If your current yearly heating bill is $1000 and you have an 80%

$800 is used for heat and $200 is wasted out the exhaust.

With a 95% efficient furnace,

$800 is still used for heat but only $42 is wasted out the exhaust.

Your yearly heat bill drops to $842 yielding a $158 per year savings.

Over the next 15 years you'll save $2370 in fuel. *If fuel prices go up,
you'll save even more.

Can you really afford an 80% efficient furnace?

Of course not but what bragging rights do you acquire by making a
sensible decision?- Hide quoted text -

This is a classic. You're the guy telling us that the consumers
are too stupid to make the right choice for their own furnace. And
yet, here you are chiming in that it makes sense to shell out the
money today to replace a furnace that's 80%, because you
can't afford not to? Let's do the math. Replacing that furnace is
typically $4,000+ and that money would be spent right now.
The alternative 80% furnace in the above example only costs
$2,370 in additional fuel over the next 15 years. Factor in the
time value of money and the comparison only gets worse. I cou;ld
take that $4,000, invest it in the stock market, and history shows
you'd likely get an 8% return, exceeding the savings in fuel.
And given that most people here seem to agree that a new
furnace today has about a 15 year life, it would NEVER pay
for itself in fuel savings.

Yet, you say it's J Q Public that's too stupid to figure out
what to do and needs the govt to do it for them?
