Hello, I'm looking for some advice on installing a new heating system/method
for my home. First of all, here is my current situation. 45 year old home,
2 floors, each floor has about 950 sq.ft of floorspace, each floor is a
separate unit. All heating is done by an older non-efficient gas furnace
with the thermostat in the tenant's unit (lower floor). The heating ducts
run between the two units, and branch up to the floor registers (upper unit)
and down the wall to the lower unit's registers. There isn't any access to
the heating ducts, except for when it first leaves the furnace. Typical
winter temps have lows of 0 to -5C ( 30 to 40 F) and highs of 0 to 8C (40 to
56F). The lower unit is cooler than the upper, so either the tenant will be
cold or we'll be too hot. The method of heating is very inefficient. Both
units have a wood fireplace in the SW corner of the house (the fireplaces
are not used), and the bedrooms are in the NE corner of the house.
One solution I was thinking of was to install high-efficiency gas fireplaces
in each unit, and turn off the furnace (I'm looking at fireplaces that
output 22,000 btu). This would be good because each unit would have
complete control over their temp. I'm very unsure if this will heat the
bedrooms though: the heat will have to pass from the living rooms down a
hall and into the bedrooms. Can anyone offer insight or experience with
this type of situation? If needed, I can always add electric heaters to the
bedrooms, but that would involve hiring electricians to feed new 240V lines
to the rooms, etc. More $$, which would seem silly have spending up to
$4000cdn for new fireplaces.
Any thoughts or other suggestions?
