Immersion Heater Installation

What immersion heater installation covers

A practical, safety-first service to get your hot water cylinder heating reliably.

• Site assessment of the cylinder, existing element, controls and electrical isolation
• Advice on the right immersion type and rating for your cylinder and usage
• Removal of the old element where possible and installation of a new immersion heater
• Replacement of key controls where required, such as thermostats and high-limit cut-outs
• Checks for leaks, correct sealing, and sound cylinder connections
• Electrical testing and confirmation of safe isolation and switching arrangements
• Commissioning, functional testing and clear handover on use and settings

Who this service is for

• Homeowners with no hot water or intermittent hot water from a cylinder
• Landlords needing a dependable, safe hot water setup between tenancies
• Small commercial sites using cylinder-based hot water (for example staff kitchens or washrooms)
• Properties with an immersion used as a backup to a boiler, or as the main heat source

What happens during the job

The engineer will confirm the cylinder type, isolate power and water as needed, then remove and fit the immersion heater using the correct seals and torque. Controls are set and tested to make sure the thermostat operates correctly and the safety cut-out trips if required. For unvented cylinders, the work is carried out with the correct certification and with attention to the associated safety devices.

After installation

You will be shown how to use the immersion safely, including recommended temperature settings and how long it should typically take to heat. If the cylinder shows signs of wider issues (for example failed valves, scaling or wiring faults), you will be advised on the next steps before problems escalate.
