We have an energy efficient (by 1987 standards) 2,000 sq ft contemporary in NH with 2 zone baseboard hot water heat and tankless hot water coil. Our Burnham V-714T cast iron oil fired boiler is on its last legs (internal leaks), and our trusted oil supplier/HVAC installer has recommended either a steel New Yorker boiler or a more efficient cast iron Weil-McLain for 20% more.
We're told the steel boilers are now as durable as cast iron, if not quite as efficient.
1. Opinions on steel vs. cast iron, considering the price differential?
I also asked about a load calc, and was told that we would be getting the smallest boiler made for the application (90,000 BTU's if I remember right), and if a load calc recommended something smaller there was not much we could do if we wanted to stay with the current oil and baseboard hot water set-up.
2. Does this sound like reasonable advice?
Thanks for any help and advice you may have, all I know so far is what I've skimmed off these forums in the past day.
