While it would be unusual to have three heat exchangers in the attic if they were furnaces, these three were not.
Instead of furnaces, these heat exchangers were all skylights.
This house has been vacant for some time.
I noticed that when the heat was on it did not really heat comfortably, and it has been cold here lately.
There were three large skylights spaced throughout the upper level - in the living room and each of two rear bedrooms.
While they added light, I wondered about them.
Going into the attic space it was obvious that they were all homemade.
Nails were bent, the framing was erratic and not one was insulated!
These aren't skylights, they are heat exchangers!
Remember, HEAT -------> COLD.
So, in the winter, heat in this house is moving toward and whooshing out through each of these skylights.
And in summer, each of those rooms will cook as they heat up and introduce all that radiant heat into the house!
These are not new skylights! You would think someone noticed this effect.
But then, we don't know. Maybe they just poured money into heating and cooling the house!
My recommendation: home improvements sometimes don't improve the house. Be sure you know what you are doing, or hire someone who knows what THEY are doing, when you have improvements done!
