I just bought my first house 6 months ago. 2 stories, 3500 sq ft with a Burnham series 2 boiler. It was a forclosure and the company didn't winterize the pipes. So we had some people fix the pipes that we co.uld tell are leaking. This was when it was still warm out. When I first needed to uset the heat, I couldn't get the upstairs zone to heat up. I thought it was a prob with the valve- so I replaced that- It open and closes fine. So after driving myself crazy I finally stopped and thought about pressure! I must need the pressure higher to account for the upstairs zone to work. After raising the psi to 30 it worked. The only prob is it won't stay at 30 it always goes back to around 20. Shouldn't the presure stay the same once you have it to the pressure you want? Anyways - I found another leak 2nite, so I flushed the system and fixed the leak. Now I can't get the upstair zone to work again. I got all the air out of the system! Here's my thought- with air still in the pipes will that cause the real psi to actually lower? Therefore not having enough press to make the hot water flow to the upstairs? Or am I completely off- does the circulator make the water flow through the pipes? When I try and get all the air out should I start from the basement and work up or the opposite? The people that fixed my pipes said to never go above 20 psi but the h20 won't flow upstairs at the amount? Thanks any ideas would be awesome!!!--- MIKE

I have a New Yorker, 20+ years with ABC burner. Serviced every year, runs fine. Ranch house with second zone in basement. R8182D aquastat and Taco circulator. Aquastat and zone valve changed recently. I have heat, but it's pretty lame. I think it is substantially less than I remember. All baseboards are warm, but no "oomph" to air coming out, just kinda drools out of baseboards. My boiler runs almost constantly between low/high limit to keep house at 70 deg. I used to be able to get this place so hot I would have to turn on air conditioner (joking but you get the idea). Everything seems to be working ok, limits set at 190/160. Now I can hear the circulator pump upstairs (sounds like someone has the faucet on). I have asked 2 diff techs during servicing, and they say it's "normal". BUT, I don't EVER remember hearing the circulator for last 10 years until this year. I thought maybe pump was bad, but they say "no way, they never go bad". They also say if I had a bad pump, I would have no heat at all. One tech opened my return line just ahead of circulator ( I have no convector bleed valves) for less than 1 minute, and said there was no air. SO, if I have no air, and pump is good, and water is 190 deg, how come no heat? Driving me nuts, cause my heater is cycling every couple minutes (in PA, so it's cold now). This system was capable of getting house to at least 76 in past. Now I'm lucky to get 70. I have to get unit servived twice a year now cause it runs so much. Appreciate any help. Should I just try replacing circ pump? If you replace cartridge, does this change impeller also? (tech says no, I doubt he is correct, seems foolish to not include impeller) Is it possible the circ pump is running backwards (was disconnected during new aqua install), or is this fixed (pump housing hasn't been removed). Thanks in advance, Ed
