Hot water cylinders are the heart of many heating systems — particularly in older North West properties that have never had a combi boiler fitted, and in larger homes where a combi wouldn't meet demand. EP 24/7 installs, replaces, and repairs both vented and unvented cylinders across the region. Contact us for a free quote.

Vented cylinders

The traditional copper cylinder fed by a cold-water tank in the loft. Common in older properties throughout Merseyside and the wider North West. We repair, replace, and where necessary upgrade these systems.

Unvented cylinders

Unvented cylinders connect directly to the mains water supply and deliver hot water at mains pressure — ideal for properties where shower pressure is poor. They must be installed and maintained by a suitably qualified engineer and require annual servicing.

When to replace a cylinder

Signs that a cylinder may need replacing include persistent lukewarm water, visible corrosion or rust-coloured water, an ageing cylinder that requires constant attention, or a switch from a gravity-fed to a mains-pressure system.

Frequently Asked Questions

What's the difference between vented and unvented?
Vented cylinders work at low pressure fed by a tank in the loft. Unvented cylinders connect directly to the mains and deliver hot water at mains pressure — better for showers and larger properties.
How often does an unvented cylinder need servicing?
Annually. The pressure relief valve and expansion vessel need to be checked every year to ensure the system is operating safely.
How much does a cylinder replacement cost?
Contact us for a free quote. The cost depends on the cylinder type, size, and the complexity of the installation.
