We just got the results last week. It looks like the heat loss (62,022 BTUH) is over twice that of the heat gain (29,842 BTUH). Is this average, or is it just part of having a 165 year old house?
Given those numbers, our geo guy is telling me that we need to couple the geo system with a backup heat system. Now, I've never heard of geo needing a backup. I'm assuming that because of the load calc, if we size the unit for cooling, we won't have enough tonnage to provide the necessary heat? And if we size it for heat, it'll be waaay oversized for cooling, yes?
We currently have an ancient oil furnace with separate AC. I'm wondering if that's why. Geo's expensive enough that I want it to be able to heat and cool without backup.
What do you all think?
