Im not sure what size boiler you need, but one thing the Buderus G215 has that Im not sure exists in the Crown Freeport CT is built-in thermal shock protection; no bypass or mixing valves are needed to protect against thermal shock and condensation. Makes for a longer-lasting boiler.

Whattya thnk of Corwn boilers?? (NM)

The CT series is our choice for oil. The price and value makes it a great choice.

oil boilers

If the boiler is for oil go with the easiest to clean and service go with a buderus not much more money and super high in value and no combustion chamber to replace ever and no jacket to remove to clean higher insulation valve jacket the list goes on and on and as for a gas job buderus direct vent modulating boiler gb142 or a htp munchkin top shelve stuff without the high of a price for all the engery you will save yourself good luck and peace clammy

That's

a scotch marine, right? Do you know anything about the Tobago? It's the regular wet-based design. Do you use chimneys, or power vents? Do you use the stackable water tank? Or a coil? Riello or Beckett?

Thanks

I agree

I have a Buderus oil boiler with Crown mega-stor indirect; good setup the value of both is really great. Also the logamotic controls on the buderus is a big bonus for energy efficiency.

Great unit and same design as Buderus. If you don't use direct vent then they don't have any chamber or refractory either. If no chimney then use Tjernlund Sideshot for trouble free operation. I have numerous ones in servie with Riello no problems with eff 85-88%.

I have installed 3 so far, nice unit. There is not a 3/4" tapping on the bottom for a boiler drain like WM has.

Thanks all

and keep em coming.

Not too sure about that

I have been using both Buderus and Crown boilers for many years and I would never hesitate to install either, lately I have been using Crown instead (when I can't sell the Viessmann of course) because I like the reps, and it is a few bucs cheaper than the Buderus. The CT series block is manufactured by Viessmann, so you know that this is a great boiler. I only buy Crown boilers w/ Riello burners, and I stay away from using the direct-vent model, using a Tjernlund side shot instead so I never have to worry about replacing combustion chamber linings. I really like the easy service, and clean burning charactaristics. The few things Buderus has over the Crown CT is better controls (that is what Tekmar is for), and I think the Buderus looks cooler. But in the end it is personal preference I think.

As far as condensation protection, Buderus use to require 120 degrees F minimum on the return on the G-215 Thermostream, but now in the last year or two I am hearing from the reps not to worry about return temperatures....hmmmmm I would still install some type of return temperature control on the Buderus boilers to keep the return temps at least 120 degrees F. But that is just my opinion, in some cases when using a boiler for low delta T diff radiation like hot water fancoils, and an indirect there really is no worry about condensating.. That is why I see what my application is and decide which boiler to use based on the application, instead of my personal preferance

Joe @ Buderus

Sometimes Joe at Buderus reads this forum; I would ask him to explain the Buderus design for thermal shock protection; or just call him at Buderus in NH.

Buderus claims it on their web site pretty clearly.

The crown also prevents thermal shock

didn't mean to question your knowledge

I know that the factory states this fact in the literature, I am just skeptical by nature. The way Buderus controls thermo shock is to mix some of the outgoing hot water with the return water where it enters the block. I just wonder what would happen in a prolonged condensating condition, like snowmelt without low return temp sensors or primary/secondary piping. We are all here to learn from each other, lets see if someone can answer this....
