I've got 4 new electric baseboard heaters recently installed and they
each have their own uniquely annoying creaking or clicking that could
drive you mad. Anyone know of any tips on silencing them? Thanks.
Tighten the screws holding them to the wall.
Neither of those is a solution. Especially the first one.
The creaking is probably happening because of the rapid heating and
cooling of the fins in the heater. It's metal expanding again
attached metal. That often happens when using older thermostats, and
some newer ones. The solution I found was to use programmable
Doesn't seem obvious does it? The programmable thermos, once they
initially acheive the temperature setpoint, send fewer AC cycles to
the heater to maintain temperature. Effectively, the feed the heater
less power which leaves the heaters running longer and less hot. That
means the heater doesn't cool off so much, which reduces the amount of
expansion and contraction occurring. It also means they hold their
temperature much tighter resulting in more comfort. And it's slightly
more energy efficient because you're not constantly overpowering a
larger heater when it's not necessary.
Worked for me and people I've recommended it to, but of course, your
mileage may vary. Hope it helps.
Makes sense; although some of those 'electronic' programmable
thermostats can cause RFI (Radio Frequency Interference).
We tried one recently and it caused RFI to a bed side radio two rooms
away when it was tuned to CBC or VOCM. So we have changed it again to
a somewhat more expensive thermostat that does not cause interference.
Other wise we have 40 year old baseboard heaters that have never
noticeably creaked with conventional thermostats.
We were always told 'back then 'NOT' to tighten the screws holding the
heaters to the wall too much. The reason being that the old style
thermostats being an ON or OFF device (No graduation or in between
setting) allows the heaters to expand and contract without noise. Only
occasionally and only when turning the heaters on for the first time
at say the start of the heating season has one heard a slight sound.
Very satisfied with the baseboards we used, unlike some, with the the
ones we chose it is not possible for a child to get their fingers over
the edge and down onto the heating element fins. Also less likely for
something such as the edge of a sheet or curtains to drop down into
the heater and get scorched or burn. In 40+ years we have not had to
replace any of our dozen baseboard heaters. Only replacements have
been one circuit breaker and a couple of thermostats; totalling less
than $100 in maintenance costs.
