Good Modulating Boiler for NG

Don_175

I want to replace our boiler with a new NG unit. I have read alot about these new modulating boilers like Weil-McLain, but I have also heard to stay away from ones with aluminum heat exchangers because of corrosion issues, especially with NG.
Is this really an issue? If so, which ones have stainless steel? We have a system with fan coils as well as one small radiant loop.
Thanks.

Are you looking for condensing or non-condensing? The price difference is quite significant. For non-condensing I would go with the Baxi Luna http://www.wallhungboilers.com/luna310fi.html which are solid units. There is a condensing version of this that has just been released so reliability has yet to be proven. If cost is no concern i'd go with the Vitodens http://www.viessmann-us.com/web/canada/ca_publish.nsf/Content/Vitodens200_ca_english Vitodens everytime, proven reliability, warranty, and support miles ahead of everyone else.
