circulator replacement help needed


I have a 4 zone residential application, 20 year old home with baseboard heat with a new Buderus oil fired hot water boiler.
For an unknown reason, the first floor baseboard does not receive enough heat. It never has, even before the boiler was replaced.The baseboard at the end of the loop is always lukewarm no matter how long the circulator (taco oo7-f4) runs. I've checked the obvious (boiler temp,air bound etc). It's not an unusually long run. On this zone I have 30 feet of baseboard and two beacon morris K120 wall heaters. 3/4 pipe used in the loop and the beacons are hooked up by venturi.
Other zones, even third floor, work well and the baseboard puts out great heat.
To try and solve the first floor problem, I would like to replace this 007-F4 circulator with a model with a lot more flow rate. Taco model 0011-F4 seems to be a good choice. Please confirm or recommend any models or fixes that might be appropriate.

If it didnt work correctly with the old system, what made you think it would with the new one? Why do you just want to toss parts at it like a bigger circulator pump? How about increasing the pipe sizes? Maybe increase the water pressure? Maybe install a duct booster in the flue? How about this one: Call someone that can actually diagnose your problem and get it fixed right the first time? Bubba

Oh goody. Another clueless homeowner that didnt get the answer he didnt pay for. I'll leave you with this little clue dipshit. Doesnt it seem strange that the same little motor that sends water through the pipes up to your third floor and works fine cant seem to do the same good job on a first floor run? Just keep throwing parts at it. You figure it out, asshole. Bubba

The 007 and the 0011 are not that different as they appear on the charts. Go with the next size or 2 up from the 0011. Just a little higher amp draw, but will do what you want.
