Running circulator 24/7/365

[Central Boiler 6048]

Well I just Shut the 6048 down for the summer. Water temp is already down to 107 degrees, I wanted to ask a few questions since this is my first down season with the owb. I have a down flow furnace; my A coil sits on the bottem of my furnace basically on my subfloor, then my water to air heat exchanger above the A coil. the air blows through them and into the ductwork. Should I run my circulater through the summer. I'm worried about the A coil freezing the water in the water to air? It does blow through the heat exchanger first. My second question is if I shut the circulater of should I shut the valves of at the pump flanges or does it not matter? Thanks

If the air go through the heat exchanger before it go through The A coil you want to be sure the fan is blowing when the AC is cooling, You will have no problem. I started my ac 1 year and didn't have the fan turned on and it froze and busted in 5 different places. My A coil is above my heat exchanger in an up flow furnace. Cold air moves down.

If the a coil is below you should be fine, but it doesn't cost very much to run the pump when the a/c is running if your worried about it, you don't have to shut the valves, but it is a good idea to exercise the valves a few times a year. I have seen many times that a ball valve that's been on for years, will break when its 20 below and you really need to change your pump!
