I have two good installers, one who wants to put in a Buderis, one a 3-pass weil mclain. Which would you choose?
It's a 1950's cape, oil, hydronic system. The cost differences aren't a big deal.
Also, has anyone ever had any luck with a geothermal system in an old house? I know new construction is the usual condition for installation because you can make the house really tight, but does it ever work on an older house?
I live in New England, with a 1700 s.f. cape.
Thank you for your help!
