Hi
I am thinking of changing my boiler, the old one is approx. 20 years old and the CH system is microbore the radiator's are new (1 year old). If I have condensing combi boiler fitted do I need to replace the microbore pipework. Thanks in advance.
Regards Harry
If the pipework is adequately sized for your installation, there is no need to replace it.
This may be a good opportunity to flush the system through clearing away any accumulated sediment.
No.
Is the existing boiler a combi? If not, why change to a combi rather than simply having a condensing (but non-combi) boiler which continues to supply stored hot water?
