What would the payback period be for a new high efficiency furnace compared to one that is forty years old?

Answer 1

You can determine your payback time by using your energy bills from the last 12 months. First look at three months during the summer, say June, July, August. Add the 3 months gas bills then divide this by 3. This gives you a average per month amount for the appliances other than the furnace since you do not use the furnace in the summer. Next multiply this average per month number by 12. This is how much you spent on gas for the whole year on every appliance except the furnace. Now add up the 12 months total gas bills and subtract the amount that you figured above for the 12 months of other appliances. This gives you an accurate amount that you spent on just the furnace in gas for an entire year. Now if your furnace is 40 years old it probably has an efficiency rating of 60% AFUE. That means about 60 cents out of every dollar spent on the furnace gas heats the house and 40 cents goes up the chimney. The new high efficiency furnaces are 95% efficient so only 5 cents out of every dollar is wasted out the vent. You can now get bids on new furnaces to check your payback. Say the new furnace costs $2600.00, you can see our local furnace prices at http://www.woodburyheating.com . At the $2600.00 example you can use this to determine the payback. Let us assume a energy bill to use as an example. Say your last years gas bill for just the furnace that you calculated above was $2250.00. This may be a common amount in Minnesota. 95% is 35% more efficient than 60%. $2250.00 multiplied by 35% is $787.50 per year in savings. Using this example the payback would be $2600.00 divided by $787.50 which is 3.30 or about 3 and 1/3 years. Do not forget to take into account the old furnace may break down and the payback would be quicker and how much is peace of mind worth? == == == == guestimating solely on basis of average sear ratings then and now, about two or three years. payback starts as soon as you fire up furnace and go so sleep or leave the house since all new fau's are 100% safer than even a 20 year old unit but if you still have a forty year old unit please use a carbonmonoxide detector. With the new 15 seer units the payback would be approx. 8 years It all depends on the SEER of the unit, size of unit, brand of unit, gas price, etc... But, I would say around 5-8 years. You couldn't know the answer without knowing what your average seasonal temperatures and utility costs are. But consider this. If that forty year old unit breaks in the middle of a cold winter, it's unlikely you'll get the best price. In other words, cheap is expensive. if you take a 60% gas furnace and your gas bill is about 250.00 mth and you replace your furnace with a 92% you will save anywhere around 50.00 to 75.00 per mth also 92% furnaces have a sealed burner section and a lot more safety devices witch makes them one of the safest means of heat out there If your current furnace is 40years old, you have already collected the payback...

Answer 2

The payback period for a new high efficiency furnace compared to a forty-year-old furnace will depend on factors such as the cost difference between the two furnaces, energy savings achieved with the new furnace, and frequency of use. Generally, a high efficiency furnace can offer savings on heating costs, potentially leading to a payback period within a few years.
