Is there a way to figure out an exact cost savings made by upgrading equiptment/insulation etc? Anecdotally, my parents upgraded to a 95% furnace last year, and are seeing the savings, but it would have to be compared to the HDD for each year, correct? And even at that its something of a crap shoot since they have a gas water heater as well? One would need to moniter volume of gas at the furnace, correct? is there any sensor for this?
