Baseboard

Clean the fins on the baseboard (BB) with a vacuum cleaner or brush, make sure the louver is open and confirm that there is at least 2" below the BB to allow cooler air to be pulled in, heated and then vented out the top.



I've seen flooring installed that blocks this space.  Without air circulation, there's nothing to heat.



It could also be that not enough BB was installed to heat the room properly.

not enough heat

is element installed the right way so air can flow through the aluminum fins? was new rug installed? was circulator changed on the boiler and not right size pump installed? Is temp guage on boiler accurate is it really 180* water leaving the boiler? good luck let us know what needed to be fixed to correct the problem.

temps

If this system heated properly last year with the same outdoor temps then You need to check the. return line temperature. If the supply is 180* the return should be 160*.

You could have a restriction to flow. Pump may have a blockage in the impeller.

If the flow is too low then the water looses all of it's heat in the first few feet.

Check your flow...

Pressure/air

Is there enough pressure in the boiler to push the water high enough to fill the system? Is theeree air in the system? Is there a valve partially closed? If it worked before what changed?
