What do electric boiler installation and repair services include?

This service includes all the tasks needed to get your electric boiler working to provide hot water in your home, whether it’s a new installation or fixing an existing one. This can involve removing the old water heater to make way for the new installation.  

Other tasks can include positioning the tank, installing pipes, connecting the expansion tank, connecting the temperature and pressure valve, and attaching the electrical connections and wiring. Your handyman can also repair damaged electric boilers.     

Removing the old water heater

Some boiler electricians can remove an old water heater to make way for a new one. Your specialist begins by cutting off the power and shutting off the water at their mains. A bucket is used to catch any water stored in the boiler that will pour out of its pipes. They can then detach all the pipes and connections and transfer the old boiler tank to a storage area. Some electric boiler installers may offer to dispose of the old tank for you. 

Positioning the new electric boiler

Your hired boiler specialist can determine and place the boiler tank in the most appropriate spot in your basement, and centre them on a raised platform for easier access and as a safety measure against flooding. If you don’t have a raised platform, some specialists can make one for you for an additional fee.  

Fitting and installing pipes

Next, your specialist installs the pipes. They measure the pipes and cut them to the right widths and lengths. They can remove the burrs on the lip and inner portions of the pipes to ensure better flow. Each pipe installation is wrapped with plumber’s tape, soldered or installed in both methods when necessary, for additional safety and protection against leaks.  

The appropriate components like compression nuts, rings and flexible hose are likewise installed; your specialist ensures that all these installations have a perfect seal and a tight fit.   

Attaching the expansion tank, temperature and pressure valve

Your boiler installation specialist attaches the expansion tank to the cold-water supply line next to or above the electric heater. The pipes they install are cut to the right lengths, deburred and soldered as needed. Your specialist can match the pressure of the expansion tank with your water line’s pressure using a handheld air pump once the expansion tank is installed. They finish the installation and seal the tank and pipes with soldering if necessary. 

Attaching electrical connections

With the power and water still off, your specialist attaches the electrical wiring of the boiler to your main circuit breaker. Once all installations are done, they turn the water and power on and test if the water in your spigots run hot.  

Repairing a damaged electrical boiler 

If you need an electric boiler repair service, your specialist inspects the boiler with the power and water shut off. They check for leaks in pipes, joints and fittings, pressure imbalances or other issues and do the appropriate fixes.

Boiler Repair & Changing Light Switches - URGENT


South Norwood, Greater London

4th Feb 2020

I need someone who can assist with my boiler and changing light switches in my bedroom flat in South Norwood. Boiler: Worcester Greenstar 24i Junior Yesterday the boiler started making noises and was leaking heavily. I called out an emergency plumber who was able to stop the leak temporarily. I need this fixed permanently and urgently as there is currently no hot water or heating. To fix it, it will need parts (not sure what, I need you to advise that). I need someone who can come tomorrow (Weds) ideally after 5pm to look at the boiler and determine what parts are needed so they can be bought and job done and finished by Thursday (any time on Thursday will be possible). I need someone who is experienced with Worcester boilers or very experienced with boilers in general. Light switches: Changing two dimmer light switches to the kind that operate by remote/touch. Should be a quick job for an experienced person.

If there was an option to rate 10 stars, that is what I would have done. Thank you for being so reliable and professional. I would certainly use your services again!
