Systems 2000 Vs. Buderus G115

My current oil boiler is almost 50 years old and leaks spontaneously, so, it's time for a new one before it fails on the coldest day of January here in CT. I have received 3 quotes so far and I'm tossed up what I should go with. 2 of the boiler people convinced me that the systems 2000 is the best bet, yet, looking around on the forums, it appears like they're not the best quality. Are the Buderus any more reliable?

My best quotes are- (with an indirect water heater)
Buderus G115WS 74,000 BTU $6200
System 2000 121,000 BTU $7800
Buderus G125BE w/ log 2107 72,000 BTU $8500

My house is 1200 sq ft. with new windows and R-30 insulated attic. I think the 121k BTU is a little overkill, but leaves room for expansion. What would you recommend?

Mike, before you even think about 'choices', the very first thing you need to do or have done, is a HEAT LOSS calculation!

Yeah... 121K is more than just a LITTLE oversized... it's probably like FOUR TIMES what you need! Room for expansion indeed! do you have enough property for a 5000 sq ft home?

Do the heat loss, then go back and rethink the choices. Remember that the guys that are looking for your business probably don't care if you spend more on fuel than you have to.

If the System 2000 were a conventional boiler it would be oversized for your house. However, with the factory firing rate the output is 100,000. Also, since the system has a purge cycle, rather than just stopping dead at the end of a call for heat or DHW, the heat remaining in the boiler is purged out to the last active zone.

The result is that even with the system theoretically way over sized, the system efficiency is higher than most systems on the market. All correctly sized boilers are oversized for more than 95% of the year.

The EK 1 is 83,000 to 121MBH depending on the nozzel.


I agree with heatpro that oversizing is not a problem with this system.

I used to be a Sys 2000 dealer.
My most recent install was a small Buderus with Buderus computer. Also a very good system.
