I have a 275 gallon tank, would it be worth adding it for storage? This would double my water capacity. Also I have a taco 0011 pump, would this pump be enough to pump into the tank an back to furnace?? Or would I need to add another pump on the return side? The furnace is about 70ft from the house an its a mahoning owb.

i  think your pump would be fine and i think if you try it you should pipe it so you could bypass the extra tank if you so desired.

there are many ehre (including me) that think as far as the water is concerned, more is better  bu ti would still pipe for the bypass in case you find it is not exactly what you were after (best to keep all options open)

Is 275 gallon tank big enough, or should I find a bigger one? The main reason I'm doing this is to heat my inground pool. It's 25,000 gallons or more. I tried heating it last year an it really worked the furnace hard, hoping this would help??   My plan is to put the tank in my basement, have my pump at the furnace pump the water threw my heat exchanger for my house heat an dump into the tank, then return to furnace.  My mahoning has heating coils in the back of it for dhw, an one for the pool. I'm gonna mount them in the storage tank then.
Hope it works.

I would think it would be a step in the right direction.Not sure if it will be enough though.

I don't think it will help heating a pool. The usual reason for more water storage is to get longer burn time and longer between cycles. If you have a steady load on the boiler like a pool and it running continuous it won't really do anything.

I agree with RSI. It wouldn't hurt anything, but in the big scheme of things, it wont do any good either. If you do put that thing in your basement, insulate the crap out of it. In the winter it won't matter much, as the heat radiates up, but the summer is a different story, in that heat still rises, and you will really notice it then. My friend across the state has an Empyre Elite in his basement with two stacked 500 gallon tanks that have been sprayed with about 3" of insulation, and even with all that foam, they give off a boat load of heat in the summer.

It wont change a thing.  The only time more water makes sense is like with a euro style gasser and you want to heat 2-3k gallons of water up to 205 and pull heat from your storage  couple days without having a fire.

I have a pool too and it is 25K gallons.  I do not think you are going to store enough to heat the pool unless you have a very large tank.  I do not know yours, but mine takes a huge amount per day.  Something like 500K BTUs.  I was having issues myself with my CB6048.  The problem being the load is 6-8 hrs and the unit just doesn't recover fast enough with a constant load like that.  My water temps were dropping into the 160s before it would recover.  I recenty got the blow upgrade for it and that has made a huge difference.  I have not seen it below 178F now.  It also burns much lower before needing wood.  I used to have to have some logs in there to get it back to temp.  Now if can work on coals alone no problem.
