As time goes by, boilers become old, temperamental and generally very unreliable. This leads to frequent break downs and eventually a new boiler replacement is required. New condensing boilers are far more efficient and reliable.
So if your boiler is old and unreliable we highly recommend that you consider replacing your existing boiler with a newer model. With greater efficiency a new boiler will help to bring down your heating bills, transforming the energy efficiency of your home in the process.
