replacement boiler recommendation

[southern engineering]

I would appreciate recommendations on a good quality and efficient replacement residential heating boiler by brand and model that doesn't cost all of my beer money for the next 20 years.  The home is two story, has an unlined brick chimney in excellent shape, baseboard heaters, two line voltage thermostats which run two (1 1/4 inch inlet each) pumps one for upstairs and one for downstairs, and is 2,100 sq/ft.  The original boiler is a Crane Sunnyday model 15-5, water net IBR rating 114,000, B-R burner capacity BTU/HR 190,000, Max WP water 30 lbs., Valve Cap LB/hr 168. and is running on natural gas.

Pensotti is the best value in the industry.Im getting 88 pcnt right out of the box non condensing.Oil of course, but is also available in natty gas.US importer is CRD  Energy out of Bangor, me. Johnstone supply can hook you up. At the wholesale end its abt 15 pcnt cheaper than Biasi, (also a fine boiler) I have been installing them since 1982 or so. Great boiler good value.
