Vented Cylinders in Yeovil & Sherborne
Our Gas Safe registered engineers specialize in the installation and maintenance of vented hot water cylinders across Yeovil, Sherborne and surrounding areas. These traditional water storage systems are perfect for properties with existing cold water tanks and offer reliable hot water supply.
What is a Vented Hot Water Cylinder?
A vented hot water cylinder is a traditional system that works with a cold water storage tank, typically located in your loft. The cold water flows down from the tank into the cylinder where it's heated either by your boiler or an immersion heater.
This system uses gravity to create water pressure, which is why the storage tank needs to be positioned above the cylinder. The system includes a vent pipe that connects back to the cold water tank, which acts as a safety feature to release any excess pressure.
Benefits of Vented Hot Water Cylinders

Key Components of an Unvented System
Expansion vessel to handle increased water volume when heated

Unvented Cylinders in Yeovil & Sherborne
Our experienced gas engineers provide professional installation and maintenance of unvented cylinders across Yeovil, Sherborne and surrounding areas. We offer comprehensive boiler services and hot water solutions to meet all your needs.
What is an Unvented Hot Water Cylinder?
An unvented hot water cylinder is a modern system that connects directly to your mains cold water supply, eliminating the need for a cold water storage tank in the loft. The cylinder is pressurized and uses the mains pressure to deliver hot water to your taps and showers, typically providing better pressure than a vented system.
Instead of a vent pipe, these systems use built-in safety devices including expansion vessels, temperature relief valves, and pressure relief valves. This makes them more complex than vented systems, which is why they must be installed and maintained by qualified professionals.
Choosing Between Vented and Unvented Cylinders
The choice between vented and unvented cylinders depends on several factors including your property type, existing setup, and hot water requirements. Here's a quick comparison to help you decide:
Vented Systems Best For:
Properties with existing cold water tanks
Homes with lower water pressure requirements
Budget-conscious installations
Simpler maintenance requirements
Traditional heating systems
Unvented Systems Best For:
Properties needing high water pressure
Homes with multiple bathrooms
Limited loft space
Modern heating systems
Properties with good mains pressure

Chris altered the boiler pipe work so that the Magnaclean filter was not only accessible but is now protecting the systems it was meant to protect.

Will definitely use him again and recommend him to all.
