As the wall-hung low-eff units like Takagi at $1000 are about 84% and the hi-eff are about 94% you're looking at 10% fuel difference for another $3000 each. That's a long payback to get $200 or $300 in savings a year to pay them off with no guarantee the high efficiency units won't need maintenance and repairs before the 7 or 10 years is up.
I'd rather have units that can be swapped out for $1000 than worry about $4000 units in apartments.
