Unvented Cylinders
An unvented hot water cylinder provides mains-pressure hot water throughout your home, delivering powerful showers and faster-filling baths without the need for cold water tanks in your loft. At Geco Plumbing, we specialise in the installation and servicing of unvented cylinders, offering homeowners a reliable solution for high-performance hot water systems that work efficiently with modern boilers and renewable heating technologies.
Unlike traditional vented cylinders that rely on gravity-fed cold water from a loft tank, unvented cylinders connect directly to your mains water supply. This delivers hot water at mains pressure to all outlets simultaneously, meaning you can run multiple showers or fill a bath quickly without any loss of pressure. For households with modern bathrooms featuring powerful showers or multiple bathrooms in use at the same time, an unvented cylinder is often the best solution. They’re also increasingly popular in new builds and renovations where loft space is limited or where installing cold water tanks isn’t practical.

Benefits Of Unvented Hot Water Systems
The most immediate benefit of an unvented cylinder is the significantly improved water pressure throughout your home. Showers deliver invigorating performance, baths fill quickly and taps run at excellent pressure. If you’ve ever experienced the frustration of weak showers or long waits for baths to fill, an unvented system transforms your daily routine. The improved pressure also means you can fit power showers and multi-head shower systems that simply wouldn’t work properly with traditional vented systems.
Beyond performance, unvented cylinders offer practical advantages for your home’s design and energy efficiency. With no need for cold water tanks in your loft, you free up valuable storage space and eliminate the risk of frozen or leaking header tanks. Unvented systems are also more energy-efficient because they don’t lose heat through pipework running to and from loft tanks. Modern unvented cylinders feature excellent insulation that minimises heat loss, and they work seamlessly with condensing boilers, heat pumps and solar thermal systems, making them ideal for eco-conscious homeowners looking to reduce energy consumption.
