Two series:
100 = Vitodens
200 = Vitola

Also, for the oil fired boilers you don't have to use the Viessman or Buderus control boxes. They are expensive but are designed to give you max efficiency. You can use the same controls to run the ACME boilers to run the Viessmann or Buderus boilers.

However, the controller is where you max out the efficiency as it uses the outdoor reset (which you can get cheaper ones but I wanted the Buderus Logamatic). When outside temps are higher, it kicks down the firing of the boiler as it doesn't need to get as hot to heat the house.

Viessmann has the same kind of set-ups.

I stongly recommend the OP call WinnAir. The aren't just an individual plumber who is comfortable with certain brands. They also have a showroom and can show you the differences between brands. I am not here to sell HVAc equipment but the differences are considerable.

Be careful when comparing AFUE as the types of control such as the Logamatic or Vitotronic make a huge difference in true system efficiency.

In the end, you get what you pay for. All I know is we only used 580 gallons of oil last year for a ~2200 sq ft colonial without even trying to conserve oil by turning down the t-stat.
