Looking for some thoughts and opinions on having a 1700 square foot bungalow zoned with the intent of using less gas to heat it.
Thinking of two zones on the main level, one zone for the basement or use as a dump if one is needed.
Easy split on the main...half is bedrooms and bath, half is living, dining and family rooms. Basement is used very little so it could be kept very cool. Basement is insulated and finished.
Demo of the basement ceiling would be required to get the ducting reworked.
Current equipment is Bryant 80% variable, 110K btu.
Heat loss was calculated at 75,000 btu per hour at -40 deg C/F for the whole home.
Insulation is R20 walls, R40 ceiling, triple paned glass throughout...not much room to improve any of this.
Using 200 Gj of gas per year. At current rates, that's $2600 per year.
Two people (I'm one) live in the home. Gas dryer and heated garage that won't be heated much this winter. Wife does not want to turn the heat down much as she's frozen most of the time...you know what I mean. Typical setting is 72 deg F. Home is occupied almost 24/7.
If the house was zoned, would there be any worthwhile savings in gas consumption?
