boiler, solar, or heat pump coil plus back-up elements) cylinders, tailoring your system for maximum efficiency and year-round hot water reliability.
