Hoping to get some advice. We purchased 3 bed semi-detached house. The radiatiors are fed by 10 mil microbore piping. Should this be changed or is it okay to keep the pipes and just put in new high efficiency radiators?
Microbore is very unusual in Ireland. Just make sure when refilling to put in the correct corrosion inhibitor to ensure pipes don’t clog up. In fact you might want to look at getting the pipes flushed if it’s a very old system.
