Now Ottowa may get cold, but unless you have had problems with your
heater not keeping up, you do NOT need a bigger furnace. The guy is not
up do date, to be polite. A larger furnace is always, always, less
efficient when its output is not needed. As a matter of fact, if they
are quoting input btu's, you could get by with a smaller furnace,
although I don't think that would be wise in Canada, unless you are
counting on Global Warming..
With furnaces bigger is not better. Get a real heat load calc done.

So they could be quoting either input or output?
When I said "Sorry" I thought one person had agreed with m Ransley,
but both posts were from him, so it only counts as one. :~)

Thanks for setting me straight, you and Greg. I didn't want to
confuse anyone and I hope I haven't.
I'm very glad to get this straight myself because I'm going to need a
new furnace myself someday, and yet I can't get myself to start
shopping as long as the current one works. Yes, I'll regret this when
the time comes, but at least now I won't waste one cycle of shopping
by confusing what the btu rating is for.
Yes, I can see how that would be just fine when everything was 80%.
but now that I know, it's not much harder to multiply the input and
multiply by the percentage.

Last year Carrier Infinity 2 stage VS DC motor furnace installed by Direct
Energy cost 4100CA$. + new Aprilair 600 humidifier 250$ installed. + GST
Plus 300$ Endbridge rebate. Plus expecting more rebates as I did home
efficiency audit before installing furnace, and submitted results just now.
If you go with DirectEnergy, you have to pray that they will send you a good
crew (they have many, and some of them have no clue what they are doing).
My old furnace was 120BTU, new is 100BTU - more than enough for my 3700sq
feet home + basement.
A year ago I was quoted difference in price between 100,000BTU furnace and
120,000BTU furnace around 75$.
