Here is the problem. My Taco 2400 20s wb took a S yesterday. I have 330 total feet of 1" pex with a 50 plate domestic hot water exchanger, 165000 btu WTA exchanger with 3/4 ports and 10 90's. I'm guessing around 21-23 of head loss. My delta T was around 30 degree drop +-. I plan on purchasing a stainless pump tomorrow. Any advice is really needed and appreciated. The pump came with the unit brand new installed Nov of 14. I use approximately 177000000 btu in 180 days of the burning season. I'm thinking a Taco 012 will be a good replacement. Any Ideas?
Taco 2400 pump failure. Need some advice on sizing.

0012 won't come close to the total head that you have calculated.
Why not just replace with another 2400?
Sorry, I meant the 011. Looks like a 2400 20 3P would be the closest fit for what I need. I don't want to over size if I can keep from it.
I do, two days before mine went out I helped a friend install an old H5. He had two pumps they were bad so I let him borrow my back up 009. As luck would have it mine went out.
