Get more quotes. Buderus is a top brand. $12k sounds way too high, especially if you don't have an indirect fired hot water tank in that price. Do you have Gas or Oil?
'
$12k sounds way too high,'
absolutely. thank you for being a bit of fresh air.
2000 sqft house, absent unusual circumstances, calls for around a 60kbtu box, tho sum may boost that to around 80kbtu. whatever.
that kind of box has a price of between 2k to 5k for a host of good quality choices that should last a dozen or more years, while the gold plated stuff might make it to 15 years.
but for some products squeezed by tight supply, many manufactured products have been coming down, hard, in price recently. word up.
on the udder hand, last month the northeast sent out an sos for diesel/heating oil supply (real bad), and just yesterday eversource sent out another sos on gas supply (real bad).
not at all interested in hearing the whines on carbon inflation since many of youse brought this on the rest of us by your leadership choices.
why, just last week, the germans announced that they're tearing down a wind farm so a
coal mine can expand. look it up.
anyway, normal thinking all around, a 2k sqft house needing a heat only boiler should be around $5k to $7k, all in.
keep looking until you hear that price from a normal source. thankfully, Connecticut is swimming in quality heating professionals. like, almost on every block swimming.
