Why might you need an immersion heater installer?

People commonly search for an immersion heater installer when:

• Their existing immersion heater has stopped working

• They're replacing an ageing or inefficient unit

• They want a reliable backup if their boiler breaks down

• They're installing a new hot water cylinder

• They're upgrading to a more energy-efficient immersion heater

• They need an immersion heater fitted as part of a renovation or heating upgrade

What does an immersion heater installer do?

Step 1: Assessing your existing system

Your installer will begin by inspecting your hot water cylinder, existing immersion heater (if there is one) and electrical supply to check everything is suitable for the new installation.

Step 2: Draining the cylinder

If you're replacing an existing immersion heater, the hot water cylinder will usually need to be drained before the old unit can be removed safely.

Step 3: Installing the new immersion heater

The new immersion heater is fitted securely, connected correctly and sealed to help prevent future leaks.

Step 4: Testing the installation

Once everything is connected, your installer will refill the cylinder, check for leaks and test the thermostat and heating element to make sure everything is working correctly.

What are the benefits of installing an immersion heater?

Reliable hot water

One of the biggest advantages of an immersion heater is having an independent source of hot water. If your boiler develops a fault, you can still heat your water while repairs are arranged.

Energy efficient heating

Modern immersion heaters transfer heat directly into the water inside your cylinder, making them an efficient way to produce hot water when used appropriately.

Safe when professionally installed

Although immersion heaters combine electricity and water, they're designed to operate safely. Having your immersion heater installed by an experienced tradesperson helps ensure all electrical connections and seals are fitted correctly.

What does immersion heater installation cost?

Immersion heater installation costs vary depending on whether you're replacing an existing unit or fitting a completely new installation.

As a guide:

• Average immersion heater replacement: around £300

• Replacing the heating element only: around £180

• High-power immersion heater replacement: around £355

The total price will depend on the type of immersion heater, the condition of your existing cylinder and whether any additional plumbing or electrical work is required. If your existing hot water cylinder also needs replacing, your overall installation costs will be higher.

FAQs

Can I install an immersion heater myself?

Immersion heater installation is usually best left to an experienced plumber or heating engineer. Incorrect installation can lead to leaks, poor performance or electrical faults, so professional installation gives you peace of mind that everything has been installed safely.

Do I need a plumber or an electrician to install an immersion heater?

In most cases, you'll need a plumber or heating engineer to install or replace an immersion heater. If there's an electrical fault or new electrical work is required, a qualified electrician may also be needed.

How long does it take to install an immersion heater?

Replacing an existing immersion heater normally takes around half a day, depending on how easy the hot water cylinder is to access and whether any additional work is needed.

How much does it cost to repair an immersion heater?

Repair costs depend on what's causing the problem. Replacing a thermostat or heating element is usually less expensive than fitting a completely new immersion heater. A local tradesperson will be able to diagnose the fault and provide an accurate quote.

How long does an immersion heater last?

A typical electric immersion heater can last 25 years or more, while the hot water cylinder itself may last even longer if it's properly maintained. Regular servicing and replacing worn components when needed can help maximise its lifespan.

Is an immersion heater worth having?

For many homes, yes. An immersion heater provides a reliable backup source of hot water if your boiler stops working and can also be a practical solution for properties with renewable energy systems or off-peak electricity tariffs.
