Pumps should hopefully last longer than that - but may not. I can only
remember replacing mine 3 times in 38 years - and in two of those cases
the pump hadn't failed but was changed for other reasons.

First pump lasted 30 years, replacent because new boiler was fitted 6
years ago. Current pump is 6 years old.

My pump was installed, by me, in 1988.

Pump in my late parents house was installed in about 1965 and failed
within a year, the replacement is still running! It is slightly more
robust than the average domestic pump, but even so quite amazing.


I don't know, but AFAICT the CH system here was probably installed in
the 1970's, though maybe the late '60's. It looks like it still has the
original pump - a large and sturdy Grundfos
