There are 4 furnaces in my new 18,000 square foot home. Two of which are 100,000 BTU’s each. The other two @ 60,000 BTU’s (properly rated).
Heavy artillery aside… Energy wise my house is extremely efficient. Being equally super sealed thanks to AVENUE INSULATION. One of those rare companies who definitely know how to do it right. Believe me I did my homework, and contracted someone who knows what they’re talking about and stands by their work. And I’m glad I didn’t short cut with the closed cell foam. ‘Cause this stuff works!
But what really drove it home in real world terms, is the unexpected feedback I got from other trades. My HVAC Guys were blown away (no pun intended) not to mention the electricians. They came in when only one of the ‘baby’ furnaces was on in the basement at 20°. The whole house was already heated warm. What better test! Given we had heavy winds and extreme cold temperatures. And my not-so-tiny house is largely exposed on open waterfront. (Recall the freezing days we had earlier this January when temperatures bottomed) To make a long story short…the HVAC guy walked onto the jobsite and as a matter of habit, turned on the 2nd baby furnace to 21° shortly thereafter turning it off. Because it was not required.
By a long shot this is the best investment I made on my home.
