How to Lower Your Heating Bills

Each year, I see tip lists in newspapers, magazines, and now online, about how to lower heating costs. Usually the information in the lists is the same year in and year out.

Most of the tips are great, but one thing is always missing from them. I'm going to share that with you at the end of this column. You'll be surprised at what it is.

What many of the lists don't do is explain why or how effective the tips really are and what the return on investment is. After all, that's the key. If you're going to spend money to "save" money on your utility bills, then in reality you don't begin to save a penny until such time as you've repaid yourself in lower fuel bills more money than what you spent to achieve the savings. Does that make sense? Here's a simple example in step-by-step format.

I discovered that I was paying my propane supplier WAY TOO MUCH money! Read my April 11, 2021 AsktheBuilder Newsletter for a way to save on your propane bills.

Degree of Difficulty: Two Hammers out of Five.

Step One: Let's say a replacement window salesman tells you you're going to save 35% on your fuel bills if you install his nice efficient vinyl or fiberglass insulated glass windows. Let's assume that the quote for the job is $8,000.00.

Step Two: Get out your utility bills for an entire year. If you heat with natural gas, then this should be pretty easy. Usually the bill is split so you see what you spend on gas and then electricity.

Step Three: Look at what you spend on natural gas for each month over the entire year. You'll spend more per month no doubt from October until April with the highest amounts probably in January and February.

Step Four: Add up the amount you pay for gas for the months of May, June, July, August, and September and divide by five. This will give you the average cost per month for the gas used for your water heater, dryer, range and oven and any other appliance. Realize this is not an exact science as gas rates fluctuate as does your usage.

Step Five: Take this average monthly gas cost and subtract it from each month's usage from October through April. The leftover amount each month is very close to what your furnace or boiler is using to heat your home. For sake of discussion, let's say that for the seven months the total amount you spend to heat is $1,500.00.

Step Six: If the salesman says you'll save 35 percent on your heating cost, this means you'll save $525 a year on fuel costs with the new windows. You'll save this same amount going forward if the winters are the same and not colder or warmer, the cost of gas remains the same and you keep the thermostat in your home at the same setting.

If you do the math, dividing $8,000.00 by $525.00, you discover that it takes a little more than 15 years just to break even not counting any interest you would have lost on your money or interest you may be paying on a loan to install the windows.

Step Seven: This same calculation needs to happen for all the other tips, but since the cost is so much lower for most other energy-saving improvements, the payback time is shorter. The best return on your investment if you're going to do anything is to stop air leaks with caulk, install more attic insulation with great attic ventilation and get a new programmable thermostat you can control from your smart phone.

Step Eight: Here's the tip that you never see in any lists except mine. This tip to lower your heating bills costs you nothing as you already have what you need at your home to do this. Simply wear more clothes when at home and turn down the thermostat to 60 F or even 55 F. If you wear long underwear, a hat and multiple sweaters around the home, you'll be toasty warm at 55F inside. I know because I've done it for years.

Summary: Most people are spoiled and want to walk around their homes in the winter in t-shirts, shorts and flip-flops. My kids tried to get away with that. Just two generations ago houses were drafty and people bundled up and wore warm clothes indoors. My grandfather told me stories about this. Heck, my father-in-law grew up in a farmhouse with no heat other than a wood stove and told me there'd be frost on his blankets when he went to bed up in the attic. You can save big money on fuel, you just have to dress warmer!
