Comparison: Veissman, Trinity and Lochinvar gas furnaces

[AWMP]

Can anyone tell me if these three gas hotwater furnaces are comparible in quality and durability. My daughter is looking at the high efficiency models.

I know Veissman but not the other two!

Thanks.

ALL THREE BOILERS IN HIGH EFFICINCY MODELS ARE RELATIVELY NEW TO MARKET IF I'M NOT MISTAKEN THE VEISMANN IS AN ALUMINUM HEAT EXCHANGER IF YOUR DAUGHTER LIVES IN A VERY COLD CLIMATE AREA AND WILL BE ANTIFREEZING THE SYSTEM A SPECIAL GLYCOL IS REQUIRED. I'D OPT FOR THE VEISMAN OR LOCHINVAR EITHER HAVE A SLIGHTLY LESS RESTRICTIVE PASSAGEWAY FOR WATER FLOW. AND MAY BE LESS SUSCEPTIBLE TO WATER PROBLEMS INHERENT IN BOILER SYSTEMS IF NOT MAINTAINED PROPERLY. HOWEVER WHEN SELECTING A BOILER THE MORE IMPORTANT QUESTION OVER THE PRODUCT IS THE INSTALLING CONTRACTOR. MAKE SURE YOU GET ONE THAT UNDERSTANDS HYDRONICS , PUMPING AND WITH ALL NEW HIGH EFFICIENCY MODELS WATER TREATMENT.
