Had the HVAC guy out yesterday to go over my furnace, makes my wife feel better. Anyway he was looking at my system asking questions and he asked one I couldn't answer. He wanted to know why the water pump on my boiler wasn't tied to my secondary thermostat that runs my blower on my furnace during the winter? He thought it would keep the water warmer staying in the boiler outside vs circulating all the time when the blower was not in use. Told him it might have to do with keeping the water all the same temperature but really didn't know. Help me out guys!

If you have decent pipe the heat loss by running the circ is very minimal, shutting the circ off would only cool the lines off and when they come back on it will give a blast of cold water back to the boiler, also the circ on an open system will last much longer by letting it run , power consumption should be between .75 and 1.5 amps to let it run.

Yea and with most systems that's the only way to make your plate or side arm heat exchanger work properly.... There is many reasons behind it.

Great points that I totally forgot. Thanks

So it is good practice to keep your circulating pump running 24 7 right? Just making sure I have read mixed things. Thanks guys

I'm sure circulators don't have em, but something to consider on larger single phase electric motors, every time you start a motor, thats one less time it going to start. Larger single phase motors have a centrifugal starter switch in them that will go bad eventually, most electrical components life spans are either rated in hours ran or cycles.
