Heating Problem
hi, I recently had a bathroom remodel completed. throughout the house I have cast-iron stand up type radiators. it is a forced hot water, natural gas system. my bathroom is small, and the cast iron radiator was taking up useable space. the plumber suggested taking out the old radiator and hooked up a new piece of copper line baseboard to the existing lines.

I am now not getting any heat in the new baseboard in the bathroom, although the other cast-iron radiators in the house are working fine. I do notice that when the boiler kicks on and then off, I get a gurgling sound in the return pipe section of the new baseboard. anything I can do on my own before I call him back in to look?

Check if there's a bleeder valve on either end of the baseboard radiator. If yes, crack it open (usually with a small screwdriver or little end wrench) and let all the air escape, continuing until only solid water comes out (have a pot or something on hand to catch the air-water mix).

If you don't have a bleeder, just give the plumber a call and he should flush the air out for you.

If there is not a bleeder on the end of the baseboard you may want to add one. It sounds like he may have cut in the new baseboard and neglected to purge the system. The gurgling is air and will prevent proper circulation. I found one site that has a lot of heating products the coin vent is the smallest thing that will fit under the BB cover

Those vents you linked are automatic air vents. You don't need that, as there should be an air elimination valve in the basement, and there shouldn't be much air building up in the system. You really just need to bleed it manually this one time, and perhaps every couple years after that AT MOST. So just put in a manual bleed valve. They're about an inch long, and will fit under any baseboard housing.
