When it is time for a new boiler
If there are multiple problems with your existing boiler the cost of replacing parts such as the heat exchanger, diverter valve, circulator pump or PCB (programmable circuit board) might add up to a lot of money.
The cost of fixing your old boiler could cost as much as buying a new boiler without any security that another part could fail soon after fixing the current problem.
In this case you may consider cutting your losses and installing a new boiler where you will have peace of mind because a new boiler will have a 5-10 year warranty.

Warning - Fitting a New Boiler to Existing Central Heating
Modern efficient boilers have much smaller components then traditional designs (passageway diameter in boiler heat exchangers used to be up to 1cm and can now be 1mm). This means they are very sensitive to anything that could cause a blockage. If a failure occurs where sludge or debris is found present in the new boiler the manufacturers warranty will usually be cancelled.
Get your boiler serviced regularly
Getting your boiler serviced annually is very important to check the condition of your central heating system. Boiler service costs are not high and a good service gives you peace of mind through the winter months.
Bare in mind that servicing a boiler does not help protect a heating system from corrosion unless the corrosion inhibitor is topped up and unfortunately this is rarely done.
The Industry Standards for Installing New Boilers
All new central heating systems should be pre-commission cleansed as per BS7593 and Benchmark.
This ensures flux residues, excess jointing compounds, mineral oil and other contaminants that can be found in the heating systems following installation are removed.
These can affect the performance of the heating or cause component failure.
It is important when installing new boilers into old systems that all sludge is first removed from the system or this could accumulate in the new boiler and lead to premature failure.
