Replacing gas boiler

[GreaseMonkey]

We need to replace our 1980's Vaillant gas boiler. We have hot water baseboard heat with a mix of fin tube and cast iron. When the boiler was working the water temp was set at 180 degrees and we had no complaints. The boiler is located in a closet in a room that would be nice to be able to use as a bedroom. Hot water tank is in the same closet, gas fired 50 gallon tank that is 8 years old. What is the longest lasting, least maintenance required and quietest boiler that is the safest in a bedroom? We could provide sealing doors on the closet or any other safety measure. Draft venting, direct venting, cast iron, mod-con are all options. There is no drain in the closet or nearby for condensate. A pump would be required for condensate as this is located in a half basement. House is 2,400 square feet, well built 1960's home with new windows. Welcome any comments or suggestions.

A 2400 sqft it's hard to believe there isn't a better place. Any garage?

My brother's vacation home in VT has a Buderus tankless boiler that heats the home. It is very quiet requiring direct vent to the outdoors. The real problem is the plumbing, circulator, expansion tank, etc. All boilers must be connected to the houses water via a reducing valve and a micro bubble fixture. If there is a crawl space, then it's doable. If you do this conversion, be sure to install a carbon monoxide alarm.
