Sorry Rodger I have been very busy, Yes speed the pump up I have mine on 3 and its 90 % butter ! So yes like Yoder said itís better to have it going across the EX several times before it goes out. I was going to put my taco 14 in ( thatís a big pump) but I didnít have time yet . It was 63f  here the other day i was going to do it then but I wound up working all night and the next day. Now itís was 3 here this morning so I donít want to mess with it so yes turn that pump up it will make a difference!

I cranked up the Grundfos 26-99 from it's #1 setting to #3.  I checked on it this morning.  The temp outside is -1 without a windchill.  With 2 zones calling for heat, the oil boiler gauge shows a temp of 150 which is a step in the right direction but not there yet.  I wish I knew what it was if all 4 zones were calling at the same time.  I have some changes I want to make but will not wait until I have the money.  Roger

Sounds like the flat plate isn't the pinch point. It's flow, probably on the incoming line from the owb. I'm assuming that pump is OK? Like a broke impeller, etc.
My thought is- The options are larger underground lines, double pumping, or more emitters in the house so you can heat with lower temp water. I usually favor the extra emitter route. A kick space heater, some Pex under the floor, custom taller baseboard covers to draw more air... Lots of options.
Had one like this last year, eventually found there was a bypass between supply and return on the oil boiler that was left open. Also the temp probe on the Owb was reading about 20 degrees low. Fixed both and problems disappeared.
