Well, you can install a larger pump like the 0010 suggested to heat your entire house to try to make the pump heat the water instead of the boiler. However, an 80-gallon tank needs 80 x 8.33 x 70 = 46,000 btuh in an hour which is well served by the 007 pumping 7 gpm which it can do easily. Putting a larger pump on the tank won't make the tank heat exchanger accept more than 70,000 btuh input which requires 7 gpm that the 007 provides easily. You might try driving to the convenience store with a HumVee to get milk; but it won't get there and back faster, neither will changing to a larger pump.
