Vented Hot Water Cylinder Installation

What this service covers

A vented cylinder installation is planned around your existing system and hot water demand, then fitted and commissioned so it works safely and consistently.

• Assessment of your current cylinder, pipework, cold water storage cistern and vent arrangement
• Advice on cylinder type and size (capacity and reheat performance)
• Isolation and draining of the system, with safe removal of the old cylinder
• Installation of the new vented cylinder and connection to hot, cold, vent and primary (if indirect) pipework
• Checks and replacement of key components where needed (for example immersion heater, valve set, cylinder stat)
• Leak testing, filling, venting, temperature control checks and commissioning
• Clean, tidy finish and clear handover on operation and basic care

When a vented cylinder is the right choice

This service is most suitable if you already have a traditional vented cylinder and want a like-for-like replacement with minimal disruption.

Common reasons to book an installation include:

• A leaking or corroded cylinder
• Poor hot water performance or slow recovery
• An immersion heater that repeatedly fails
• A property upgrade where hot water demand has changed (new bathroom, shower, or higher occupancy)
• Landlord maintenance where reliability and straightforward operation matter

How the installation is delivered

Work usually starts with confirming the current layout and the best cylinder specification for your needs. The system is then isolated and drained, the old unit removed, and the new cylinder positioned and connected.

Before finishing, the pipework is tested, the cylinder is brought up to temperature, and controls are checked so the system heats properly and shuts off when it should.

After installation: what happens next

You will be shown how to use the immersion and any heating controls, plus what to watch for in the first few days (for example minor air release and where to check for drips). If you are a landlord or managing agent, the handover can be kept simple for tenants and recorded for your maintenance file.
