How a Gas Boiler Replacement Works

A new gas boiler could save you money on your energy bills, especially if it’s more efficient than your existing one. At 93% – 94% efficiency, only 7 – 6 pence is wasted for every pound you spend on energy, compared to 30 pence if your current boiler is less efficient.

Is it worth replacing old gas boiler?

A gas boiler replacement is a complex job that requires a skilled installation expert. Your engineer will need to cut off water, gas and electricity supply to your boiler room before they start work. To ensure your home is safe, it’s important to make sure any sensitive electronics are shut down before the work begins.

It’s also a good idea to clear out the area around your boiler so the engineer has easy access to it. You should also leave them a space to lay out tools and a drop cloth if you have one. Then, your installer will check the boiler for safety and test it to ensure it’s working correctly.

If your new boiler is electric, the engineers will install an additional electrical supply and hook it up to your radiators. They’ll also clean out the central heating system and adjust pipework to minimise heat loss. They’ll even flush the system with a chemical or power flush to remove any debris and prevent any leaks or cracks. Finally, they’ll test the flue for ventilation and seal it if necessary. Your engineers will finish up by registering your new boiler with Gas Safe and informing local authorities in compliance with Building Regulations.
