some pics of nti new tft boilers with touchscreen interface,one with dhw and one zone radiant,one with just radiant 4 zones ,and one 300,000 boiler and 120 gal idhwh replacing a 100 gal commercial dhw and 500,000 btu ci 1961 weil mclean havent removed the ci boiler yet might have to wait till spring.its in a 9 unit building am adding a 80 gal buffer tank between boiler and distribution system,question do you think i could treat the exisiting ci boiler as a buffer tank and tie my supply/return into the addtional tappings on the boiler[provided i can get them out]and not touch the existing ch distribution system[6 units baseboard and 3 in floor copper],that i could do in a long day.cant be without heat for long,i would just shut off burner and remove flue,its just an idea ..thx for suggestions
