Unvented Cylinder Installation and Servicing

GCL Hopkins offers expert unvented hot water cylinder installation and servicing for homes and businesses in Leicester, Loughborough, and surrounding areas. Whether you are upgrading from a gravity-fed system or need routine maintenance, our certified engineers deliver professional solutions you can trust.

An unvented cylinder provides high-pressure hot water directly from your mains supply, ideal for modern homes that need efficient performance without bulky tanks.

What Is an Unvented Cylinder?

An unvented cylinder is a pressurised hot water storage system that connects directly to your mains. It delivers strong water flow to multiple outlets simultaneously without requiring a cold-water storage tank.

Key Benefits:

High water pressure for better showers and faster fills

Space-saving design with no attic tank required

Suitable for multi-bathroom properties

Energy-efficient performance

Compatible with renewable systems (solar thermal)

Installation Services

Every installation begins with a site survey to assess your water supply and home layout. Our engineers then design and fit the right system for your needs, handling:

Safe disconnection of old systems

Installation of cylinder, pipework, and fittings

Pressure and temperature regulation controls

Expansion vessel and safety valve setup

Full testing and certification

We provide clear, upfront pricing and complete documentation for compliance and peace of mind.

Servicing and Maintenance

Routine servicing is essential to keep your unvented cylinder performing safely and efficiently. A typical service includes:

Visual inspection for leaks or corrosion

Pressure relief valve checks
