I have a Navien natural gas tankless hot water system that also provides the hot water for my baseboard heating system. I love it. The system is very quiet, uses outside air for combustion so you aren't sucking in air that is already heated and it is very efficient.
If you have a small generator you can run your heating system during power outages.

I think mine is a CH210 rated at 175,000 BTU
I am actually on my second unit, it is interesting that you ask about noise. The first unit that I had was kind of loud and it made sort of a whistling sound but I thought that was normal. After about a year and a half the unit died, it burned a hole in the heat exchanger outlet. There was no leakage into the house because internal sensors shut it down.
My HVAC contractor replaced the whole unit with a brand new one at no charge and the new one is a lot quieter than the old one so I think the original one was defective
Original one was installed Nov 2011
New one installed May 2013

My grandpa in NY is running a Bosch, but I know he also has solar panels that do the majority of the heating. Last time I went to visit he seemed rather impressed with it and had no complaints. I know this doesn't help at all, but I thought I'd throw it in there.
I really like the Navien. I think it is over 90% efficient but I can't compare the cost of operation with other gas units because I converted my house from oil heat to gas heat. All I can tell you is that I am glad I did the conversion, gas heat is waaaay cheaper than oil.
