Good evening all,
I have been making great progress in preparing for the arrival of my new OWB. Check is going out tomorrow so we are getting close. Pipe is underground and grass seed is growing well. Concrete pad is poured and curing just fine. Now my questions...
For those who have hooked the boiler to an existing hot water boiler using a plate exchanger...I have two circulator's on my existing boiler that pull the water from my hot water baseboards and my radiant floor heat. Where would be the most logical an efficient place to tie the plate exchanger in? Will an oversized plate exchanger hurt efficiency? I'm looking at a 50-60 plate. House is 2000 sq. ft. and I have a domestic coil in my existing boiler. New OWB will have 250 gallon water jacket and I will be running a 3 speed grundfus so I can dial in the proper GPM to the plate exchanger. I will be installing a series of temp guages on both the supply and returns going to and from the plate exchanger. The existing boiler has 1 1/4" black pipe that I would have to tie into. Any thoughts or pics of some existing hookups would be helpful. Am I missing anything important?
A picture showing my current boiler setup:

I got me a lot of seasoned wood to feed my OWB properly:

And more wood waiting to be butchered over the summer:
