Improving the Efficiency of Your Oil-Fired Heating System

Lower your energy costs, still enjoy unparalleled winter comfort.

Have you arranged your start-of-the-season heating oil delivery from FSi Oil Services? If you haven’t, we suggest you take care of it right away. The last thing you want to do is kick off the heating season with a tank run-out.

Fall is also a good time to do some prep work to boost the efficiency of your home heating operations. In this article, we will provide you with some easy ways to lower your winter energy costs without sacrificing your family’s comfort in the process.

1. Keep Up with Filter Changes and Radiator Bleeds

If you have forced-air equipment like a furnace, check your air filter monthly during peak heating and cooling seasons. A clogged filter restricts airflow, forces your system to work harder and lowers your heating efficiency. If you use a boiler with radiators, bleeding them once a year also helps keep heat circulating efficiently. These simple maintenance steps go a long way toward reducing energy waste and improving comfort.

2. Get More from Your Ceiling Fans

Did you know ceiling fans can help lower your heating costs? Just flip the switch to run them clockwise on a low setting during the cooler months. They will help push warm air back down into your living space, making you feel more comfortable without cranking up the thermostat. Even a small adjustment like this can help you use your furnace or boiler less and cut heating costs by a couple of percent each year.

3. Harness the Power of Sunlight

Take advantage of free natural heat by opening blinds and curtains on sunny afternoons. Letting the sun in helps warm your home naturally, so your heating system doesn’t have to run as often. Also, remember to trim shrubs and branches that might block sunlight from entering your windows.

4. Seal Up Drafts

Warm air can escape quickly if your home isn’t sealed up tight. Before temperatures really drop, check for drafts around windows and doors and seal them with weatherstripping, caulk or door sweeps. Adding insulation in attics, crawl spaces and basements can also help you stay cozy while lowering your energy bills.

5. Invest in a Programmable Thermostat

A programmable thermostat makes it easy to save money without sacrificing comfort. Try setting your thermostat back 7 to 10 degrees for about 8 hours a day while you’re asleep or out. You could save up to 10% on your heating bills. The thermostat does the work for you, so you don’t have to think about it — and you can program the changes for when you’re asleep or out of the house.

6. Schedule Heating System Maintenance with FSi Oil Services

One of the best ways to ensure comfort and efficiency all winter long is to book annual furnace or boiler maintenance with the trusted team at FSi Oil Services.
