Looking for advice, and sorry that as a home owner, I just don't have the background to make any sort of technical assessment on this. Our Burnham Revolution is 16 years old. The transformer blew last week, and some sort of card/motherboard died last winter. Our service tech said that it's time to replace, and quoted ~$ in immediate repairs to "maybe" make it through the season. So, what are your thoughts on a 16 year old Burnham Revolution, and at what point is it time to replace? Also, the tech offered a "pays for itself" concept for a new Bosch...is that crazy? I'm trying to wrap my head around how a 15% or so improvement in efficiency turns into $ over 15 years or so. Thanks!
