I'm wondering if i can get more out of my plate HX i use to charge my storage. My system consists of a 20 plate HX with a grundfos 15-58 on the storage side running on low speed and another 15-58 on the boiler side running on medium speed. I run batch burns in my boiler and while firing my boiler stays about 10-20 degrees ahead of my storage until the fire starts dying down then they balance out at alittle lower then I'd like (about 165-170). Is there a better way to run my system to keep the storage alittle closer to the boiler while it's in the peak of the burn? Would delta T pumps help with this?
