Best Oil boiler?

I am searching for the best oil boiler to replace my existing boiler, which is starting to show signs of leaking. I will be renovating the place with more sqft and need to upgrade to a larger capacity unit. My GC will get it sized and installed properly.
Where should I start?
:I know the following:
-I will need 150-250 kbtu/h
Oil heat with baseboards
4 zones
AFUE ??85%-89%??
Any ideas on manufacturers?
OPUS?
Dinkirk?
Ultimate?
Weil-McLain?
Others?

There are a lot of choices out there...
The first step is a room-by-room heat loss calculation and determining what the maximum supply temperatures have to be to get the rooms comfortable on a design-day. Once you have that narrowed down, you can determine whether a low return water temp. oil-boiler makes sense.
However, instead of focusing on a boiler brand from the get-go, I would determine first who the best installers are, find them, and then have them make suggestions based on their local experience on what brands to choose and why. Some brands have better local presences than others and while the presence may shift over time, you have to live with your choice for a long time, have it maintained, spare parts, etc.
Whatever boiler you get, I also suggest you have outdoor reset added on as a efficiency measure if its not already built-in. On the oil-side of the business, I am a fan of the Viessmann Vitola, Buderus G215, and Burnham MPO since all of them can deal with low return water temperatures. That in turn gives you wide latitude with outdoor reset to minimize standby losses and maximize seasonal efficiency.
Do not assume that you'll need a larger unit just because you're expanding. If you're smart and insulate the home as you go, you might find that your heating needs will decrease from the DoE output of the original boiler. In my current renovation project, we increased the habitable space by 30% yet were able to decrease the DoE output of the heating system by over 50%.0 -
Thanks Constantin.. You have been a great help...
