Bought new house, all the old houses we've
lived in were either forced hot air, or old
steam type radiators.
The new one has hot water baseboard heaters.
They seem to work fine, no complaints.
However, at night you can hear some slight
noises coming from the baseboard radiators
when the circulator pumps are running. Odd
little periodic metallic popping noises.
Having "Google'd" the topic, it seems this
is normal to a degree (the slight expansion
& contraction due to metal heating up and
cooling down - and that's what i'm hearing).
Does this correspond to what others of you
with this type of system in your home experience?
