Well much to my wishing otherwise I have to replace my furnace. It’s not serious at least right now. I have some hair line cracks in a few pipes, so at least I can shop around a bit before getting it replaced.
We have a few quotes in and I’m now just trying to decide if the extra money to upgrade to a two stage high efficiency furnace is worth it. The price difference between a 80% efficiency two stage and 92% efficiency two stage is $850.
I’m not sure my exact spending on gas for a full year, but I’m estimating around $120/month. So over a year that’s $1440. Therefore a 12% difference between the options would mean a savings of $172.80/year or a payback period of (850/172.80) 4.9 years. Not a bad payback for a capital expenditure and since I’m planning on being in this house for around 10 years I should do alright over the longer term.
While researching my options I did come across some other good ideas on saving heat. Did you know for example that you can often improve the distribution efficiency of your heating system by around 20% by just buying some foil tape and going around your heating system in the basement and fixing all those little air leaks between duct sections? Another good one is installing weatherstripping around your doors. For those with a bit more time on their hands you can enter your attic and plug all those little holes around your light fixtures and wiring as they make your ceiling like an over sized piece of swiss cheese for heat loss. While your up there you might want to consider upgrading your insulation. Just a few ideas for you.
