Replacing an Immersion Heater Cost
Typical cost of an electric water heater replacement
Although most UK homes only use immersion heaters as a backup source for hot water, they can be incredibly useful during the summer months when the central heating may be switched off but hot water is required. Electric immersion heaters are simply water storage cylinders which are heated by an electric coil and can provide hot water independent of the central heating system. Depending on the size of the water storage cylinder may be up to 3 electric heating elements inside.

Things To Consider When Replacing An Immersion Heater
If hiring a plumber to do this job for you then you should look for proven track records and also ensure that they are registered with a professional trade body and have a checkable work history. It’s also a good idea to check that they are fully insured and offer a comprehensive guarantee on their work. This job will typically take 1 to 2 hours depending on the ease of access and whether or not the immersion tank needs to be completely emptied. When it comes to choosing a new electric heating element, make sure that choose a new element of the same size, shape and power rating.
If you have a spanner which will fit the heating element, it is not too difficult to do this job on your own as long as you have easy access to the water cylinder. But you will probably find in most properties the hot water storage tank is hidden away in the most awkward of spaces!
Doing it Yourself
If you decide to replace them yourself then you should know that you will often have to drain the tank before replacing the heating element which will increase the time taken for this job. You may be lucky and find just the top element needs replacing so the tank may not need to be completely emptied, but sod’s law dictates it will be the bottom element which is defective!
Do not attempt this job as a DIY project unless you are 100% sure that you have the skill level and confidence required to complete the job safely. Make sure you have all the correct tools required, in particular a special spanner which will likely be required to fit the immersion heater.
