I am looking to replace an existing boiler, the two heating companies in the area gave bids on two different brands of boilers. One is the Slant/Fin Bobcat, the other is a Trinity Ti150. Don't know much about these. Has anybody had any experience [good or bad] with either brand? I would appreciate any input. Both bids were in the mid $8,000 range. A lot of money to gamble with. I live in MI. this system is a baseboard radiant heat on 4 zones. Need some input.
