"My technician Keith was great. Friendly and super informative. Also too a quick look at the entire drainage system and gave my an idea of where problems will pop up the future without preventative measures (my home was built in the 50s and while the previous owners took really good care of the house nothing has been gutted and replaced yet)."

"Boiler wasn't lighting on one of the coldest days of the year. The Tech from Vitt showed up that very day and quickly diagnosed a bad Spark Ignition Module. He replaced it and we had heat again. I would hire them again."

Install Boiler questions, answered by experts

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.
