Taco 007 bf5j

I just got a new woodmaster traditional 4400 stove my loop will be about 125 ft. with a plate heat exchanger and 200,000 btu heat exchanger in it I was wondering if the taco 007 bf5j pump would work for this ?

"work"? Sure. Work well? Absolutely not. A 4400 needs about 10-12 GPM of internal flow to stay happy and an 007 on that loop (assuming 1" line) will flow about 3 GPM. Assuming the plate HX is for DHW and the space heating load is anywhere near 200k, you're going to need 15+ GPM to feed it and a 4400 is too small anyway. We need to back up the bus a little bit here and figure out your actual heat load before we start sizing a circulator. What are you heating and what size lines are being used?

I'm heating a 2000sq foot trailer not very good insulation it's a 87 model I'm going to have a second loop going to a 1000 sq ft shed going to a 75000 btu heat exchanger it's about 200 ft loop I'm using all 1" pex

I would recommend a Grundfos 26-99 on both circuits. They are expensive compared to an 007 upfront, but in the long run it'll save you thousands of dollars and a whole lot of stress just to have it done correctly the first time. Make sure both circulators are mounted inside the rear cabinet of the boiler on the supply line pushing toward the buildings- do NOT mount them in the building under any circumstances.

Thank you for the help I'm going to get 2 of them for my loops

Update i ordered the wrong heat exchanger the one I needed is 140,000 btu do do i still need the grundfos 26-99 pump

You don't "need" anything, but a 26-99 is still ideal

Ok it's supposed to be delivered tomorrow got everything ready to go except treating and filling the tank and starting a fire
